o'day 34 sailboat review

Review of O'Day 34

Basic specs..

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.

The O'Day 34 has been built with different keel alternatives.

One option is a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a full keel.

The boat can enter even shallow marinas as the draft is just about 1.31 - 1.41 meter (4.30 - 4.60 ft) dependent on the load. See immersion rate below.

Another option is a fin keel.

The boat can enter most marinas as the draft is just about 1.71 - 1.81 meter (5.61 - 5.91 ft) dependent on the load. See immersion rate below.

O'Day 34 is typically equipped with an inboard Universal diesel engine at 24 hp (17 kW). Calculated max speed is about 5.8 knots

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

What is Capsize Screening Formula (CSF)?

The capsize screening value for O'Day 34 is 2.04, indicating that this boat would not be accepted to participate in ocean races.

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 7.2 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for O'Day 34 is about 205 kg/cm, alternatively 1152 lbs/inch. Meaning: if you load 205 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1152 lbs cargo on the boat it will sink 1 inch.

Any O'Day 34/35 racers out there?

• Add to quote

I've been racing my O'Day 34 and haven't been able to get her up to her PHRF rating. Just wondering if any other O'Day owners have any experience in racing there boat. Thanks.  

Racing an Oday 34/35 My boat is an Oday 30, but it is similar enough that what I have learned may be applicable. Initially, I had difficulty pointing high, and could only tack through 100 degrees, which was not competitive. When I measured and calculated the sheeting angles, I found my particular leads were 11.5 degrees off the centerline. So I rigged barber haulers, and pulled the sheets in to nine to ten degrees off the centerline. This let me tack through 90 degrees in most conditions. The Oday 30 is undercanvassed for light air, but a taller mast was not in my budget. I did optimize my sail inventory as best as possible, with three used Kevlar headsails from J-105s, two lightly-used symetrical spinnakers, and one new asymetrical spinnaker with a sock. These were all a help in picking up the pace. If you click on my name, you'll see a picture of the Kevlar 140 percent number two genoa in a single handed race off Los Angeles.  

I would like to know how you attached the barber haulers. Do you have any photos? What did you attach them to? I just blew out the lower panel on my mylar genoa. I have been searching for used racing sails. There are a lot of Jboat used sails out there. The J105's seem too small in the foot, and J120's are way too big.  

Oday Barber Hauler With my Kevlar 155 and 140 percent Genoas, I just used a small snatch block attached to a line, and cranked it in from the windward sheet winch. With my high-clewed 133 percent cruising genoa, I used the same block and line, but cranked it from the windward cabin top winch. With my no. 3 blade, I attached a snatch block at a fixed distance from each side of the mast collar with a "Loup". Regarding the sails, the J-105 has the same "J" dimension as my Oday 30, but a slightly longer "I", requiring minor recutting. I was able to find a few J-105 owners who had slightly used 155% and 140% genoas for PHRF racing by actually advertising on the J-105 web site. I used a class jib for my blade. I even found a beautiful symmetrical spinnaker from a J-105. Those guys have deeper pockets than I do! If you have a 43 by 14 foretriangle, you might look at the J-35s. They have slightly larger J and I dimensions, but a fairly simple luff recut could make their headsails fit for about $300 apiece. If you leave the tack where it is, but tip the head back (down the leech) you will raise the clew. This will have the benefit of narrowing your sheeting angle a bit, because the lead will be shifted aft.  

What is the web address for the J-105 website? Where would the J35's advertise? I'll give it a try. Thanks.

O’Day 30

With good performance, low maintenance, and a big interior, the 30 is a good coastal cruiser..

The first O’Day 30 we saw back in 1977 was named Moby Dick . Compared to most of the boats in our boatyard, she did look a lot like a great white whale: beamy white hull with high topsides, white deck, white cabin trunk, and not much exterior wood trim. But what really struck us about the boat was the amount of interior volume. The boat had as much interior space as most 34-footers built at that time.

With her straight sheerline and short overhangs, the O’Day 30 was not as handsome to our eyes then as more traditional-looking boats, but the design has held up surprisingly well. Today it still looks quite modern, yet more conservative than many newer Eurostyled boats.

Over 350 O’Day 30s were built between 1977 and 1984. During 1984, the 30 was modified by changing the keel and rudder, and the stern was lengthened to accommodate a European-style boarding platform. This “new boat” was called the O’Day 31, and it stayed in production until 1986.

O’Day 31 hulls are numbered, quite correctly, as a continuation of the O’Day 30 series. About 150 “stretched” O’Day 31 models were built.

Sailing Performance

With a typical PHRF rating of 177, the O’Day 30 is very close in speed to other modern cruiser/racers of the same length. The boat was never marketed as a racing boat: performance cruising has always been an O’Day concept.

The boat was originally built in two underwater configurations: a keel/centerboarder, and a fin keel of moderate depth. The centerboard version of the boat is about 500 pounds heavier than the keel version. The extra weight is mostly in ballast to give the two boats similar stability. Where PHRF committees distinguish between the two underwater configurations, the centerboard boat is rated about three seconds per mile slower—about what you would expect for the difference in displacement.

Upwind performance is good. Shrouds and genoa track are inboard, and the hull and keel shape from C. Raymond Hunt Associates is clean and modern without being extreme. Downwind, the boat is slow without a spinnaker.

The mainsail is very high aspect ratio, almost 4:1. Off the wind, this is ineffective sail area, and a poled-out headsail will not provide enough area in light air to really keep the boat moving. At the very least, an asymmetrical cruising spinnaker is called for.

Because the mainsail is small, the boat needs large headsails, and they will need to be changed frequently for optimum performance. With a small main, reefing is a relatively ineffective way to reduce sail area.

Standard sails with new boats were a main and 110% jib. In addition, the boat really needs a 150% genoa and a 130% genoa for good performance in a wide range of wind velocities. With a wide waterline beam and 40% ballast/displacement ratio, the boat can carry a fair amount of sail.

Unless the original owner specified the optional larger headsail sheet winches, you’ll have to consider upgrading if you go to big genoas: the stock winches are too small for headsails larger than 110%.

Most owners report the boat to be well-balanced under sail, but some early boats suffered from a lot of weather helm due to an excessively-raked mast. The solution is to shorten the headstay and eliminate almost all mast rake. This may require shifting the mast step aft 1/2″ for the mast to clear the forward edge of the mast partners.

Although the rig size did not change over the course of production, spars from three different manufacturers were used in the boat. The original rigs are by Schaefer. Kenyon spars were used in the middle of the production run, Isomat rigs in later boats. All the rigs are stepped through to the keel, and are properly stayed.

The standard location for the mainsheet traveler is on the bridgedeck at the forward end of the cockpit. From a purely functional point of view, this is a good location. Several owners in our survey, however, complain that the traveler limits the installation of a cockpit dodger. As an option, the mainsheet traveler was available mounted on a girder atop the deckhouse.

This is a tough call. The bridgedeck location is very handy for shorthanded cruising, since the person steering can reach the mainsheet from the helm, particularly on tiller-steered boats. At the same time, a good dodger is almost a must for cruising, and the midboom sheeting arrangement simplifies dodger design.

Although wheel steering was an option, you’ll find it on a large percentage of boats. Owners report no problems with the wheel installation. Early boats have a conventional, centerline backstay. On later models, a split backstay was standard, permitting a stern boarding ladder to be mounted on centerline.

All things considered, the O’Day 30 is a boat that performs well under sail. She’s not really a racer, but she will stay up with almost any boat of her size and type, and is easy to handle, to boot.

O’Day was one of the first big builders to take the all diesel route, even though the Atomic 4 was still a popular engine when this boat went into production. Not all of the engine installations in the O’Day 30, however, have been equally successful.

Originally, the boat was equipped with a singlecylinder, salt water cooled, 12 hp Yanmar diesel. This was one of the first Japanese diesels on the market, and one O’Day 30 owner reports that Yanmar replaced his engine—three years after the boat was built—due to a series of problems that simply could not be solved.

During 1978, the engine was upsized to a Yanmar 2QM15, since the boat was really underpowered with the smaller engine. Owners report that Yanmar installations are noisy, which is partially due to the fact that there is no sound insulation in the engine compartment.

As first built, the engine beds were attached to the walls of the engine box. According to one owner, this was such a bad arrangement that the vibration from the engine loosened the beds. Later boats have a molded fiberglass engine bed/drip pan combination, which is far better than the original installation.

With 1980 models, the Yanmar engine was dropped in favor of a two-cylinder, 16 hp Universal diesel. Owners report no problems with this engine.

Engine access is very good, particularly on later models. In early models, a panel behind the companionway ladder must be unscrewed to get to the front of the engine. On later models, a sloping panel in front of the engine can be removed, and the galley counter over the top of the engine can be lifted out of the way for complete access.

Lack of sound insulation is the weak point of the engine installation. It probably would have cost about $100 to provide halfway-decent sound insulation in the engine compartment when the boat was on the assembly line. You can do it after the fact, but not as simply or cheaply. We’d highly recommend this project, since without insulation the engine compartment resonates like a drum.

With the exception of the original, single-cylinder Yanmar, all of the engines are big enough to push the boat to hull speed in most conditions.

The standard, exposed, two-bladed solid prop causes a fair amount of drag under sail, but you should probably keep it unless you race. We feel a folding prop is not the way to go on a cruising boat, and a feathering prop would be disproportionately expensive on this boat.

Early boats have an 18-gallon aluminum fuel tank. Later models—after 1980—are usually equipped with a 26-gallon aluminum tank. The larger tank gives better range under power, despite the fact that the more powerful engines used late in the production run also use more fuel.

Construction

The hull of the O’Day 30 is an uncored fiberglass laminate. Hull stiffness is increased through the use of a full-length molded body pan, glassed to the hull. Construction is basically solid, but is certainly not fancy. Owners in our survey report a fairly standard number of minor production-boat complaints: surface crazing in gelcoat, leaks around mast, leaks around deck hardware and ports, poor interior finish quality. Gelcoat blistering is neither more nor less common than on other boats.

The O’Day 30 was one of the first small cruising boats to use Navtec rod-type chainplates, which are anchored to the body pan. This is a good, strong arrangement.

In our experience, O’Day’s approach to building was to use good-quality fittings, combined with reasonably sturdy construction. The boats generally have pretty mediocre finishing detail, and costs were kept down by keeping the standard boat fairly simple.

For example, there is no sea hood over the main companionway. This may seem like a minor shortcoming, but it means that this hatch is going to leak if you take solid water over the deck. Instead of a labor-intensive full-length teak toerail, there are short, thin teak strips screwed to a raised, molded fiberglass toerail. The strips do not have to be curved or tapered, since they can be easily bent to shape.

Likewise, most of the interior furniture is part of the molded body pan, trimmed out with teak. The cabin sole is fiberglass, with teak ply inserts. You do not buy these boats for their high-quality joinerwork, nor do you buy them for sophisticated systems or creature comforts.

A single battery was standard, as was a two-burner alcohol stove without oven. Propane cooking was not an option. Double lifelines were optional. Even a spare winch handle was an extra-cost option: only one winch handle was supplied, although four winches were standard!

Because the O’Day 30 is a relatively heavy boat, its basic construction is fairly expensive. To keep the price comparable to other boats in its size range, costs had to be cut somewhere, and they were cut in finish, detailing, and systems. You simply can’t build a boat that weighs 500 to 1000 pounds more than the competition, provide the same systems and detailing, and keep the price the same.

All in all, this is a reasonable tradeoff. You could, if you wanted, add a propane stove, bigger batteries, engine compartment insulation, bigger winches, and many of the other things that you might expect to find on a well-equipped 30-footer. But you won’t get your money back when you sell the boat. The price of your used O’Day 30 will be controlled by the price of other O’Day 30’s on the market, even if they are less well equipped than your own.

The standard water tank varies in capacity from 25 to 30 gallons, depending on the model year. On late models, which have the smaller tank, you could also get an extra 25-gallon water tank, which is mounted under the port settee. With this tank full, the boat has a noticeable port list. Without the optional tank, water capacity is inadequate for cruises extending beyond a long weekend.

Deck layout is reasonably good. There is an anchor locker forward, although its so large that it’s tough to straddle while hauling in the anchor rode. You can walk forward on deck outboard of the shrouds on either tack.

The cockpit is fairly small, thanks to the big interior. There is a large locker to port that can be used to store sails, and a small locker to starboard at the aft end of the cockpit.

With 1980 models, ballast was reduced by 350 pounds in the keel version, 400 pounds in the centerboard boats, according to factory specifications. Still later, ballast in the keel version was increased by 150 pounds. Although these are significant changes, owners of later boats do not report that the boat is noticeably more tender, nor do the PHRF ratings reflect any change in performance.

With her wide beam and long waterline, the O’Day 30 has a big interior. In fact, we have little doubt that if the boat were still in production, O’Day would have figured out how to modify the interior to get three in separate cabins, which has become fairly common on contemporary 30-footers.

For the first three years of production, the boat had a very standard interior, with settees on either side of the main cabin. In 1980, the interior was retooled. The starboard settee was replaced with a U-shaped dinette with permanent table, and the head compartment was shifted to the starboard side of the boat.

The forward cabin in the old layout is bigger due to the placement of partitions and doors, which gave more cabin sole area. With the V-berth insert in place to give a double berth, you could still stand up in the forward cabin to dress. In the newer interior, there is no place to stand in the forward cabin if the door is shut.

Headroom is 6′ on centerline in the forward cabin. There is a molded fiberglass hatch in the forward end of the cabin trunk. In our experience, molded glass hatches are a compromise. They are easy to distort by overtightening hatch dogs to compensate for old gaskets. If dogged unevenly, they tend to leak. It is also next to impossible to fit a dodger on a hatch like that on the O’Day 30, so it must be kept shut in rain or bad weather. Since the boat lacks any real provision for foul-weather ventilation, it can be stifling below.

Although the head compartment in both interior layouts is small, it’s a fairly good arrangement. To use the optional shower, doors to both the main and forward cabins can be closed off, giving plenty of elbow room. Unfortunately, the shower drains to the bilge, a nasty arrangement.

In the original layout, a dropleaf centerline table divides the middle of the main cabin. Four people can sit comfortably at the table using the two settees.

Four diners are far more cramped in the dinette than with the two-settee arrangement, even though O’Day’s literature claims space for five. There’s no way that anyone seated on the port settee opposite the dinette can reach the table. On the plus side, fore and aft movement through the boat is not restricted by the dinette, as it is in the two-settee interior when the table is in use. You pays your money and takes your choice on this one.

Storage space behind the settees shrank in the new interior, a significant loss on a boat this size.

The dinette table drops down to form a good-sized double berth, but because the mattress is made up of five (count’em) separate cushions, this is not a very comfortable berth to sleep on. Its shape is so complex that making sheets fit well is just about an impossibility. In the old layout, the port settee can be extended to form a more normally-shaped double.

Even with opening ports, ventilation in the main cabin is pretty mediocre. There is room atop the cabin aft of the mast for a small aluminum-framed ventilation hatch, and this was an option on later boats. If you don’t have the hatch, you should add it. Cowl vents—other than one on the foredeck—weren’t even options, but could be added.

Headroom in the main cabin is 6′ 3″ on centerline aft, slightly less at the forward end of the cabin. The galley and nav station are the same in both interiors, but some detailing varies depending on the year. Aft to port there is a stove well, with storage outboard.

The icebox is in the aft port corner of the galley. It is not particularly well insulated, and drains into the bilge. There is a deep single sink next to the icebox.

Originally, there was a long step from the companionway to the top of the galley counter, to which a teak board was fastened to form a step. Stepping on galley counters offends our sensibilities, since we prefer to delete the sand from our sandwiches.

Later boats have a more conventional companionway ladder, eliminating the giant first step and the possibility of a foot in the middle of your lasagna, but making it difficult to use the galley counter, now hidden behind the ladder. There is a compact nav station opposite the galley. It has a small chart table, and some storage and space for electronics outboard. The chart table must be kept small to give access to the quarterberth.

You’ll find the electrical panel in one of two places: under the bridgedeck in the galley, or outboard of the chart table. The nav station location offers more protection from water coming down the companionway—which it will—but space for electronics is sacrificed.

Sales literature refers to the quarterberth, which is 41″ wide at its head, as a “cozy double.” Cozy isn’t really the word for a “double” berth that tapers to less than 2′ wide at the foot. Forget it. Many owners have added an opening port from the quarterberth into the cockpit, and this helps ventilation a lot.

The interior of any 30′ boat is a compromise. For the coastal cruising for which she was designed, the interior of the O’Day 30 is spacious and functional, and is probably the boat’s best selling point.

Conclusions

With her good performance and big interior, the O’Day 30 makes a reasonable coastal cruising boat. This is a low-maintenance boat, with little exterior wood. Along with low maintenance, you get pretty plain-Jane appearance.

The boat still looks modern. If she appeared in a boat show today, she wouldn’t look dated.

Unless you need shoal draft, we’d opt for the deepkeel boat, for its simplicity, if nothing else.

The extended stern of the O’Day 31 makes that boat much better looking in our opinion, since the big, fat stern of the 30 is probably her least attractive feature. The 31′ boat is far more expensive on the used boat market, however, so you have to decide how much you’re willing to pay for improved looks and a boarding platform.

Compared to a lot of newer 30-footers, the O’Day is quite heavy, but we consider that a plus for a boat that may sail in fairly exposed waters. For the type of use most boats this size will get, the boat looks like a good value on the used boat market. You could spend a lot more money for a lot less boat.

Good day to you. I am having a hull problem with my 1980 oday30. I bought it only a few years ago and when i was getting her ready for this season sailing i noticed a small hole where the bilge pump sits so i took it off and apparently ice had formed over the winter causing the inside layer to crack. This allowed moisture to enter and soak a good section of the hull above the fiberglass hull. I am getting conflicting reports how to fix this. Some say take all of the first layer out and re core it and fiberglass again. And some say you can fix the core with little attention to really fixing the problem. I have a hole about 1 foot by 5 inches and all cleaned up but i am pretty sure there is still moisture forward of the hole and near the mast. Ok so i am looking for your opinion please and thank you!!!

I just used Injectadeck. Worked great for a similar problem in my cabin.

My recommendations are (1) if you intend to buy a selfsteering , that you buy an auxiliary type for two reasons. One they provide a means of if your is compromised underway and two, these vanes help eliviate the side loading on these spade rudders when slewing off swells.

Sailboat Guide 1983 O'Day 34 Description Seller's Description The O’Day 34 is one boat that will please both the competitors and cruising sailors. It’s a high-performance sea-going cruiser designed by John Deknatel of Raymond Hunt Associates to offer the speed and roominess of a much larger boat with the handling and responsiveness of a smaller boat. It offers the comforts and amenities of a well-appointed yacht. This is a very clean yacht which shows as the pictures depict. It has brand new sails, including a full batten Main with reefing points, 135 furling Genoa, and a Spinnaker. The sheets are new, and the halyards were recently replaced. The Gelcoat on this boat still shines and is not dull like most boats it’s age. This is the perfect boat for the adventurous type that likes to ocean cruise yet has enough space to live aboard comfortably.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more. Classic hull speed formula: Hull Speed = 1.34 x √LWL Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL Sail Area / Displacement Ratio A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more. SA/D = SA ÷ (D ÷ 64) 2/3 SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay). D : Displacement in pounds. Ballast / Displacement Ratio A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize. Ballast / Displacement * 100 Displacement / Length Ratio A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more. D/L = (D ÷ 2240) ÷ (0.01 x LWL)³ D: Displacement of the boat in pounds. LWL: Waterline length in feet Comfort Ratio This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 ) D: Displacement of the boat in pounds LOA: Length overall in feet Beam: Width of boat at the widest point in feet Capsize Screening Formula This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions.

Is it strong enough? How are its sailing charactoristics for bluewater sailing? These boat seems to be a good bargin. Can anyone give me some information? Thanks   o-day 34 Marion to Bermuda I don't think anyone would call a 34 a "bluewater boat" but the 34 won the Marion to Bermuda race in the early 1990's. I have a 35 and am preparing for the same trip. It's a great boat by the way.Dave   Justin - O'day Owners' Web The great debate Before we begin - any boat can sail anywhere on the right day, and any boat will get you very badly messed up on the wrong day - so, what matters is: how will you use the boat? If you want a boat that can do extended cruising the 34 may be a good pick. If you're comparing it to something like a Cabo for riding out a hurricane - I'll take the Cabo.If you give us some more information on how you think you'll use the boat, we can help determine if its a good pick for you.Justin   Pick your fight I have never had mine in open seas, however, I have been caught in 40kt+ winds in large inland lakes with high wave action. It handled as well as anyone could expect from any sailboat. I would not be reluctant to set out on an extended deep water cruise in it, however, I would certainly be cautious about the time of the year and weather conditions. Personally, I wouldn't attempt any passage during hurricane season in any boat, sail or otherwise. The O'Day 34 is a solid built dependable boat that I have developed a great deal of confidence in. I wouldn't be afraid to take it anyplace.I see that you are Tennessee boy. I don't know where Greenback is but if you would like to see my boat, it's at Pickwick. I can be reached via [email protected].   Mike Whalen Greenback J.B. Greenback is just south of Knoxville on Hwy 411 at the foot the Great Smokey Mountains. Is Pickwick a little tight for a 34? I sail my 25 here further up the Tennessee River at Ft. Loudon Lake (knoxville) but grew up in Memphis and often went to Pickwick. Nice area expept for the smell of that paper plant.Later,Mike   Not Really Nope, Pickwick is really a pretty good size body of water but not as big as Kentucky Lake. I moved down to Pickwick last year because it was a shorter drive. There really isn't as much room as KL but you get used to it after a while. I find the conveniance of being closer to the boat off sets the smaller sailing area. It also puts me right at the mouth of the Tombigbee and just around the corner from Alabama up the Tennessee River. It's actually an ideal location for inland sailing. And as to size, there is one 40footer and a lot of larger motor yachts.The biggest asset to the O'Day34 is the 47 foot mast and the relativily shallow draft. I can take this thing just about anywhere I want to without worrying about demasting it or any other preparations.The smell of the plant is not as bad as you think. During the summer months, the wind blows mostly from the S/W keeping it away. It's hardly ever a problem.Come on down sometime when your slumming!   This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.

Review of O'Day 34 The O'Day 34 has been built with more than one type of keel. One option is a finn keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a long keel.
