Rig and Sails

Auxilary power, accomodations, calculations.

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. Read more.

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. Read more.

CSV = Beam ÷ ³√(D / 64)

Displayed here is the MIII version which has a deeper swing keel and twin rudders designed by Humphreys. Specs above apply to Mk 2 thru 4.

The first version of 115 was a Carter design. Displacement:14,600 Ballast 6978 Board up 2’3” Board Down 6’8”

The Southerly 115 Sailboat

The Southerly 115 is a versatile and seaworthy cruising sailboat that features a unique swing keel system that allows it to sail in shallow waters and dry out on the beach. Designed by Dick Carter and Rob Humphreys, the Southerly 115 was produced by Northshore Yachts of Chichester, England, from 1983 to 2011.

The boat has a spacious centre cockpit, a comfortable interior layout, and a range of rig and sail options to suit different sailing preferences. It is a popular choice for sailors who want to explore remote and varied cruising grounds without compromising on performance or comfort.

A Few FAQs about the Southerly 115 ...

Based on the published design ratios for the Southerly 115, how is the boat likely to perform under sail?

Based on these ratios, the Southerly 115 can be classified as a heavy displacement cruising boat with moderate sail area and high stability. The boat is likely to perform well in strong winds and rough seas, but may be slower and less responsive in light airs. The boat has a good balance of speed and comfort, and can handle a variety of sailing conditions.

Is the Southerly 115 still in production and, if not, when did production end and how many of these sailboats were built?

The Southerly 115 is no longer in production. The last model was built in 2011, when Northshore Yachts ceased trading due to financial difficulties. According to the Southerly Owners Association, a total of 224 Southerly 115 boats were built over four generations: Mk I (1983-1988), Mk II (1988-1994), Mk III (1994-2005), and Mk IV (2005-2011).

What, if any, alternative versions of the Southerly 115 were built and what are the differences between them?

The Southerly 115 underwent several changes and improvements over its production history, resulting in four distinct versions:

  • The Mk I version had a triangular airfoil-shaped drop keel and a single shallow rudder. It had a fractional rig with a self-tacking jib and an optional cutter rig. It had a two-cabin layout with a double berth aft and a V-berth forward.
  • The Mk II version had a more streamlined drop keel with a bulb at the bottom and a twin rudder system. It had a masthead rig with a genoa and an optional cutter rig. It had a three-cabin layout with two double berths aft and a V-berth forward.
  • The Mk III version had a redesigned hull shape with more freeboard and volume. It had a deeper drop keel with more ballast and a twin rudder system. It had a masthead rig with a genoa and an optional cutter rig or ketch rig. It had a three-cabin layout with two double berths aft and an offset double berth forward.
  • The Mk IV version had an improved drop keel mechanism with hydraulic control and an indicator gauge. It had a twin rudder system with optional skegs for better directional stability. It had a masthead rig with a genoa and an optional cutter rig or ketch rig. It had a three-cabin layout with two double berths aft and an offset double berth forward.

How many people can sleep on board a Southerly 115?

The Southerly 115 can sleep up to eight people on board, depending on the model and configuration. The boat has three cabins that can accommodate six people in double berths, plus two more people in the saloon that can be converted into single berths.

How did the sailing press review the Southerly 115?

The Southerly 115 received mostly positive reviews from the sailing press, praising its versatility, performance, and comfort. Here are some excerpts from some of the reviews:

  • "The Southerly 115 is a boat that can take you anywhere. It has the ability to sail in deep water with a good turn of speed and point high to the wind, yet at the touch of a button, the keel can be raised to give a draft of just over two feet, allowing you to explore shallow creeks or dry out on a beach." (Sailing Today, 2006)
  • "The Southerly 115 is a well-built, well-designed boat that offers a unique combination of shoal draft and good sailing qualities. It is not a boat for everyone, but for those who value the freedom and flexibility that it offers, it is hard to beat." (Sail Magazine, 2008)
  • "The Southerly 115 is a boat that can do it all. It can cross oceans, cruise coastlines, and venture into the shallowest of waters. It is a boat that can adapt to your sailing style and preferences, whether you want a simple sloop or a fully rigged ketch. It is a boat that can provide comfort and convenience for long-term living aboard or short-term holidays." (Yachting Monthly, 2010)

What do owners of the Southerly 115 have to say about their boats?

Owners of the Southerly 115 are generally very happy with their boats, and often share their experiences and adventures on blogs, forums, and social media. Here are some quotes from some of the owners:

  • "We have owned our Southerly 115 for over 10 years and have sailed her extensively in the UK, Europe, and the Caribbean. She has been a fantastic boat for us, reliable, comfortable, and fun to sail. We love her swing keel system, which allows us to access places that other boats can't. She has been our home away from home and we have made many wonderful memories on board." (Chris and Laura Mlynarczyk, owners of Blue Sky)
  • "Our Southerly 115 is our dream boat. We bought her in 2012 and have since sailed her around the world. She has performed brilliantly in all kinds of conditions, from light winds to storms, from calm seas to big waves. She has been spacious enough for our family of four and our guests, and cozy enough for just the two of us. She has given us the freedom and flexibility to explore new horizons and discover new cultures." (Mark and Sue Sanders, owners of Distant Shores)
  • "We have owned our Southerly 115 since 2009 and have sailed her mainly in the Mediterranean. She has been a great boat for us, easy to handle, fast, and comfortable. We love her center cockpit design, which gives us a lot of privacy and protection. We also love her variable draft, which allows us to anchor close to shore or dry out on the sand. She has been our perfect cruising companion." (Peter and Anne Jones, owners of Sea Mist)

What is the history of the builders of the Southerly 115 and is the company still in business?

The builders of the Southerly 115 were Northshore Yachts Ltd., a British company founded in 1971 by John Baker and Tom Richardson. The company started by building small sailing dinghies and later expanded to larger cruising yachts under the Southerly brand. The company was known for its innovative designs and high-quality craftsmanship, and became one of the leading manufacturers of swing keel sailboats in the world.

Unfortunately, Northshore Yachts went into administration in 2013 due to financial difficulties caused by the global recession and declining sales. The company was acquired by another British company called Discovery Yachts Group Ltd., which continued to produce some of the Southerly models under a new name: Discovery Swing Keel Yachts Ltd.

However, in 2019, Discovery Yachts Group also went into administration after facing legal disputes with some of its customers and suppliers. The company was taken over by another British company called Binti Marine Holdings Ltd., which currently owns the rights to the Southerly brand and plans to resume production of some of the models in the future.

Is the mast on the Southerly 115 deck-stepped or keel-stepped?

The mast on the Southerly 115 is deck-stepped on a stainless steel compression post that rests on a reinforced bulkhead below. This arrangement allows for easier maintenance and inspection of the mast base and wiring.

What keel options, if any, are available for the Southerly 115?

The Southerly 115 has a unique swing keel system that allows the boat to adjust its draft from 0.69 m (2 ft 3 in) to 2.46 m (8 ft 1 in) by using a hydraulic ram. The keel is made of cast iron and has a lead bulb at the bottom for extra stability. The keel can be raised or lowered by using a control panel in the cockpit or at the chart table. The boat also has an indicator gauge that shows the position of the keel at any time.

What is the average asking price of a secondhand Southerly 115?

The average asking price of a secondhand Southerly 115 depends on the model, condition, and equipment of the boat, as well as the location and market demand. According to YachtWorld, a global online marketplace for boats, the current range of prices for a used Southerly 115 is from £59,950 to £199,950, with an average of £114,950.

How does the Southerly 115 compare to other similar sailboats in its class?

The Southerly 115 is a unique sailboat in its class, as it offers the versatility of a swing keel system that enables it to sail in deep or shallow waters. There are not many other sailboats that have this feature, but some possible competitors are:

  • The Feeling 1090, a French-built sailboat that has a lifting keel and twin rudders. It has a similar length and beam to the Southerly 115, but a lighter displacement and less sail area. It has a two-cabin layout with a double berth aft and a V-berth forward.
  • The Ovni 365, an aluminum-hulled sailboat that has a lifting keel and twin rudders. It has a slightly longer length and beam than the Southerly 115, but a heavier displacement and more sail area. It has a three-cabin layout with two double berths aft and an offset double berth forward.
  • The Sirius 35 DS, a German-built sailboat that has a lifting keel and twin rudders. It has a shorter length and beam than the Southerly 115, but a similar displacement and sail area. It has a two-cabin layout with a double berth aft and an offset double berth forward.

What other sailboats have been created by the designer of the Southerly 115?

The Southerly 115 was designed by two renowned naval architects: Dick Carter and Rob Humphreys.

Dick Carter was an American designer who was famous for his successful racing yachts in the 1960s and 1970s, such as Red Rooster, Rabbit, and Imp. He also designed several other cruising yachts for Northshore Yachts, such as the Southerly 100, 105, and 110.

Rob Humphreys is a British designer who is known for his innovative and versatile designs for various clients, such as Oyster Yachts, Elan Yachts, and Moody Yachts. He also designed several other models for Northshore Yachts, such as the Southerly 135, 38, and 47.

Review of Southerly 115

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 boat is equipped with 8 berths.

The Southerly 115 is equipped with a swing keel. A swing keel is a pivoting lifting keel, allowing to sail both coastal and inland waters.

The boat can enter even shallow marinas as the draft is just about 0.69 - 0.79 meter (2.26 - 2.56 ft) dependent on the load. See immersion rate below.

Southerly 115 is typically equipped with an inboard Yanmar diesel engine

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 Southerly 115 is 1.95, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Southerly 115 is about 272 kg/cm, alternatively 1527 lbs/inch. Meaning: if you load 272 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1527 lbs cargo on the boat it will sink 1 inch.

Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

What is L/B (Length Beam Ratio)?

What is a Ballast Ratio?

SA/D (Sail Area Displacement ratio) Indicates how fast the boat is in light wind: - Cruising Boats have ratios 10-15 - Cruiser-Racers have ratios 16-20 - Racers have ratios above 20 - High-Performance Racers have ratios above 24 Sail-area/displacement ratio (SA/D ratio): 15.89

Southerly 115 Boat Comparison

. . . and two true centerboarders

It is often said that all boats are compromises, but that is especially true with regard to cruising center-boarders when it comes to deciding how much the centerboard box should be allowed to intrude into the interior accommodations. Another factor is whether the builder wants to offer the centerboard configuration as an option on an existing production boat designed originally with a deeper keel. Invariably, the board does not obstruct the interior but resides below the cabin sole in a stub keel that also contains the majority of the ballast. The resulting boat is not really a true centerboarder but a compromise keel/centerboarder. The draft is only partially reduced, and the combination of two markedly different foils is not the best combination for aerodynamic efficiency. The absolute minimum draft can only be achieved by retracting the foil completely into the hull or “canoe body.”

It’s no secret that I like center- boarders. I even own one, our C&C Corvette, Trillium IV . I like the shoal draft they offer, and from my days racing and designing International 14s, I’m comfortable with the center-board or daggerboard concept. It’s refreshing, therefore, to look at three true centerboarders, where the entire foil is housed in the hull so that the minimum draft is that of the canoe body and the resulting efficiency of the foil is not compromised by a stub keel. The featured Southerly 115 and the Tanzer 10.5 are from the always innovative Dick Carter, while the Clearwater 35 is from Craig Walters, who, like so many other talented designers, started his career in the Carter design office.

I should also say that, even though I’m referring to these boats as centerboarders, they are probably more accurately described as having lift keels. That is certainly the case for the Southerly, where the centerboard, which weighs about 2,500 pounds, accounts for more than 30 percent of the entire ballast.

It is also interesting to see how each boat addresses the problem of what to do with the rudder when the keel is completely retracted, since the rudder cannot be deeper than the canoe body if that minimum draft is to be achieved. The version of the 115 reviewed is a later Mk IV model modified by Rob Humphreys to incorporate twin shoal- draft fixed rudders, while the Tanzer’s rudder retracts up the transom on a small fixed skeg, and the Clearwater’s rudder pivots aft to reduce draft. The goal, of course, is to still have enough rudder in the water to steer the boat effectively when the keel and rudders are completely retracted.

The other trade-off with a center- boarder is that, in order to achieve the minimum draft of the canoe body, the majority of the ballast is housed in the bilge, not in a deep fixed keel. This results in a significantly higher center of gravity, with a resulting reduction of sailing stability. In almost all cases, shoal-draft boats are given more beam to compensate for the higher CG by increasing form stability. We see this with all three of our chosen boats having beam/LWL ratios over 40 percent. To further increase stability, all three of the boats have large amounts of ballast, resulting in ballast/displacement (B/D) ratios higher than 40 percent in the Tanzer and the Clearwater and a whopping 50 percent in the Southerly.

Although not visible on our drawings, it is also interesting to see how each designer addressed the challenge of the centerboard box intruding into the interior. The Southerly and the Tanzer, coming from the same designer, incorporate the same solution of having the box form the end of the galley and the dinette. In the Clearwater, on the other hand, the whole interior is structured around the box.

If we can trust what the numbers tell us about relative performance, the Clearwater 35 excels with the lowest displacement/LWL (D/L) ratio of 235, compared to 279 for the Tanzer and a hefty 327 for the Southerly. The Clearwater also has the highest sail area/displacement ratio (SA/D) of a very competitive 18, compared to a more normal 15.9 for the Tanzer and a conservative 14 for the Southerly. However, with its lighter displacement, even with a 45 percent B/D ratio, the Clearwater will be reefing earlier, while the Southerly, with its smaller sail plan, higher B/D ratio, and greater displacement, will be standing up well when the wind gets stronger.

The capsize numbers reflect the wide beams of all three boats, but the lighter displacements of the Clearwater and the Tanzer give them values of 2.1 and 2.0 respectively. Capsize numbers above 2 are a concern for offshore sailing. Although it is slightly beamier, the Southerly comes in at a more conservative 1.9, primarily due to its higher displacement, which, at 15,215 pounds, is a full 50 percent greater than the Clearwater’s.

These boats present three very interesting approaches to the true centerboard concept, achieving absolutely minimum draft for shoal-water cruising by means of lift keels retracted into the canoe body of the hull. From my perspective, the Clearwater is the prettiest of the three, but its interior layout is the most compromised.

Southerly 115 DS. (Series1?)

Look like nice boats, but the keel looks a bit errrmm wimpy. Any views as to how they sail? Can you get reasonably close to wind? What are they like in a heavy sea? Any views?  

Yngmar

The keel is fine and unproblematic if serviced. The interior is well laid out and quite spacious. However, on the 115 Mk1, the rudder is not deep enough and can lose grip in large-ish waves (see boatyard shot at http://www.yachtsnet.co.uk/archives/southerly-115/southerly-115.htm ). That's why later revisions got completely redesigned twin rudders. Apart from this, they have a pretty good reputation. I almost bought one some time ago but the rudder thing put me off in the end. The slightly smaller 105 had a lifting transom-hung rudder which did not suffer from this problem, so that may be an option (she's very similar otherwise). Edit: Forgot to mention, due to the rudder issues, several used Southerly 115s on the market have modified rudders, some well engineered, some less so. Look closely!

They are best sailed fairly flat - reef at 16/17 knots apparent. Never lost steerage as the stern is very narrow. A rudder mod was added (could be retrofitted) which put winglets near the base of the rudder to stop water falling off the rudder. Max depth is 6'8" The Series 2 has a Rob Humphreys designed keel (8'1" fully down) and is much less intrusive that Series 1. It is much stiffer too meaning 20+ knots before reefing. Still had single rudder.

Can't beat a Southerly for spaciousness at the size. We have a 105 that we've been cruising on for the last couple of years. Compared to similarly sized boats, she's huge inside. As for sailing, well, we don't do much of that in the Med... We did pretty well whilst in the Solent, though. Be aware the older Southerlys had relatively small rigs (12m mast on an 11m boat) so it takes a stiff bit of wind (for us at least 10 kts) to get moving at a half decent speed. Ours, as with some others, was modified by the previous owner to swap the single rudder for twin transom hung rudders. The rudders work well, though I did have to fix the bodged implementation!  

Many thanks folks, really appreciate the sharing of experience from people who know. We have a fairly traditional looking 34' MAB GRP boat with a longish deep keel. She sails very well and can take a biggish sea without too much discomfort. However, as we get older, comfort and things like views while "indoors" of an evening, especially in our northern climes, seem to become more important. Also, our present stowage space is restricted, the berths are on the short side, and it's just not quite right for children and their children - too Spartan below, and not a lot of space. The Southerly 115 looks like a nice interior with loads of space, but just not sure about how they'd handle in a blow. I really appreciate the comments about the rudder; this could be significant in our sailing area, the west coasts of Scotland and Ireland. The idea of lifting the keel for shallow waters is attractive, but not critical. We are used to deepish keel sailing, which really is why I raised the keel issue. Everything in sailing, especially cruising, is a compromise. Maybe I'll hang on for a year or two until I finally give up any pretence of even part-time employment..... I might find the ideal boat by then! The 115 DSL looks good, but perhaps the Series 1 is not quite what we want. Many thanks to all for your advice and counsel; we might look at later editions.  

If you liked the layout, the deck salon views of the Southerly and the interior helm for when it's cold out, there are a few other MABs to look at. None of them are built with lifting keels and so didn't have to compromise on the rudder. The first is the Moody Eclipse, which comes in a hard to find 38, a more cramped 33 and a very spacious 43 feet (specs: http://www.moodyowners.net/Moody_Archives/moody_archives.shtml ). They have a very clever-flip up interior helm that folds down below the salon seating when not needed. The other is the Westerly Riviera 35, which stands out with her huge windows (specs: http://sailboatdata.com/viewrecord.asp?class_id=3244 ). Don't remember much about this one, but read somewhere the concerns about the windows breaking when pooped were alleviated by doing a dunk test. And lastly any 1980s Oyster DS (435 or 406 - they come in coachroof versions as well as DS, and several interior layouts). Bit larger, no interior helm, but they tend to be very well built, spacious with a nice interior and have excellent sailing abilities (generally and in heavy weather). Bit on the pricier side though.  

Southerly 115 (unlike some modern Southerlies) is not a deck saloon as such - the galley up layout works very well and saloon is lower down but is both large and comfortable. Other used boats with inside helms: Sadler Panorama (Starlight 39 hull) - very rare Dehler 41DS Vancouver 34 or 38 Sovereign 40 Various Colvic Victors Voyager 35 or 40 Cromarty 36

I can vouch that the Moody Eclipse 43 is a lovely boat to sail. My late parents owned one and I sail plenty of miles on it. It also had quite a shallow keel, so no problem with lifting mechanism. The deck salon was lovely as seated you could see almost alround the boat. Furling main and bow thruster were standard equipment, so easy to handle shorthanded.

We bought a 115 series 3 just 12 months ago - the last version with the single rudder, with wings added, before the twin rudder series 4 I would endorse what a couple of others have said - definitely prefers to be sailed a bit more upright. Keel is 2.6 m when down and seems to point reasonably well There is a lot of weight downstairs, with both the castiron keel and the lump of iron in the grounding plate, which I understand will keep her well planted in a bigger sea, but makes her a bit slow I lighter winds...as someone else points out, not the biggest sail area for a boat of its length and weight But so spacious, solid, well built, a real pleasure to be on. We love ours

    The lowest bridge on the Canal du Midi is reputedly one in Carcassonne. (see insert). Water levels can change the clearances dramatically, sometimes closing canals due to either drought or too much rain. The Southerly 115 with its lifting keel looks like a good candidate for the canals in any case.
