In addition to the above formats, you may encounter those which are preceded by country codes such as "US" for the United states, "CN" for Canada, and "FR" for France. This means that the vessel was built for consumption in that respective country. You may also find hull numbers on two separate lines. In this case the second line is not typically considered as part of the hull number. State assigned hull numbers are not always consistent with federal standards.

This is how to read a hull identification number – hin decoding steps.
Reading a boat HIN means decoding the HIN into its component parts. It is important to know the basics but rest assured that there are tools that do it for you. Knowing how to read your vessel’s HIN will allow you to find out the make and year.
We have already discussed what is a HIN and mentioned all you need to know about HINs in our previous article. Today, we discuss how to read it and explain how to know the builder and year of the boat from the HIN.
When looking at a vessel, you will probably see different markings. You could see the name and hailing port or you might see the state registration number. These would be on the bow and could have the state’s watercraft decal. If the boat is not titled in the state, then it could be documented with the coast guard. In those cases, the bow will have the name and hailing port. The stern will also have the name and hailing port indicated.
There are other numbers on the boat that you will see. Namely, the stern will have the hull ID number plate etched into it. If it is a USCG documented vessel, then you will see the placard having the official number on it in the interior of the vessel.
You can find your HIN Number as shown in the image above. It is on the starboard side of the stern.
The Boat Hull Identification number is 12 characters long. we say characters instead of digits because it is a mix of numbers and letters. It could have “US-” in the beginning for the country code making it 15 character long but usually the country designation is not written so you just have 12 standard characters for the length.
Now that you have found your hull ID number for your vessel, it is time to start reading it or decoding it. As stated earlier, there are tools that do this for you such as the official hindecoder.com website. The HIN decoder is free. #HinDecoder
To start reading your boat’s HIN, you can break it up into the 3 main parts:
The first 3 characters in the Hull Identification number are the manufacturer code. So when you are reading the HIN, you might see “YAM” and this would be Yamaha. It might seem difficult to understand the manufacturer identification code (MIC) but you can simply look it up here:
#BoatManufacturer #Florida #BoatBuilder #Boats #Brands
#BoatManufacturer
Example: YAM” would be Yamaha. The list is based on uscg manufacturers for vessels/yachts.
When you are reading your HIN , you can find out the year and month that your boat was built and its model year as well. The manufacturing month and year are not always the same as the boat model year. The year you were born is important. wouldn’t you want to know when your boat was born?
Start by looking at the last 4 characters of the boat’s HIN. Here is where it can get complicated. There are 3 different formats for HIN numbers from 1972 and 1984. You might see a letter “M” in position 9 if the boat HIN Type format is from 1972. If all 4 characters at the end of the HIN are numbers, then it would be the other format from 1972. Here is a handy table to lookup the month codes .
Below is a video explaining the three kinds of HIN formats.
In short, here are the three hull number formats:
These formats came from the ISO 10087 . This standard is described in detail here and on the hindecoder website .
Example, YAM12345D202 and this would be Yamaha Jet Ski HIN Number. The details of the year and make would be in the HIN decoder . The HIN hin location would be on the transom.
#HINFormats #HINTypes #HullIdentificationNumbers
The HIN formats described above do not contain the model of the boat. It cannot be decoded from the HIN. You can still lookup the boat model name by searching its HIN on hindecoder.com .
The boat hull identification number is also called hull serial number by some people. Having said that, the serial number is actually embedded into the HIN and is 5 characters long after the MIC code as shown in the image above.
If you have a 200hp or 250hp outboard engine, it does not matter because either way the engine should have its own serial number that is different from the 12 character HIN format. The boat engine serial can be used for many applications for boat buyers and boat owners including warranty lookups when working with manufactures to fix something. Again, the Engine serial (created by engine makers) is different from the boat serial number (created by pleasure craft builders during production).
If you are in the USA, Canada, or Australia, they should all be following the HULL ID Number standard that came into effect August 1st 1984 and is subject to ISO 10087:2006(en) . There is no certification for this standard but it must be follows by all boat manufacturers. Even if the vessel is a catamaran or jet ski , it needs a valid HIN and must follow coast guard regulations. Consumers should be aware the steps above how to read a HIN number and tell it apart from boat registration and title numbers. This is a safety purpose from bad sellers and is something surveyors may not check on a used boat!
The articles we have are enough to learn all about HIN numbers so you don’t need any course on the subject but make sure to lookup damage reports and accidents in our Boat-Alert databases. Boat dealers are responsible to title the boat when selling it to you and to do it with the correct HIN and decal stickets.
In conclusion , we have explained how the HIN on a boat is placed on the stern by the manufacturer. We also gave a step by step on how to read your HIN manually and indicated that you can get it decoded automatically at hindecoder.com. You now know how to decipher a pontoon HIN / hull identification number.

Over 16 years in the boating industry, a boat's history affects its value.
Click on these images to reveal the damage.
A boat's history is an essential factor in determining a boat's estimated market value. In addition to age and hours, other things to check for include whether the boat has ever been in an accident, deemed a total loss, and whether it was used in fresh versus salt water. All of these elements will factor into what the boat is worth and how much you should be willing to pay.
Damage to the boat, especially fiberglass boats, can be repaired very easily with almost no trace of its previous damage. Don't get caught off guard by boats with a history of damage and accidents- this could lead to many future problems and thousands in repair costs.
Check if your watercraft has been:
Hurricane Sandy resulted in over $650 million in damages to recreational boats.
Hurricane damaged boats are often sold with a clean title.
Most states do not recognize salvage and damaged titles for boats. Therefore, storm damaged boats are auctioned off to be restored and re-sold to unknowing individuals, with clean titles. These boats may have spent significant time submerged under salt water resulting in detrimental damage that could result in loss later on. Boat History Report® is the only way to know the real truth about the boat, as once repaired- these boats can look better than new to an unsuspecting buyer.
Know when a boat has been in an accident.
Our extensive database searches hundreds of thousands of accident records.
Use Boat History Report® to insure that you don't buy a boat that has been damaged in an accident and then repaired. Boats that have been severely damaged have a low resale value and may not be safe for you and your family.
Boats frequently run aground due to a miscalculation of the water's depth.
Running aground can be one of the most costly problems a boat can endure.
Not only can running aground cause hidden structural damage to the boat, if environmental damage was caused, the new owner could be responsible for the previous owners negligence, as these fines stay with the boat and not the reckless boater. Don't put yourself at risk - Boat History Report® can help you avoid purchasing a boat that has run aground.
Boats are deemed a total loss when the cost to repair is greater than a set percentage of the boat’s value.
Unlike cars, boats have no uniform salvage titling law.
These boats are usually repaired and resold with clean titles, without disclosing previous total loss events. Boat History Report® helps uncover events like these in a boat’s history.
Many boats manufactured often contain dangerous, potentially fatal flaws. Is your boat safe?
Open (unfixed) safety recalls can result in serious injury and sometimes death.
Due to safety concerns, manufacturers report recalls every month; however, numerous flawed boats remain in the marketplace. Check our national database to see if your boat has been issued a safety recall as part of your report from Boat History Report®.
Sinkings and flooding occur more frequently than you may realize.
Boats that have been submerged sustain damage that can take months to surface.
Not only are boats swamped or capsized while in use, but many sink dockside as a result of heavy rains, storm surge, faulty drains or poor sealing thru-hull fittings. The damage is not noticeable immediately, but as corrosion sets in, costly issues will continue to surface. Let Boat History Report® help save you from a boat that could jeopardize your families safety while costing you thousands of dollars to repair.
Boats are constantly seized by U.S. Customs due to illegal activities.
Boat dealers and yacht brokers are not required to report seizure information to customers.
Many times these boats incur serious damage during the seizing activity. Don't unknowingly buy one of these damaged boats - Run a report from Boat History Report® before you buy.
In addition to cosmetic damage, boat fires can also cause hidden structural damage.
Due to skilled fiberglass work, boats involved in fires may appear undamaged to the naked eye.
Once the cosmetic issues are fixed you may never know a fire had occurred. That’s what Boat History Report® is for!
Avoid buying a boat that has been in a collision and then cosmetically repaired.
Similar to cars, boats can sustain structural damage that cannot be seen by the naked eye.
Collisions cause structural damage that can jeopardize safety and will lower the resale value of the boat. Don’t lose thousands by purchasing a damaged boat- run a Boat History Report® and be informed.
Hull identification number (hin) / boat vin.
What's a HIN (boat VIN) and where do I find it?
The Hull Identification Number (HIN) serves as the boat’s unique identifier, similar to the VIN or vehicle serial number of a car. If the dealer or broker listing the boat has not provided you with a report from Boat History Report®, ask them to provide you with the boat’s HIN so that you can run your own report.
The HIN is affixed or stamped into the back of the boat's hull also known as the transom in the uppermost right corner or under the swim platform. Also, the HIN may be stated on the state title, state registration, USCG Documentation, and insurance documents. For boats 1984 and newer, Federal regulations mandate the HIN must follow the format in the image below. For additional HIN formats and a more detailed explanation, be sure to check out our HIN Troubleshooting Guide.

I have an oday and the serial number XDYD69650274. Anyone can help me understand this number?
I think i found the answer on this link - Finding the Hull Identification Number (HIN) XDYD -6965-02-74 manufacture's code - XDY serial number - D6965 month of production - 02 model year - 74
That’s correct. And the Serial Number further decomposes into D for the Daysailor model and 6965 for the specific hull number (which doesn’t necessarily start at 0001).
Thank you.

1,929. Oday Day Sailer Wareham, MA. May 23, 2010. #5. The Hull ID format that Joe refers to didn't start until 1972 (actually, November 1972, for the 1973 model year). The Sprite was built from about 1959-1970, and so was built long before the HIN was used. The HULL# listed on your boat indicates the total number of O'DAY Sailboats built (you ...
There is a Hull # and a Class #. Hull # refers to the total number of O'Days built and Class # refers to the number of that model built. Using my (1969?) Widgeon for an example, Hull# 22698 Class # 1791, means that she was the 22698th O'Day built, and the 1791st Widgeon. The plate may have fallen off before you bought your boat, or been removed ...
MARINER CLASS STYLES/ HULL IDENTIFICATION. YEAR BUILT INFORMATION. The following information will help you determine the Hull Number (Mariner Class/Sail Number), the month and year your Mariner was built and when the different topsides styles were built. From 1963 when the first O'Day Mariner was built until November 1972 the boats had a metal ...
Here's a handy little chart explaining O'Day hull identification numbers. I was curious what year and sail number my boat was and ran across...
O'Day sold his company to the conglomerate Bangor Punta (later Lear Siegler) in 1966. For a number of years, O'Day Corp. was the largest producer of sailboats in the US.
Is there a "decoder ring" posted anywhere on the site that allows you to date a boat by the hull number? Specifically I'm interested in the manufacture date for an OD 22, hull 404. I apologize if this is already posted, but after quite a search I wasn't able to find this info.\u000B\u000BThank you in...
The Hull# represented how many total boats O'Day had built, and the Class# represented how many of that Class O'Day had built. So your 1967 DS I was the 15344th boat that O'Day built, and the 2724th Day Sailer. If there is a number on your sail, it should be the Class# 2724. This was O'Day's method of serial numbers for their boats until the 12 ...
The class number represents the total number of boats built of a certain type, such as the Daysailer, up to that point. For example, our DS1 was built in 1961. Its hull number is 6555 and its class (or 'sail') number is 1001. It was the one thousand and first DS1 built to that point, yet it was the 6555th boat built by O'Day to that point.

The DAYSAILER was a collaboration of Uffa Fox & George O'Day. Fox designed the hull, but the original cuddy was designed & molded by O'Day & his company. The DAY SAILER has been built by several builders and with a number of changes along the way but the basic hull design has remained the same. The DAY SAILER II was introduced in 1971 as an ...
A typical hull identification number (HIN) consists of 12 letters and numbers, as in ABC12345D404. Here's what the letters and numbers mean: ABC: This is the U.S. Coast Guard-assigned manufacturer identification code (MIC). Go to the USCG Manufacturers Indentification page to access the Coast Guard's MIC database.
A boat hull identification number, which is commonly referred to as a HIN or hull ID, serves the same basic purpose as a vehicle serial number. It not only provides a unique vessel identifier, but facilitates tracking of manufacturer defects for recall purposes.

Hello! I'm the proud owner of a 1973 O' Day 23 footer. Is there a cross reference I can use to identify the model name of the boat using the hull number? Thanks Stan
Primary Hull Identification Number Location A Hull Identification Number (HIN) consists of 12 alphanumeric characters, providing essential information about your boat's manufacturer, the serial number, manufacturing month, and model year.
Hull Number Decoder. How to decode the meaning of a boat hull identification number. All boats manufactured for consumption within the United States after November 1, 1972 are required to have a twelve character hull identification number. Federal regulations specify that it must be formatted according to the elements shown below.
Centerboard weight = 52 lbs / 23.6 kg Displacement includes a crew weight of 640 lbs / 290.3 kg Minimum trailering weight = 1350 lbs / 612.35 kg
How do I read my HIN number on my boat? and how do I find the make, year and model of my boat using the Hull ID number? This handy guide shows you steps for decode your boat's HIN manually.
Prior to the 1972 start of the Hull Identification Number requirement, O'DAY used a set of 2 numbers to ID it's boats, each boat had 2 numbers, a HULL # and a CLASS#. HULL# refered to how many boats total had been built for/by O'DAY. CLASS# refered to how many of that class (in this case Day Sailer). the boa In question is Hull# 16470 and Class ...
One of the most successful of all O'Day models with more than 3000 built. A fractional rig was adopted after 1980 (as shown here). Available with keel/cb and fixed keel. (The version with a mashead rig listed here as O'DAY 22 MH)
Prior to that O'DAY used 2 Numbers to ID a boat, a HULL# and a CLASS#, Hull# referred to total O'DAY production, Class# referred to how many of that class. For instance, my 1970 O'DAY WIDGEON was Hull# 22698 Class# 1791, that means she was the 22698th boat built by or for O'DAY, and the 1791st Widgeon.
Don't run the risk of buying a used boat with costly hidden problems. A Hull Identification Number (HIN) lookup checks for accidents, hurricane damage, salvage, theft, registration, and title records.
