Hull Identification Numbers

 

Pearson Serial numbers

The information below was taken from Dan Pfeiffer's wonderful Pearsoninfo.net site and other information sources.

I have seen a lot of questions regarding the meaning of the coding in the Pearson serial numbers. I don't know if this applies to all Pearsons but I think it is correct for boats after about 1973.

The hull identification number (HIN) is required by the USCG to be displayed on all recreational boats built after October 31, 1972. The number consists of a combination of 12 letters and numbers identifying the manufacture, the model number, hull number and date of construction and model year.

Hull numbers used between October 31, 1972 and August 1, 1984 are as follows

                        1 2 3            =    Hull Manufacture's Code
                        4 5              =    Model Number
                        6 7 8            =    Hull Number
                        9 10 11 12    =    Date of Manufacture (9 10 are for the Month, 11 12 are for the Year)

                                OR

                        9                 =     M
                        10 11           =     Model Year
                        12               =     Month of Manufacture; A = August, B = September .....

Hull Numbers after August 1, 1984 are as follows:

                        1 2 3            =    Hull Manufacture's Code
                        4 5 6 7 8       =    Manufacture's Hull Number
                        9 10             =    Date of Certification or Manufacture (9 is a letter for the
                                                Month; A = January, 10 is the last digit of the Year)
                        11 12            =    Model Year



                                     

Manufacturer
This is the name of the manufacturer of the boat. PEA is for Pearson.

Model Number
This is the manufacturer's model number designation. 46 is the number for the P26.

----------------------------------

*Pearson built a line of boats called Triton Yachts by Pearson in the 1980's. Molds were from Bayliner and were previously marketed as US Yachts.

If the model number of your Pearson is not listed here please send it to me and I will add it.

Hull Number
This is the sequential number of the hull. This is a bit confusing because there are only three digits. For P26's after 1,000 the sequence starts over and you have to add 1,000 to the number given. P26 hull 1,000 was built in 1975.

Model Year
This is the model year of the boat. It is not necessarily the production year. The model year runs from August of the previous year to July of the year given. I don't know what the M is for.

Build Month
This is the month of the model year the boat was built. It starts with A for August and runs to L for July alphabetically.

A August       E December    I April
B September    F January     J May
C October      G February    K June
D November     H March       L July

                                       

Sea Dragons HIN PEA69008M81I:
        Manufacture: PEA ---- Pearson
        Model:  69 ---- 36 Cutter
        Hull Number: 008
        Mode Year: M81
        Build Month: I ---- April

The Builder's Plate is located below the companionway and shows the Builders name and location, as well as the hull number for that model.

                                    

Some P26s have been reported to use the number for the build month and the actual build year instead of the model year. December of 1973 (1974 model year) is shown as 1273.

All this means the boat with SN PEA46205M76A is a Pearson 26 (model # 46), hull number 1205 (205 + 1000) made in August of 1975 (the start of the 1976 model year). I guess this also means that if P26 #205 was built in August of 1970 (a guess) it would have the SN PEA46205M71A or something close to that. Almost the same except for the model year.
