Hull number - TRJ number
The TRJ (Coast Guard certification number) is found on the starboard side of the transom just above the swim deck if she has a one. This would be true of all fiberglass Trojan hulls 1970 - 1992. TRJ stands for TROJAN and this is the Coast Guard certification number and the one that is often found on your registration.
The Hull number or as is some time referred to the (working hull number) is found on a tag made of aluminum by the AC DC panel, inside the door of the AC DC panel or below the AC DC panel. On some smaller Trojan under 30 ft it is often found on the back of the head door or a closet door.
On the F 30 Clean Machine it is on the inside of the closet door starboard side forward.
This Trojan tag has the engine ID number (s), inspector number and the Hull number which is three numbers followed by four. This number is its finger print of your Trojan and is the easiest to work with or decode.
The first three numbers are the model of you Trojan 321 is a F 32 Sedan, 251 is a F 25, 210 is a 25 foot Sea Raider 309 is a 30 foot Sea Raider 301 is a F 30, 440 is a F 36 TriCabin, 460 is a F 36 Sedan, 500 is a 42 MY.
The fourth number or first number in the second set is the year. Hull number 321 7045 = F 32 year 1977 second set of three is its production number in this sample 045 is the 45 F 32 built since production started in 1970.
The problem with with the working hull number is that on large production boats like the F 32 some times the production numbering started over. So if you do not know if your Trojan was was build in the 70 or 80 then you would need the TRJ number as well to know if the 7 was 1977 or 1987
If you have a wooden Trojan 1945 - 1969 then she would only have a Trojan tag as described above or before 1955 she may only have the three number followed by four stamped inside of the transom, the engine stringers inside of the engine hatch.
