Trojan Hull numbering and TRJ Numbering

[BeaconMarineBob]

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.

Thanks for the info Bob.

In your example,

"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. "

My F32 is a 1985 model with hull number as 321-5016. Can't imagine this is only the 16th F32 produce since 1970...or do you mean the 16th F32 of the production year?

Thanks.

Another example: My 1972 Tri-Cabin's hull number is 4402763. The '440' is the model designation and the '2' represents the model year... in this case 1972. The last set of numbers confuses me because I can't believe Trojan had produced 763 Tri-Cabins (Sea Raiders & 'F-boats') in the first three years of production.

For comparison, Chris Craft's competing 35' Double Cabin achieved only 386 hulls after it's first five years of production from 1973-1977.

I emailed Bob to see if he could shed some light on that first number after the year designation.

Mine is a '67 36 sea voyager express hull # 95-7015 on the plate under the dash & stamped in the keel.

All,

"TROJAN TRANSOM NUMBERING SYSTEM" question/clarification:

The guy from whom I purchased my Trojan F36 swears that the make/model is a F36 1979.

Am I reading the Transom numbers wrong?

TRJ R 0 503 1179

TRJ = Trojan ID
R = "I have no Idea."
0 = Model year is 1980? <-- "not a 1979 like he says?"
503 = 503 F36's built in 1980?
1179= Month and Year of certification: November 1979?

I used this as a guide: http://www.trojanboats.net/trojan-numbering-70-87.pdf

Am I decoding properly? Is it a model 1979 or Model 1980 F36 Convertible?

It could be a 1980 model built in late 1979 . Bob at Beacon can help you with that . If documented the CG likes to go by build date

My F36 was built in late 77 , it is a 78 model . And when it was registered with the state it was a 1978 . However when I returned it to U.S.C.G. Documentation the CG papers say 1977 . They go by the completion date of the boat . Its confusing yes but the way it is . Your insurance likely wil go by what every the registration says .

Are you Documented or state reg.?

I registered the boat today. State registration shows 1980.

Hi all. New to the forum. Would I be correct in saying that Hull Number 210-3249 would be a 1973 25 ft Sea Raider?
