Unfortunately we do not have a 96 catalog but.....
We do have both the 95 and 97 so bracketing your craft is a start.
97
95 (spec page all models)
You'll notice (kinda hard to read
) the 97 shows 102 gals. and the 95 100 gals.
This is +/- anyway. Tank manufacturers list the size on the tank and it varies from year to year due to manufacturer I guess. My 91 is listed with a 100 gals. but when I removed it, the manufacturer tag listed it at 105 gals.
I'd say, as Delta D stated above that 102 gal. is a good estimate.
Look close and you'll see the specs between the models are about the same. I'd guess the dry weight of the 95 does not include the motor/rigging where the 97 does. Draft is a few inches different between models but these aren't designed for "flats fishing" so that's not real important. I'd say these pretty much match your 96.
Good luck.
