Sometime after 88 noticed a lot of boat mfg's added molded or bolt on platforms. Heard it was a law passed. Figured it was pushed to get more money out of your pocket when renting a slip. My 83 is 33' but bolton platform added close to 35.5 now. Sinc its listed as a 33 thats what is charged for. My 88 Seebold 235 with factory bolt on made it about 25' caharged as 23.5', my Sunsation Aggressor 25' but only 23.5' w/o platform charged for a 25' boat. Thinking I remember 89 and beyound boats were affected.

I was looking at some 28' Checkmates at one time bolt on platforms not included older used ones. Looked at new ones same boat became a 30'er

That "Fountain" tape measure comes with 5 lbs of costume jewelry chains......

If I remember right, it's been a few years, 25' Active Thunder was 24' 8", not including bolt on platform, with tape measure.

my marina doesn't care they drop a rope off the front and measure to the furthest point in the back. Either swim platform or drives in up position.

Do not forget the black hair die!

1990 Baja Sport 250ES - 1991 Baja Sport 270ES - Same exact Hull, so I guess 1991 started to include molded in swim platform as length of hull.

Ayuh,.... In what I've found of hull model numbers, in general, of a 3 digit model number, the length is somewhere 'bout the length, in feet, is the 1st 2 digits,.... within a couple feet,...
The 3rd digit is more likely a sub-model number, rather than inches, like outboard, vs; an I/O equiped,... 190, vs; a 195 say,...

As for the Actual length of any hull, a tape measure is the only way to know for Sure,...
What's measured, 'n included or not, depends on who's measurin', 'n why they're measurin',.... ;)

I was trying to figure out what models I need to be looking at. I want a boat big enough to take rough water and yet be around 70 mph with a single engine. Which might be like finding a unicorn?
thanks RB
