TOPIC: What model boat is this?

Not sure if it's a glassic but I'm interested in it. It's 15ft, and I would like to know the transom HP rating.

my 15' bow rider is rated for 100hp its a 1977 Arrowglass
The make and rating should be located on the CG tag inside the boat.
If you find out make and model, you can look info up at iboats.com

Something I have discovered is the open bows usually have higher HP ratings than closed bow, guessing to the extra weight up front, and able to have passengers up front.

It looks like a Galaxy or a Larson?
100 HP is likely very close.
My Starcraft 17' Tri Hull is rated at 110 HP.
You really never want to go to fast in one anyway.
All your fillings will work loose and the rest of you will be in pain after a few minute ride.

I think the perceived or real extra HP rating is likely due to the fact it would be difficult to flip one of these tri-hulls.

jim good description...on the ride...i thought about re-powering mine with 85hp, but with the 50hp I can go 30mph and not loose my filling..
