Find a used one, there are some great deals out there. You may have to drive a good distance to find the right one, but 20 grand will buy a hell of a used boat
+ 1 for the 90hp or bigger motor if you plan to ski/tube.
As a owner of the boat your interested, in let me tell you. It gets real crowded with 8 people aboard and a 60 will be way too small to tube with. Don't even think about skiing. It's a great boat but not for what your intending to use it for.
So i need a mid to large size tri-hull. Any recommendations for 25-30k?
Actually Tri-toon is a patented term used by JC pontoons that is now used to classify all triple pontoon boats much like Kleenex is used by some for all tissues. From what I understand the "proper" term is triple toon or triple tube.
I have the exact boat, a party barge 21, but i have a 90 ELPTO, I get 26mph(gps) with 2 people on board, and have no problem wake boarding behind the boat with 5 or 6 passengers.
EDIT: fly typical speeds for skiiing is 25mph and wake boarding is 16-20
which is much slower than many people THINK is needed.
