Re: Should I consider a Toon?
If you are trying to stay in your budget, looking for a solid platform (toon/deck/fence) and power (outboard), would be the best target for the funds.
Getting more speed with boats and with pontoons especially, can be a rich mans game. It is reasonable to spend your money and get something that will hit the low to mid 20's. To get it beyond there it gets much more expensive for less and less gain.
I would look for a 2-toon unit with the largest toons you can get and a 90-120hp class out board. They will run at around 9-12 gallons per hour at WOT. If you jump to the 150 class, you will burn more gas and the gain, based on a non-planing hull will give you marginal speed increases.
For tubing, 24-25 is the fastest you want to go anyway. With smaller kids, much less.
I just sold this spring a 1992 25 foot 2 toon with 1989 90hp Nissan for $5200. The deck and furniture was functional but needed a rebuild. Just for comparison.
