Re: Pontoon Size
Brandt, you did not mention the lake environment that you operate in. For instance many boaters are on protected damed up rivers which tend to be a whole lot more calm than the Texas lakes we frequent here. If you have never tried to load a large pontoon on a public ramp that is located on open water, it's a real trip. All spring we had 15 to 30mph cross winds at the ramp. That experience is not for a novice. It can be a two-man job. It's that kind of consideration that one might think about when buying a pontoon larger than what is need for your intended purpose.
Our extended family wants to swim, ski, tube, and knee-board. Fuel consumption is not an issue if you motor out to friends, tie-up and party and swim. But for the sports that require you to be on and off the throttle all afternoon, the cost of operation is exponentially greater the bigger the rig and motor. Example- a new HPDI 225Yamaha 2 stroke eats upwards of 8 gallons a running hour at higher rpm's. Gas is $4/gallon in Texas marinas. Mixing oil is $22/gallon. Ringfree additive (recommended by Yamaha) is $26 pint. So 4 hours can run upwards of $150 for a fun active day on the lake. Another reason I say consider carefully what your intended use is when upsizing.
Again if running out on the lake and tieing up with friends is the mission, fuel consumption is not a big issue.
