Ok. The number of passengers equals the number of seats. I can calculate that. What about weight? My dealier says in the Speedster 150 (enhanced engine) 'don't worry, it won't sink.' My wife, two neighbors and I weigh out at an estimated 975 lbs. That amount would be in addition to fuel, PFD's, drinking water, fire extinguisher, anchor etc.

I am not looking to go at top speed but would there be damage if I cruised around at say 20-25?

Thanks,
