    Wondering how big a wheel would i need to move a boat that will weigh about 300lbs with everything in it. Looking to put paddle wheel on each side. 8ft x 2ft Any idea how big in diameter the wheel might need to be and how wade paddles?

    You need to post all the specifications, dimensions, etc. for the boat.

    BlueBell Ahhhhh...

    Any prop over 6" diameter will move it at 300 pounds gross.
    Why do you want to move it?

    I think he means a porting or beaching roller like some dinghies have under their transoms. It that is so, the real answer what do you expect to it roll on? If just concrete boat ramps, a narrow little plastic caster roller will suffice, but up a sand or rock beach you are going to need a bigger one or even a dolly of 2 wheels.

    No, he means paddle wheel.
    I looked at his posting history.
    And it sounds like the son of "michael smith".
    How old are you son?

    This ot'ta be fun to watch...<gets beer and popcorn>….Michael, there are reasons sidewheelers were obsolete 150 years ago. Anyway, how fast do you want to go? And how much torque and max rpm do you have? Those are the starting points. Vessel, wheel and float size fall out from there.

    Edit to add, There is a lot out there on the HPV forums about this, so you should read all that first.
