A possible Skimmer-boat?

Hey, who are you calling dork here? obviously you are the dork here since you just insult people for no reason , all I wanted to discuss was an airboat with somewhat lower friction and withouta second lifting engine, without having a surface piercing air propeller.... so there is really no need for being rude here and now really

 

Maths is not an exact science,but just a theory,or a simple guess.You can be very selective with theory and forget about practice.Maths will have to give way to results in practice.Many surface-piercing props can run up to 20.000 RPM. A four foot fan can move hundreds of cubic air a minute running at 1400 RPM.It is easy to dispute ideas that one is not familular with,if you do not take the time to check the field of experienced past creations.

 

if you Google search Images/ airboat plans or airboat fans you should get a lot of ideas.

 

A possible skimmer boat

This cooling tower fan should make a cheap airboat fan for a home handy man.You can set the pitch of the blades to suit uour self.Easy to ballance and easy to fit to an air boat as parts are already made.

 

One thing you can do is run an external stringer down each side of the bottom. The outer edge of the stringer will aid steering while the inside of the stringer will catch the air bubbles which run up under the bow. a stepped hull will also help.

 

Hi. You might want to check out "hydrocopter" on this list and on google. Reverses the liabilities of water friction and uses water friction to keep the boat afloat and propel it forward.
