would you not get a speed increase from the slot effect if you but the control sail to within a couple of mm of the leech of the main? what made you decide to change the configuration from the first video?

If it was made as a slot. It would not control the angle of attack very well. The problem with the first one was that there was no way to park it "switch it off".

This would be a lot of fun in Florida's shallow grassy lakes that hang up keels and rudders. It would slide right over. I want to build one!

Hi

Seems to be slight misunderstanding here. These models are not operating without rudders. There is rudder under each hull at the rear.

thank you!ever try aFliptacker? check out Maltese Falcon yacht +DynaRig.very responsive boat ,going bigger?

[ZKMX7]

I have considered the Fliptacker principle. Personally, I don't think its worth the trouble, the loss with a symetrical section is small compared to the complication of tipover technology.

Maltese Falcon, DynaRig. These ideas are simply not radical enough - just improvements on 17th Century design. Why use complicated computers for wind-alignment when a simple wind-vane will do the same job.

Very good idea of wingsailing ship

Any solar to keep the battery charged?

a self adjusting sail sure would be handy in light variable winds. so the sail has no servo? i want to build a sail like that for my cat model and possibly for my hobie 18. how does the flap controll the trim? how would i depower something like that. you should make another video explaining the sail close up
