Most efficient hull shape?

What is the most efficient hull shape, considering a small sailracer?

 

Straight line only? How important is stability? Turning? Weight displacement? There is no clear cut answer as other things come into play other than just the most efficent hull shape.

 

If you are intersted in the fun of racing , you may want to decide on a class. Match racing is the true test of skillls.
It will take a while to master the quirks of whatever Class of Boat you choose, and you can have fun experimenting with tuning and polishing your skills.

 

Purpose: One person, no comfort (low stability) and low displ.
Easy to build and hull material should be plywood

What Im interested in is what shape of hull you should work with.
What different types of hull may fit this purpose?

/Thanks!

 

The fastest hull shape is the one which does not come in contact with the water.

Start looking up foil sailers.

 

There isn't a "fastest shape", just a difficult set of design compromises that the designer has accepted, as a net result of client desires, during the design process.

If interested in all out performance, in a light weight, small sailboat, then try a Moth foiler. 20 knots is pretty routine, with blasts to 30 occasionally.

If you don't like the idea of "flying" a boat, then a Swift Solo will get your heart pumping.
