Daggerboard - use of?

   These folk claim that multihulls which can't handle the 

shedloads of wind but can do three times wind speed as opposed to not 

much more than one times are far more efficient than boards. Frankly 

that's ****, and I suspect you would agree. 

Now extrapolate the logic...

Well as it happens, I've got a part built mini cat in the shed right now, I'm 

hoping to improve on the efficiency ratio a bit further up the wind scale.

Now you're entering a whole world of theory of how to go fast(er)

Windsurfers can get twice windspeed, they have their moments..

But having come quite close to Cats in that round island race, I have to 

accept they're fast, it's down to the wide footprint to hold the (big)rig up 

there, and the well reduced wetted area particularly when they fly a hull.

Now this is going right off topic, I'm in the closing stages of my speed cat 

board thing, I'll bung some pics up when it's finished, I'm also trying to 

get a special paint surface made from a powdered hydrophillic compound 

to coat the under hull surface with.

 So we could do the Cat discussion on that thread as and when I start it.
