It is one of the most valuable book to own as a sailor. Check out all the stuff on weather and sail trim. Sure, the skiffs have somewhat different control to affect the sailshape but the basic concept still do apply. I found it a valuable book all-around. Increasinly more so after each time I reread it or used it t look something up. It is not really a book that will grap you first time around, mostly you'll be reading over the important stuff the first time around, but it is there. Wouter

Unregistered | Hi David,
just remember to treat the speeds etc. he quotes for skiffs with healthy scepticism. <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" />
The cats have taken on his skiffs on their home turf, Sydney Flying Squadron for the last 2 years and Won. First year it was windy and the skiffs said try and beat us in light wind, second year light wind and cats won again <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" /> | | | Re: Bethwaite's High Performance Sailing

A yacht is a yacht, whether it's got two hulls or one. Certain principles apply to all yachts (lift, drag, resistance, righting moment, etc.), you'll just have to think a bit laterally to apply the ideas to cats. | | | Re: Bethwaite's High Performance Sailing

He notes the fact that displacement boats have hull speed limitations. They can't get beyond sailing in the "forced mode". It's got to be one of the most in-depth books on sailing ever written.

He also talks about the different sail shapes and the associated drag there. You do know his son, Julian, designed the 49'r Olympic skiff, right?
I wish someone with credentials would write a similar book dealing only with catamarans, hull shapes, rig lift/drag, maybe throw in some lift stuff for designing hydrofoil cats and tri's, etc.
And Rick should update his previouse excellent book, Catamaran Racing for the 90's, to Catamaran Racing for the 2010's and beyond! To include A cats and all spinnaker cats, Corsair Tri's, and the new Lightspeed cat and the R33.
We have seen much development in the past 10 years and need new books to keep up with it.

Unregistered | I had a heck of a time tracking this one down. Pretty much every online store claims to have it, but after they drag it out a month, it becomes clear most don’t. I got lucky and finely found a copy. Well worth the .5 My version is a 2003 reprint and it is not clear if it has been updated since 1993. | | | Re: Bethwaite's High Performance Sailing

Rick does a SUPER job, but i would like to see his knowledge applied to these new boats. I am seriously looking at a Blade.in 2008 Doug and Ashleigh Snell | | | Re: Bethwaite's High Performance Sailing
