Re: [Paddlewise] question on hull speed

Rafael,

There is an organization in the Puget Sound area that has rated kayaks for a
long time. Look at
http://www.soundrowers.org and check on their boat classes. They have
divided kayaks into three basic classifications: Sea Kayak (SK), Fast Sea
Kayak (FSK) and High Performance Kayak (HPK) and use the L:W ratio. I don't
know how they do any handicaps, but I think it's all on their web page.

Of course, there are bound to be kayaks where you are that don't have a
presence in the Puget Sound area but you might be able to find some
references... and if not at least use the L:W ratio yourself.

Matt Broze is the guy to talk to about this.
