Etienne-Thanks for the links; didn't work when I clicked either of them; Computers screwing with me big time of late.Try again? Beautiful boat, by the way; not to worry about the rocker adversely affecting speed; the North Star goes like a scalded dog.It has that nearly impossible combination of speed and maneuverability. Plus, the final stability is not to be believed. The Aleuts really knew their stuff, as does Rob Macks. You're gonna dig it. Thanks.-Greg
