G'Day Dave, Thanks for the clear description and the opinion on whether it was initial or secondary stability. On reflection I think you are probably right for the Pittarak which has a fairly smooth transition between initial and secondary stability, but I'm not sure about the hard chined boat. I started drawing cross section diagrams from memory of the chined hull and was trying to remember the range of angles of the sea surface from horizontal in 1 to 1.5m rebound waves! If they are as much as 30 degrees then surely most chined boats would have to be edged beyond their point of initial stability? I'll maybe take a hemispherical spirit level with me next time! All the best, PeterO *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
