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
