be on most baidarkas) as the final straw that led to this surgery was when I
got locked into a trough during a spring squall in Canada and could not turn
her downwind to save me. Literally. I also think the additional rocker has
added greatly to her stability, helping accomplish the other goal of this
rebuild. >>
Presumably that increase in stability is the result of the ends of the boat
being higher now (due to the increased rocker), decreasing buoyancy there,
which is compensated by a deeper draft amidships where therefore more of the
hull (now also more flared) is immersed, creating a greater waterline beam,
hence greater stability?!?
