Cheers, Nels

Is it still a "centerboard" if it lifts straight up instead of
pivoting - because that seems to be what is drawn...

Peter,
Nice link! I haven't seen that type before but always assumed that
Bolger was refering a more pronounce"L" shaped board,like seen in
some of George Holmes canoe yawls(sorry no link) whereby the vertical
leg of the "L" served as a lever arm and the base of the "L" was the
part immersed underwater.These centerboards or centerplates were also
usually made out of a large piece of iron and I am sure contributed
somewhat to the overall ballast.

Just my thinking about what Bolger may have been refrencing.

Sincerely,

Peter Lenihan

In the discussion of one of his boats, PCB mentions that many of the
original Humber yawls had L-shaped centerboards, far foreward.
Perhaps this picture illustrates what he was taking about.
