The current WoodenBoat magazine cover story is
about the 21' Handy Billy. It is a semi-displacement
hull, a very efficient form. Semi displacements have a
higher operating speed range than displacements and are
still energy efficient. They don't have the 'power
hump' associated with planing boats. Semi's will slowly
come up to skimming, and if enough power, planing.
This one looks like a good hull shape for someone
interested in a medium size, moderately fast electric.
Although it would move along nicely with 2Hp, the Lynch
motor would really make it scoot around. The hull is
shown planked, but the form would be easy to make in
stich 'n glue plywood. Take a look!
