When considering a hull for electric, keep in
mind that early power boat designers faced the same
problems that EB designers face now--low power and high
weight. The Handy Billy is based on a William Hand design
from 1912 and would indeed make a nice electric
boat--other designs to look at are the boats from William and
John Atkin, the plans for which were published in
MotorBoating Magazine during the 1930-50s, maybe even earlier.
Just because a design is old, don't dismiss it for
being outdated and irrelevent--I'll take the practical
experience and common sense of those early designers over a
computer program anyday.
