Hi Peter, I built Cleopatra when it was first publihed as a plan in
Model Maker some 40+ years ago. I increased the hull depth slightly
for greated displacement and water grip. Also increased the height of
the coaming inside the superstructure. I found that using the lay
shaft and pulleys as per plan caused too much friction and power loss
and if building it again, I would use a motor and gearbox belt
driving directly onto the paddle shaft. mount the motor above deck
level with the belt angled down to the paddle shaft. All the best,
Walter.
