help me much. Thanks for the offer though.
Part of the problem is that I'm not sure what engine was supposed to go
in these boats originally. Typical small sizes (3hp) were often cast
iron, two stroke, make-n-break ignition. Above twenty horsepower they
were often small marine four cylinder equipped from Grey marine or
Redwing, etc. What were the in between marine motors like? A ten horse
make-n-break is heavy. That could weigh as much as the hull! I would
suppose the hull to be around 300-400lbs. This makes estimating the
weight to horsepower difficult.
I would think the tunnel would force the bow down in acceleration like
on Mr. Whites RM. The jet of water from the tunnel would pull the water
from transom and make it difficult to tell when she would be on plane.
This design is right at the threshhold of a semi-planing boat. The
concern is that she might not perform well unless very lightly loaded.
If fuel mileage in this day were not a concern I would build a Little
