- May 1, 2008Hi Chris -
The Martha Jane (revised) makes a nice low-powered camper -- 8HP pushes it nicely. You
get the amenities of the Outboard Cruiser and Cabin Clam skiff and still keep under 9.9.
I'd say go ahead and try your 5HP on it first - it might be enough too.
Most of my boating is on local lakes where the wind is too flakey to sail. I use the MJ
mostly as a powerboat.
Food for thought since the MJ is already a finished and tested design.
I have some YouTube footage showing some testing with a small (not the power thrust)
8HP Honda 4-stroke. I don't even have the leeboards or mast on it yet - or the rudder yet
for that matter. Or paint on the transom (or the doors built...) If you want to see it, go to
Once there, click on Bolger Martha Jane Motor Test Run. The engine sounds and
comments you hear are from the chase boat/photographer. The Honda is not very loud at
Using the power thrust 8 instead of the one in the video, I can push the loaded boat just a
bit over 6knots, but the motor is working. Cruising / no wake speed is about 4.5 knots
and the engine is quiet and happy at that speed.
