more thrust, more efficient, at lower rpm's , now we're talking, just need to match the motor, Batt Manage Sys, , Genset. hopefully , the result is hull speed for hours, reduced fuel consumption under Batt Power, this vessel has 1000 gallon tank, diesel predicted to go to $4 plus soon, the ROI is there.

This is a sailing vessel, but let's assume the average motor distance might be 10 miles in a day.

The major advantage to running a larger prop is more usable out put at a slower rpm which makes for less turbulence in the water. less cavitation etc

Thanks Nicholas,

Awesome video. Nothing wrong with needing to be convinced, Im the same way.

Im going to look into what a 48" prop, e-hybrid solution will produce on this hull.

Best Regards

It has a 30" Maxi full feathering prop on it right now, Im trying to keep it, #1 because its expensive, but also because it drives to boat at 10+ knots, Also it allows the boat to sail sans prop drag, after all the boat is a sail boat.....I will need to be convinced that the electric motors will need a larger prop to do the same speed. I realize that electric motors have more usable torque, but it should just make this prop function better than running it with an ICE, but to answer your question I could fit a 48" prop on to it If I so desired and found one...

You can see a video of the hull, this is the previous owners ex-husband... http://vimeo.com/9893480
