Scarab 22 trimaran with E Propulsion Navy 3.0 and E 60 batteries.

Testing out the E Propulsion Navy 3.0 outboard and the three E 60 batteries on a Scarab 22 trimaran.
In the video I am doing some mental math checks on the system because the controller tends to show 99.9 miles of range at low speeds and then jumps down to 50 miles and less as I accelerate, so to make sure the numbers make sense I am dividing battery capacity at full charge of 9000 watts by the watts being drawn at that speed to get the run time and then multiplying run time by speed to get the range.
I did run a test at 500 watts twice but one of the videos did not record. The results were the same.

Why not suspend the flexible solar panels, like trampolines between the rear of the floats and hull, behind the aft arms? Leave the Tramps clear. Your power vs speed curves are very impressive. My 4.5m sailing dinghy, uses around 200-250 watts to go 3 knots.

Good Idea I will look at putting solar there to see how I might do it. I agree on the power vs speed. I have been pleasantly surprised also. I think the long and narrow hull helps. This boat is also really light for it's size.

I just uploaded another video of a 20NM trip on a calm day. 20NM average speed 4.7 knots, I used just over 3kw.
