Here are some videos of Paravane 2 after it was balanced by cutting out part of the front of the 2 keels.
We had some trouble with seaweed:
More trouble with seaweed
Another nice run:
Using 3 lines to control angle better:
Using 3 lines again:
Just 2 lines, front and back, not bottom of keel. This can flip if I pull to hard. Catamarans have two stable positions and one is not good. Thinking about a monohull design.
The keels are trying to push up on the water a bit but the water off the far keel pushes on the bottom of the main body and lifts it up. I will probably try cutting down on the width of the center piece next.
