Yes ofcourse that's a good advice. Problem is only that I don't have a fixed camara supportdevice. I'm more or less forced to use a helmet camera.

My cat is 15 ft. and 2.5m large; the tramp surface is too small for having extra things in the way.

I have already trouble with my bag for food and drink and for the extra ropes with which I can pull my rudders down from the high-side.

Building a camara support on the side of the hulls is also not possible because of the waves in which I use to sail.

Especially the last impossibility hurts because only with such a camera position I should be able to film the incoming waves as I see them by myself.
