Been watching this thread for a while, had an interesting thought........
Both the NSS and Surfgate look to be based around the idea of trim tabs mounted off the hull sides at the transom
Surf gate is very similar to a set of lenco/bennet trim tabs mounted vertically
The NSS is very similar theory to the ql trim tabs by Volvo penta, again mounted vertically
Trim tabs have been around for nearly as long as powerboats, is it all of a sudden possible to patent where you can and can't mount them?
