Actually that is not far from the way it is supposed to work. Here
is an article that describes how the variable drag design works. While sailing and using it as a droque, it is perfect, it doesn't spin or break the surface, but I have never tried to deploy one as a sea anchor, so you may be right. It is SOLAS approved as a 'compliant sea anchor' which is why a number of offshore racers and cruisers carry them I'm sure.
Since I try to avoid extreme conditions in my current boat, my primary interest is for an emergency steering device and drogue, but I have yet to use it for anything on Boomarang. I hope I never have to. I will rig it to see how effective it is though, just to know what I can expect if the time ever arises. Besides, if I ever need a tow, I might be better prepared there too.
Thanks for your thoughts.
