Hmm... I did not expect that the weight of a cell phone would make a significant difference in the sailor’s ability to righten a cat... (Sorry could not restrain myself)
I think that practice proper techniques and suitable equipment (solo right, righting pole, water bucket, shroud release) and the skills necessary to use the stuff are the way to go. I guess what I like about this forum is the discussion and user feedback in context with stuff that works. Since the solo right might not be available at this point, I will try to build a similar device based on a defective windsurfing mast. In case it works I will post my experience and some pics of the thing. I do not like the cell phone idea. A cell phone or better a radio should be the last resort - when every thing else fails. Having one available is not a bad idea. At the same time it might provide a faulty sense of security.
