Hi, if you''re going to go to that much trouble why dont you mount them to the deck as well as the bulwarks, keep the stainless and do the job right so that it doesn''t leak??????????????or instead of going to that much trouble to install a hazard, just leave those pesky little suckers near the dumpster and see how long they lastAnd in lieu of aluminum check out that new material they''re making front
wheels for bicycles out of, y''know the stuff?....when they fall and twist up the
wheel they just get down on the street and put the
wheel between their legs and twist it back to true. So when someone does fall over board, or puts any weight at all on your new clever stanchion installation, and bends it all out of shape you can impress everyone with the ease of re-straightening......something the Stainless tube industry will be horrified to see!!!!
