Here's another idea for a support. Take a 2x4 that is two feet longer than needed. Cut it in half, and put in a shollow notch in one end. Stand the two pieces up, over lapping them, under the bow with the notch around the bow. Clamp or screw the overlap together with enough screws to handle any weight that might accummulate on the top. Might want to put a square of plywood under the pole to protect the deck. Nifty, quick and no tedious measurements. Now Myrna, when you get finished with all this sawing and screwing, make sure that Bob pours you a nice drink! Rudy Briney Bug, Panama City, Fl
