Another chemist at my lab built one of these wooden H-like things on the next street over, after Roger Maris's widow sold him the house. Phil asked my advice (I said NOT) and offered sail lessons at no cost of course on my Hobie 16. He declined, building it with his teenager son. I saw it in the driveway for 3 years, and it never moved, never got mast or sails. Too bad. Lead the horse to the water----
