While playing Pickleball at Wheaton Recreation Center, received a call from Fred Alvarado. Fred was checking on his boat at Smith's. His boat is directly aft of Constance, on the hard there. Fred found the floor boards afloat. On his own initiative, he contacted the marina and obtained a pool pump (about 7" in diameter).
