Hi Tony BEST of the season you ya. The "drains" you speak of are 2 factory "scuppers" on either side of the cockpit side deck. I noticed #50 has different cabinetry above both settees also. Could it be the early production models had things that were later dropped ?? The drain at the base of the keel was owner installed , I presume to allow any deck leak water to run out during storage. The decks are now re-cored and everything re-bedded so NO MORE LEAKS!I will post pics of the cabinetry when I figure out how to get pics posted. take care Frank
