I have placed posts in the other forums, and for the second time here, hopefully some one here will reply, there is a plug or cover in the bottom of each of my Strider Clubs hulls, 4-6 inches in dia. could someone tell me what these are for? One has a small amount of water in it's hold, the other is dry, I know the club has keels under it, do these openings go into the keels, I do not want to mess with the leaking one, for fear of sinking the boat, I have no way at present to lift the boat out of the water, my next idea is to beach it and then see what happens if I try to open up this plug or cover, any help will be greatly appreciated, thanx, Dave Goodrode, Kissimmee,FL
