for the first time since owning my Abbott22 I get water in the bilge when it rains. I have tarped over the cabintop, hatch and companionway but the same about of water shows up when there is an average rainfall. I know its not he keel because the this also happened in the winter when the boat is out of water. Deck has no corruptions. Cannot find traces under the storage spaces. any suggestion how to test ? Maybe hose it and have someone inside looking in any suspect places ?
