I just bought a 1975 Catalina 22. Three days after putting it in the water and sailing it for a few hours, there was a small amount of water in the bottom of 3 of the storage compartments (an inch or less, no water had come in thur the deck/cabin). Is this normal? Where does the water come from since there were no thru the hull fittings visible when the boat was on the trailer? The previous owner had stored the boat on land, we will keeping it in a slip. Thanks.
