Ok so I have a Catalina 25 1985 the previous owner removed the thru hull fittings for the original sink icebox drain (port side under stove) as well as the fitting in the bow that brought in salt water for the head (locasted under the v berth) . All was refiberglassed at boat yard, ( beautiful job) The result though is now there is no way for sink or ice box to drain out of boat. Is there a way or has anyone, installed a simple thu hull fitting thru the hull above the water line to allow for the sink to drain out and or the ice box?? The only thru hull remiaing is on the port side allowing for the head to dump out of the holding tank to the sea.
