I have a sit on top and last year rolled it when the hatch came a little loose and it filled 80% with water. I was glad I had headed back to shore and was only 10 meters from dry land.
I would like to put in an eletric bailer and have scouted most pieces. The only thing I think I need is the part where the tube from the pump runs into it from the bottom and the piece is glued / secured to the deck and provides the "spout" for the water to flow over the edge of the kayak. (Not my best desciption.)
Any and all advice for a source appreciated.
