I’ve been paddling my Petrel SG for about 7 months now and am sincerely disappointed in the rear hatch, which lets in a significant amount of water in only mildly lumpy conditions.
This is the 17-1/4" x 10" oval hatch. The hatch rim is seated well in the Petrel’s recessed hatch ring, and neither it nor the hatch itself have mars that might compromise the seal. Since observing the issue I’ve been careful to align hatch and ring arrows when sealing the hatch, with no improvement.
I’ve contacted Sea-Lect about this and am also posting here to see if others have experienced this issue and / or know of a resolution. I’ve heard nothing but great things about this system and while nothing can be guaranteed waterproof, this particular hatch lets enough water in while surfing or in lumpy water to actually affect the boat’s stability.
