The Hobie 8 in. Twist and Seal Hatch is the standard hatch on Hobie kayaks. Older models can easily upgrade to the twist and seal. The twist and seal is a unique mechanism that allows for one hand operation and it ensures that the hatch is sealed. The hinged lid keeps the hatch lid with the kayak at all times and the rubber gasket keeps the hatch dry.
I bought the 8" flat Hobie Hatch and mounted it to my curved Perception. I knew they would not match, so I snugged the hatch down about half way and started heating the kayak with a heat gun. Slowly for about 30 minutes, I circled the heat gun around the hatch. When the kayak was soft enough, I placed a weight on the hatch to form both surfaces together. What a beautiful job, as the kayak formed perfectly to the hatch. I could not ask for better results!! If you do this, the secret is patients and slowly heat the kayak....
If you are thinking of purchasing this hatch for a Hobie Kona, go for the 6" hatch. You can get it with a dry bag that is not available with the 8" hatch. This hatch works well but, barely fits on the kona.
buenisimo el producto y el cervicio
Had more trouble finding SS screws than I had with the installation. I must say it is a leap of faith the cut a eight inch hole in your new boat.
