The Bow Hatch is secured in place with four Camloc fittings and sealed with a Gasket. All went well except I realized that my kit did not include the Gasket. I searched the kit inventory list and it is not there... why? I even checked the 'old' manual and it refers to the Gasket. Oh well, I am sure I can find something suitable to use in a marine supply store. If I need to order something else later (perhaps the Dash Cover Upholstery?) from Progressive Aerodyne I might complain that the Gasket should have been included and throw myself on their mercy (they have been receptive before). 9 August update: I did end up ordering the Gasket from PA and installed it without difficulty
