: Hi folks.
: I am at the hatch stage on my woodstrip sea kayak and would like to keep the
: hatch cover as flush with the deck as I can.
: I intend to install a plywood ring under the opening, which will project out
: 1", so that the cut-out will sit on it, thus staying flush.
: How do I seal the hatch when it is finished?
