: So was too skittish to put hatches on my first Guillemot but am now
: wishing I had done so. Would also like to install a skeg to help
: with tracking and having hatch access would work. Does anyone
: have suggestions for how to install hatches after the boat is
: done?

I do all my hatches after the deck is attached.

I glue up a pair of ply rings over the cutout to get the shape, you can do this on the outside of the deck.
