I haven't spent much time in the shop lately, but have made some progress with the deck.
Hatch and coaming recesses were done 'in the usual way' with foam sacrificial forms, glassed over from the underside.

Here's a pic of the hatch recess foam, filleted in place. The contrasting color gives a visual cue later when grinding down the deck to meet the recess.

Cutting foam for circular hatch recesses is easy with a quick circle guide. For the oval hatches on this build, I made a pattern on doorskin and then cut the foam using a short 'pattern follower' fence on the bandsaw.

For cutting, the foam was impaled on a few staples driven through the doorskin pattern. The pattern rode on the 'fence'.

On this build I tried using cheaper white expanded polystyrene insulation foam board for the hatch recesses, since my local outlet didn't have the pink board in the thickness I wanted. I wouldn't do that again- the white board has a very coarse texture and doesn't machine as well as the pink OwensCorning extruded polystyrene board.
