Over the weekend I glassed the deck, and last night I cut out the openings in the deck for the hatch covers. Tonight, I clamped on the supports for the rear hatch cover and the coaming rim and spacers (see photo). The coaming rim used all of the bar clamps and c-clamps I have totaling 23 clamps . . . most are borrowed. I also used 16 spring clamps to keep the hatch cover supports in place.
