Hi Kirk, I'd be interested to know how you reinforced the grid. The yard that repaired my 27 after the PO tried to rip the keel off did a shoddy job that I spent a lot of time on. The grid crosses the bilge box in two places And is in the shape of a flanged C channel with the flat part up serving as a place to screw the floor down to. The yard sliced off one of the sides of the channel in two spots over the bilge producing a weakened structure which I have not fixed yet. 5 years of hard racing and large lake swells has not resulted on any issues yet but it's something I'd like to fix anyway.
