Breathers / Drain holes

   Many of my previous grp boats had breathers in the hatch cover so I think, as a start, I would drill a very small hole in the centre of your existing hatch cover.  Then think about reinstating the drain holes for the reasons Jim has mentioned, depending I suppose on why they have been filled in.  Might be worth asking that question.

	I can't imagine the pressure doing any good at all. I'd definitely put a breather in. How odd to fill in the drains. Wooden self draining boats are enough of a rot trap as it is.

	I've just bought back Sacré Blue the Farr 3.7 I imported to start the class a few years ago, and the boat has had the drain holes in the stern filled in. But has been made water / air tight. i.e undo hatches and get a rush of air. Question - is this going to make the boat over pressurises and do something bad? Does it need a breather pipe. Farr 3.7's are built quite light - 4mm ply hull skin. The only boat I've had that was like this was a Moth and it had a breather. But then again I think it also had drain plugs?
