Using a step drill, create about 1/4 diameter drain hole in front of bulkhead where water collects.







Or, behind if the water is moving forward to get to the bulkhead! I have seen gliders with drain holes in the fabric always to the right of the rib. I guess this was a "left wing low" glider!







But, yes, to Hank's advice. Add a small hole where appropriate. And quarter inch sounds about right to me, too.



And FWIW, make sure that the "maintenance guy/gal" for that ship keeps them clean. A number of our club gliders have drain holes in various places that get plugged up pretty regularly. Spoiler boxes on a particular glass two place leap to mind.

Sounds like I'll need to talk to our A&P to put some carefully placed drain holes in there. Talked to Kyle at K&L when I ordered the replacement release return spring, and he said that they have no "official" method of doing this. So I guess it's a mod IAW AC43.13 then.
