If you want to move into high performance single seaters, your
options will be somewhat restricted, but you'll manage to find
something. Its typical for Euro gliders to come out of the factory
with a max cockpit load of 242 lbs (110 kg.), but that often gets
reduced when extra equipment is installed.

Most high performance gliders have provision to store ballast in the tail.
This could increase the minimum cockpit weight. You will have to reduce the
water ballast accordingly to stay below gross weight.

I will assume you meant "maximum" cockpit weight.

Isn't water ballast a different issue from fuselage weight? In other
words, it may be perfectly ok, structurally, to add 300 lbs of water
in the wings but that same 300 lbs added to the fuselage (with pilot)
would not be ok. The issue is the structural limits of attachment of
the fuse to the wings, I believe. Perhaps I simply misread your
message and this is not what you were implying. But I add this
comment just to make the issue clear to the original poster.

Water in the wings does not stress the attachment of the fuse.
