Hi, this probably does not help much but anyway; we had a World 10 years ago and replaced the bailers when they started leaking.
I did not expect the old ones to come out intact, but actually they were in quite good condition. The filler between the inner/outer hulls around the bailer aperture was pretty poor. That was the main cause of the problem. I hacked it all out and made good with epoxy filler. Then replaced with new bailers.
