Brian,

Many thanks. I will try this first and only consider glass work as a
last resort. BTW, I have no complaints about this boat (which was used
when I bought it) despite this minor problem. I have paddled maybe 8 or
10 different touring boats, and this one is by far my favorite --
extremely fast, great secondary stability, tracks well, and very
comfortable.

Impex makes fine boats. Leaky hatches happen in every brand of kayak.
Unless it's a structural issue, there's not too much to complain about.
If it was a structural problem, I'd bet that Impex would make it right.
