Re: [Paddlewise] Deck/hull seam

I've never had a problem with bulging hatches on my Romany - but I always
burp all of the hatches.  My husband (who also has a Romany) does have
bulging hatches.  He doesn't usually burp his hatches.  I always thought
that was the one variable, but now I'm hearing that the hatches may bulge
even if they are burped!
