We have the same issue with our Capri 22. We discovered it two years ago. From condition of the delamination, we surmised that it had been there quite a while, possibly even before we took possession. What I did was mark the length with a Sharpie, and examine before every sail. We have sailed 49 times under this condition, with no water issues and no increase in the delamination. We are lake sailors, so the hull rarely takes much pounding. My plan, however smart, is to wait for a worsening of the delam, and or keeping vigilant for water issues. (And always in a PFD.) BTW, hull #642.
