We have a persistent and hard to trace leak from the cockpit of our Hunter 38 into the aft cabin. Before removing all the interior trim to try to trace the leak, I'm wondering if anyone has had any experience of using a flexible inspection camera or boroscope to view spaces between their deck and hull liners? What works and what doesn't? I tried a cheap inspection camera from our local electronics store but the image quality was way too poor to be of any use in detecting a small leak.
