After 20 years of trying to locate and eliminate leaks, we put a blower on top of the forward
hatch and pressurized the boat...plugged up the major
exhaust points like dorades, etc. Then from the outside, with a mop, we put soapy water all around the deck. The leaks were obvious...mostly in the cap rail which we grouted out an re-bed. But we also found leaks in the windows, etc. This is by far the best way to find leaks and not that hard to do.
