My boat takes on water in the starboard hull. Its not a lot usually I can get it out with 3 or more sponge squeezes after a day out. My concern is if its at the base of the daggerboard well one day it could get bigger fast so I want to figure out where the entry point is and try and stop it without resorting to gobbing on silicone seal everywhere. The top of the hull cross brace attachment was suggested but they spend zero time underwater. Has anyone pressure tested their hull or devised a positive/negative pressure test? Just under the upper rudder pivot there is a weep hole I could use for a test port. Another boat like mine has the same problem he hasn't found the spot yet.
