I am sorta with Joli. As long as you can bail faster than it comes in, have fun...

Seriously though - This could be a common problem on the Mac 21. You may need special advice. Here are a few sites with Macgregor focus.

I am unfamiliar with a "Mac21"but I never heard of a boat which characteristically leaks and therefore should be of no concern. Kind of counter-intuitive, isn't it?

Guess one could be of the mindset - screw it, if it sinks, the government will come to my rescue at great cost to somebody else.

I've just went through the same thing. I have a similar boat. If the wet spots are where the trailer bunks contact the hull you most likely have stress fractures. Not the that hard to fix. Sand the area down to the glass. Locate the cracks at both ends. If you just glass over them the cracks can still spread with stress over time. To fix a crack for good drill a small hole at both ends of the crack (this will stop a crack from spreading). File or grind a bevel along the crack inside/outside (this will allow the resin penetrate the crack) . Fill with resin. Let dry. Sand. Apply a coat of glass over area inside/outside.Let dry. Sand. Water test before repainting.

take some pictures, let's see this area. Try to take some good pics. good focus is primary. don't worry about getting real close to the water spot leak area, we all have software that can magnify it a million times. Get close enough that you can use the "close up" mode on your camera (dayligth without flash for a few) and get it real good. Then we can be more subjective in our armchair analysis.

Like Joli said, for Gods sake, it's a daysailor... they all leak. LoL
the perfect dive boat is one you're on...
