hull cracks??

[weekender1]

Hello again well have been doing some good work on the boat foam in all new stringers and floor.
but what i have a question about is there are cracks on the bottom of the hull she is a try-hull i was woundering if they would be caused do to the fact that the old stringers where gone as in wood pulp and when the boat was in the water and going over waves would flex since the stringers where gone would that cause the cracks and also i was told to use and interlux type of bottom paint that would go into the cracks and then seal them? and how do you paint or do the bottom of the boat if you are unable to get her off the trailer as in no place to put her?

It is somewhat hard to tell, but it looks like the cracks came from sitting on the trailer while having rotten stringers. You should repair with gel coat rather than bottom paint.

When you put any type of paint over cracks it just bridges over them and typically cracks again, sometimes even before you can get it back in the water. Some epoxies claim to be able to hold up when painted over cracks, but I've never seen it work long term.
