Fiberglass boat issue
Will it float? Will it sink?

Not too excited about the prospects of sinking a boat in 39 degree water.
My old fiberglass tri hull barge has some cracks in the gel coat along the bottom.  See pic.  The pic is not my boat, but gives you an idea about what I am talking about.
The red mark indicates the spot where there are 3-4 cracks running.  It appears on both sides for 18-24 in.  on one side there is the appearance of whiter gel coat as if it had been redone years ago.  I have owned this boat for years, but only put it into service within the last year.  It also appears to be occurring roughly along the line of where the floor intersects with the hull.  The boat is not  worth putting much money into.  I may continue to use it for a time, but gingerly puttering about in it to not stress the hull much.  Anyone have any thoughts?

I can't tell how bad the cracks are from your photo, but they do sell some stuff to repair cracks and gouges in fiberglass hulls. I got into some hard stuff fishing under the birds in upper Oologah a few years ago, put a couple of serious scratches through the gelcoat on my rig. Bought the stuff at the basspro store, and it's held up very well.

It Is probably just the gelcoat is cracked. The fiberglass is much stronger and thicker. I would not worry about it sinking at all. I have some of that gelcoat repair, it is an epoxy and works pretty good the catalyst to resin ratio must be mixed accurately. 
 Here is a link to a video that sort of explains why it cracks

Slick, that is not my boat in the pic.  I am too embarrassed to show the real thing. LOL!
If that gel coat fixit cost more that $20 it will double the worth of my barge, but it floats and the fish like to slime up the repaired plywood floor.
I'll patch it and keep fishing.
