Crack at back of boat
 
Ive got a crack (not stress crack) at the back of the boat.

Ill get a pic of it, but heres the best way to explain it. If your looking from the back, you have the "v" then the parts that are horizontal (im guessing stringers go there) Its on the flat part, and its at the edge of the back and the bottom. Its about 2 inches across the back, then it goes under the boat about 3 inches. Is that real bad, or something that can be fixed? It just showed up after hitting some big waves this weekend.

That doesnt sound good. It's supposed to be the strongest part of the boat. Id take a bunch of pictures and get them to Baja and see what they say.

I would say boat is too old for Baja to give a dam.

Based on the way I am picturing it, is the stringer &/or transom got water in it & rotted. From inside or outside of boat is fiberglass transom & stringers sponggy? I would call around & see if there is a good fiberglass shop in Austin. Take to them & see what they say.

That doesn't sound real good. Is there any signs of water leaking out of it, i.e., brown stains? Take a rubber mallet and thump along the transom and bottom. You will hear a dull thud if it is waterlogged, instead of a sharp rap. Also check the stringers.

Are there any thru-hull fittings, screws, etc. in the vicinity of the crack? These are prime locations for water intrusion if they are not sealed up properly. All it takes is a little bit of water to get past one and into the core, and it will wick into the core like a sponge.

See if you can get a marine surveyor to look at it. Good luck.

Take it to a good boat glass shop. Then buy some Maalox.

Sounds like your describing the lifting strakes under the boat. Since they dont like to flex they will crack if forced beyond design strength. Go in your bilge and study the mounting of your motor, the motor is suspended between the stringers and the inner transom plate on the transome.
When we launch and re enter the load on those mounting points is multiplied. Check your stringers at the point of the forward mount and the mount itself, most likely that would be the point of origin for the flex. A repair of this nature must be done inside and only a cosmetic repair outside. If you try to cosmetic patch it on the outside it will only reappear shortly after your next ride.
Usually not a lot of materials, but a fair amount of labor.
Take off drive, remove motor, grind out damage, patch, etc.:eek:
