Had some bad luck last week and my boat was washed ashore during a big storm. The beach it ended up on is soft sand so things could have been worse.
Boat is a WA built custom 30 with an integrated keel. Now I 've noticed some thin cracks on the starboard side of the hull on what looks like maybe some kind of joint and also a hairline crack on the the keel \ hull joint on the port side.

I've no idea on how to assess repairability and am hoping for some advice from this forum. Any ideas on how I should approach this?
Have included some pics of how the boat ended up and damaged areas.

Thanks

to me if it had a hull either side of it even two of these as beaching legs it would not fall over




and they could be your work benches in a restoration project

The hull cracks seem to be far from random in their direction and position, and suggest that this is the boundary of a structural area designed to take side thrust from the keel. If so, you will need to reestablish the transition lines, which will mean tapering the cracks completely out and epoxy glassing . I would suggest that if this is needed then that you support the hull and keel with accros and only do the repair in stages so as to minnimise hull distortion. The keel crack probably needs similar treatment. That joint seems very abrupt - i.e., no attempt to champher the joint. Does the boat have keel bolts?

I dont think boat is damaged in any significant way > What I see is hull has flexed and the built up paint has cracked the fiberglass can flex a long way the paint does not Cheers PS. best of luck with it

I agree that these cracks are probably just in the gel coat. Google" fixing gel coat cracks" for repair technique.
The cracks on the starboard side look like they have been caused by some internal structures which are strong in compression, transferring the load from the port side onto those positions on the starboard side. Look at the structure inside the hull to confirm that analysis.

Digging into the gel coat will soon reveal if the main structure is cracked, or just the gel coat.

Further to all this, the port side crack looks like a tension crack and the stb side crack looks like a compression crack. It would be interesting to see of the thwart ships crack, aft, corresponds to a bulkhead, and if the longitudinal crack corresponds to some interior furniture. If so, I would be thinking hard about doing a proper repair.
