that crack may be a blessing in disguise ......if you gelcoat was marginal it very well could have been a seed to a future blister problem.....is you hull cored....if so look on the inside as well.....

Agreed. Keel should not be hanging free.

It's not, the keel is blocked up. In fact the boat was set on the blocks then the stands moved into place and adjusted for support. They (the stands) also have wood support. They just don't show in the photo.

I have noticed some oil-canning from the stern stands in the past. Fortunately, no permanent damage was done. Hopefully, the cracks you show on your hull are cosmetic.

Catalina 310s are made with vinylester. So there is no blistering concern. The hull is solid glass.

On the last haul out my 2005 had some blisters.

That's really strange. I don't think a major boat builder has seen a case of blisters since the late 1990s. It's a chemical process that doesn't happen with vinyl ester. Are you sure it was blisters and not voids in the layup?

Just looking at the photos again and I noticed something. It looks like fresh bottom paint has been put on and the stands may have been moved to apply bottom paint. Did the yard move the stands?

The truth is I wouldn't know a blister if it broke open and spit at me. However, the yard guys said blisters, and the marine surveyor said blisters. They were small little lumps, perhaps 3/32 proud of the rest of the hull. There were five, small, about 1/4 inch to 1/2 inch in diameter, all within a 3 ft diameter circle on the starboard stern, behind, and toward the waterline of the raw water intake.

Did the surveyor give you any pics or other details? Do you have pics of the repair being done?

Sorry to push but if this is blisters that could mean that Catalina had a problem with their vinyl ester formula and that could be a major concern for all of us that own later model Catalinas.

Thanks,

Jesse

This is what the survey said:
Approximately 4-8 blisters sighted at the transom with sizes from 3/4" to 1 1/2 inch. These do not appear to be a serious issue but should be properly treated at next haul out. Smaller blister approximately 1/4"-1/2" in size sighted at thru-hull fittings. These should also be tended to at next haul out to mitigate any further problems.

Trying to upload the picture, but it isn't going well. The file is only a 280 mb JPEG but has not loaded after 15 minutes. If anyone want to see a picture, e-mail me.
