There was some discussion on here recently on the technique, I think it was attached to one of the photos, can anyone point me in the right direction please?

Thanks Ron. Didn't realise quite how prolific you are!!

When we bought Blue about 4 yrs ago, the survey pointed out the roof was sagging, round the mast foot - a design fault apparently.

I am beginning to think about fixing it; getting the mast off, jacking the roof up gently, reinforcing the beam, and replacing the four s/s bolts joining the bulkhead to the existing beam with bigger ones.

Sounds simple.......

It might not be necessary to drop the mast ,although its not a major job,just slacken everything. The roof beam looks very strong to me unless the balsa core got wet. We will strengthen Goskar as a precaution but im sure the standard beam would do the job even with a lot of bulkhead removed. I think the worst part of your job will be grinding back to smooth the fiber glass on the beam ,very dusty.
Possibly use four more bolts as well asthose there and glass over the whole . Have a look at goskars photos ,Its not a difficult job really
Remember Ian works in Falmouth and goes through Ponsarden every afternoon at 4.30 pm !

I agree the beam looks strong; but there is no getting away from the fact that the roof has dropped, and the four bolts have sagged - they point downwards 5 degrees or so.

I like the idea of leaving the mast up. Would it be a worthwhile compromise do you think to leave the mast up, slackening the shrouds before gently jacking the roof up, and glass another beam to the roof, flush with the existing beam, and epoxied to it; and then replace the four bolts with bigger ones?

Or we could just leave it as no harm seems to have come to it yet.....
