carmarthen bay

has anyone on ribnet had any problems with a ribcraft fitted a frame on a 5.3 ?

i noticed alot of flex (forward/backward movement) from the fixing brackets and on closer inspection i thnk there is a small fracture appearing on the weld that attaches transom fixing bracket to s/s frame.

i think it needs rienforcing some how? any suggestions?

This doesn't surprise me.
I was looking at a newish Ribcraft 5.3 with a nice shiny A-frame the other day and I noticed the forward legs of the A-frame aren't fixed to the deck, but bent rearwards and welded onto the rear tube sections at the transom mounting plates. The set-up lacks the rigidity of an A-frame with forward legs fixed to the deck.
Any decent fabricator should be able to weld some webs between the tube/flat plate which will reinforce the attachment point. It would be better to fix them down to the deck somehow, although this would be a bigger job.

Nice boat, BTW - looked like you were having a rite larf out there.

Any movement in s/s welds will result in failure.

Wobble, wobble, work harden, crack is the technical explanation I think.
