I think a properly made repair like this (actually, an insert) would be as strong or stronger than the original. The only downsides are esthetics and a bit more weight aloft.
Selden extrusions are often shipped in sections which are then joined with an insert.
If you're concerned you should get a rigger to take a look at it.

How much has the boat been used in the last 15 yrs. After being flipped I imagine it was in for a long period of rehab.
I think it has been used pretty normal. It is an Edelcat 33 and it has no real saloon. I would more call it a protected cockpit. It has 10 years old sails, 4 years old outboard, hard dinghy, but not much more. No water tanks/system or big fuel tank, small battery bank, no instruments, no windlass etc. I think it needs equipment for about at least 10-13k.
The question is...if I would go for this or a bigger trimaran like Norman Cross 39/40
I agree with ziggy. Might be stronger but just a bit heavier and since it is supported by spreaders there is no danger of breakage again.
kind regards,
That looks nasty. Are those welds? Sleeves in a mast are fine. Even new ones have them. It will never break in that spot again. However, as above, I'd have a rigger or spar builder take a look at it.
