By now, evidence of mast compression
- if any - should be quite evident. Chain plates are life-limited items and the material of which they are made is usually independent of the price
of the boat. Instead, look at how easy it will be for you to remove them for inspection/replacement...as for that age of boat, that will likely end up on your To Do list. (Glassed in? Access to fasteners sufficient to work a ratchet while holding a bolt head
?) Hull/deck joint will be difficult to fully examine, I suspect, due to the liner - and the inevitable dark/tight spaces into which we try to force our bodies. So where this is difficult, look for signs of water
damage and mold
. Sometimes, even the 'smell' will tell you what you can't see.
I would think a 'good' version of this boat is very suitable for your purposes.
