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.
