Nice looking boat. Huge genny and small main. What is the hull shape like?
Is this a new boat to you?
As an owner of a boat from 1967 (Tartan 27') I'd suggest you look at the chain plates to see if there is any possible water penetration in them. All internal sheaves and blocks in the spars should be checked as well. I suspect you know the deal with older boats but I am just saying that older stuff is more likely to fail or foul. Maintenance is key IMHO.
