looking at a old tolly its a 1969 28' express- i think. by appearance this boat is very nice for the age, ive given it a once over and i plan on going back for further inspection- what should i look for? the hull seems to be in very good condition, the deck is equaly as nice, the upholstery and intierior are decent but not great, ive only knuckle tapped the stringers and the transom, and this is what im most concerned about- do tollys have a weak point to look for? thanks- Russ
