The quality, strength, and longevity of Tollycraft boats are legendary. Most Tollycrafts from the 60's and 70's are still going strong. This boat is no exception. The hull is solid fiberglass with no coring used below the rubrail. Even the stringers, the backbone of any boat, has no wood to rot. These stringers are beefy fiberglass formed over a foam that is non structural. Stringer rot is a death sentence for boats, and the cost of repair is usually not worth it. This Tollycraft will still be going strong even after most boats have seen sent to the junkyard.
