There's no real premium on low production boats...indeed, they usually are worth less than the equivalent of a more popular boat.
Unlike some things, where rarity is a plus, it rarely is with boats.
Your boat's value will depend entirely on condition. It's just an old boat in the marketplace, I'm afraid.
I'm betting it's a fiberglass trihull design.
What outboard is on it? If that's in good shape, it's probably the most valuable thing about your setup.
