BURLINGTON, Vt. (AP) — A Vermont ferry company is considering sinking a retired boat in Lake Champlain.

WCAX-TV reports Lake Champlain Ferries has decided to eliminate one of the three boats that travels from Burlington to Port Kent, New York. The company says the cost to disassemble the boat in order to sell it is too high.

There are already 10 buoyed vessels in the lake's underwater historic preserve.

University of Vermont Professor Ellen Marsden says artificial reefs provide a habitat for fish to forage and spawn. However, Marsden says that the ferry would have to be clean enough to pass a list of state and federal standards.

The company hasn't calculated the cost of sinking the boat yet.
