J.B & J.D. Van Deusen was a 19th-century American shipbuilding company started by Joseph B. Van Deusen and James D. Van Deusen in 1865. The shipyard was in Williamsburg, Brooklyn. Some of the finest yachts, schooners and steamboats in the New York were designed and built by them. The last boat that was built at the shipyard was the schooner-yacht Mohawk in 1875, which was later renamed Eagre and transferred to the United States Navy in 1903.
