Asa Shiverick launched his first vessel, a schooner, in 1815. This was followed by a square-rigged brig, many more schooners, and eventually eight handsome clipper ships that would grace harbors around the world. The Shivericks (Asa would be joined by three sons in 1837) moved the shipyard near the mouth of Sesuit Creek to enable the launch-ing of the much larger clipper ships, the only Cape shipyard to build such vessels.
A plaque honoring the Shivericks was dedicated in 1924. It is located on the west side of the harbor, on the right side of the road, over looking the parking lot.
