USS Apache (SP-729) was the first to be delivered of eight motor boats built by Herreshoff Manufacturing Company at Bristol, Rhode Island ordered and financed by members of the Eastern Yacht Club of Marblehead, Massachusetts.

Apache, as were the other boats, bore names under construction chosen by the owners and were then given the Section Patrol numbers on Navy acceptance and activation.

The launch was found unfit for service and turned over to the United States Shipping Board for disposal 18 March 1925.

Apache was among eight motor boats that were financed by members of the Eastern Yacht Club of Marblehead, Massachusetts to be built by the Herreshoff Manufacturing Company at Bristol, Rhode Island, to a design by Albert Loring Swasey and Nathanael Greene Herreshoff that had been approved by the Navy with the intention the boats be used as patrol craft in event of war.

A unique design feature was a dummy stack, unnecessary on a gasoline powered boat, that was actually an access to the engine compartment.

However, this proposed movement appears to have been cancelled, probably because of the armistice with Germany of 11 November 1918 that ended World War I and eliminated the need for more U.S. Navy patrol craft in Europe.

AB-2 later was found unfit for further Coast Guard service and was transferred to the United States Shipping Board on 18 March 1925 for disposal.
