There are several boatyards and marinas in Deltaville, and a machine shop is situated on the creek. Berths, gasoline, diesel fuel, water, ice, a sewage pump-out station, and marine supplies are available. Hull and engine repairs can be made.

Broad Creek, which forms the primary harbor for Deltaville, is used by oystermen, fishing boats, and yachts. A dredged entrance channel, marked by a light, buoys, and daybeacons, leads from the Rappahannock River to natural depths of 7 to 5 feet inside the creek. In 2011, the midchannel controlling depth in the creek was 8.5 feet.
