A public boat landing and a boatyard are in Hither Creek. Gasoline, berths, a 10-ton mobile hoist, a pump-out station, storage facilities, ice, provisions, water, and marine supplies are available at the boatyard; hull and engine repairs can be made.
Inside Eel Point lie Madaket Harbor and Hither Creek, immediately to the southward. Madaket Harbor is shoal with depths of 2 to 10 feet. The northerly approach to the harbor and creek is marked by a seasonal lighted bell buoy. The channel that leads southward from over the bar in Nantucket Sound is marked by private seasonal buoys, floats, and markers. With local knowledge, a depth of about 3½ feet can be carried over the bar and channel to Hither Creek. Local knowledge is also required to enter the harbor from the southwest.
