and difficult. The depths are less than 2 feet (0.6 m) at low water and there is a shoal outside the jetties.

The Harwich exchange building at South Harwich, a square building with cupola, shows up well from seaward.

Witchmere Harbor, 334 miles westward of Stage Harbor Lighthouse, has an entrance 100 feet wide between two jetties. There was a depth of 5 feet (1.5 m) in the entrance channel in a width of about 60 feet and 6 feet (1.8 m) in the pond and at the landings in 1932. The channel is subject to shoaling. Harwich Port is a village on the pond and a yacht club is located there. Gasoline and a small quantity of provisions can be had. A church spire a little west of the entrance is prominent.

Allens Harbor, 1 mile westward of Witchmere Harbor, has an entrance between two jetties. In 1932 there was 3 feet (0.9 m) over the bar, and 5 feet (1.5 m) inside. The channel is winding, but leads between solid marsh on both sides and is not difficult to follow. The harbor affords good anchorage for small craft.

Herring River, 6 miles westward of Stage Harbor Lighthouse, has an entrance between two short jetties and is frequented by yachtsmen and fishermen. A channel 60 feet wide and 6 feet (1.8 m) deep has been dredged through the bar at the entrance, but has shoaled to about 4 feet (1.2 m) in 1932. A basin dredged southerly of the Lower County Bridge affords anchorage for vessels drawing up to 6 feet (1.8 m). Dennis Port is a village just inside the entrance. A white hotel on the west side of the entrance is prominent.

Bass River has an entrance between two jetties. A channel 60 feet wide and 6 feet (1.8 m) deep has been dredged to the entrance and between the jetties to an anchorage basin of the same depth just inside. The channel is marked by private buoys, locally maintained from April 1 to January 1, and is subject to shoaling. In 1932 the controlling depth was 5 feet (1.5 m). The end of the west jetty is marked by a flashing white light and there is a prominent spoil bank on the inshore end of the east jetty. The villages of South Yarmouth and West Dennis are on the river 114 miles above the entrance. Gasoline and provisions can be obtained here.

On the easterly end of Dogfish Bar, southeastward of Bass River entrance, there is a small breakwater which was formerly used as a shelter for small craft. The area around it and to the northward has shoaled up and the breakwater is no longer used.

Bishop and Clerks is an extensive shoal lying southward of Point Gammon and marked near the center by a lighthouse. There are several rocks awash at low water on an arm of the shoal extending nearly 8 mile southward from the lighthouse, marked at its end by a red buoy. The remainder of the shoal has depths of 12 to 18 feet (3.7 to 5.5 m).

Bishop and Clerks Lighthouse is a gray granite tower. The light is flashing white; flash 2 seconds, eclipse 8 seconds, 56 feet (17.1 m) high and visible for 12 miles.

Point Gammon, at the eastern entrance to Hyannis Harbor, is a prominent wooded point marked by an unused lighthouse tower. A reef, partly bare at low water, extends 1/2 mile southward from the point, and is marked at the end by a red buoy. Extensive flats, with rocks bare at low water, extend 1 mile northwestward from

Point Gammon. Great Rock, a bare rock marked by a spindle and cage, is on the western edge of the flats. A red buoy lies 300 yards westward of Great Rock.

Hyannis Harbor (chart 247). This harbor is used considerably as a harbor of refuge by coasting vessels of less than 14-foot (4.3 m) draft, which anchor behind the breakwater, where an area nearly 3 mile in diameter has been dredged to a depth of 152 feet (4.8 m). The depth in the channel up to the breakwater is 15 to 16 feet (4.6 to 4.9 m), but the approach is somewhat obstructed by the flats extending westward from Point Gammon and an extensive shoal with numerous rocks on the west side of the channel. Ice seldom interferes with the movements of vessels, the prevailing northerly winds keeping the harbor clear. Bishop and Clerks Lighthouse, the buoys and the light on the end of the breakwater, are the guides for entering, Pilots for the harbor are located at Vineyard Haven, or local fishermen will come out on signal.

Hyannisport is a village on the northerly side of Hyannis Harbor. The railroad wharf is out of repair and is no longer used. There is a dredged basin 6 feet (1.8 m) deep leading to the south side of the yacht landing on the west side of the harbor. Gasoline, fresh water, and some provisions can be obtained here.

Lewis Bay, large and shallow, extends northeastward from Hyannis Harbor. A channel 9 feet (2.7 m) deep has been dredged through the bar at the entrance and is marked by buoys. This channel is subject to shoaling. The channel leading from Lewis Bay to Hyannis has also been dredged to 9 feet (2.7 m). The deepest draft taken to Hyannis is about 8 feet (2.4 m) at high water. Lewis Bay is closed by ice for about two months each winter.

In 1932 additional dredging was being done at Hyannis. The project provided for building a bulkhead and town landing to afford berthing of vessels drawing up to 9 feet (2.7 m).

Hyannis has railroad communication and is quite an important summer resort. Gasoline, ice, provisions, and some yacht supplies can be obtained here.

Directions, Hyannis Harbor-From eastward.-Pass about 34 mile northeastward of Bishop and Clerks Lighthouse and 200 yards southward of Hallets Rock buoy (horizontally striped), then bring Bishop and Clerks Lighthouse astern on a 318° true (NNW. 3% W. mag.) course until the breakwater light bears 8° true (NNE. mag.). Then steer 11° true (NNE. % E. mag.), passing 60 or more yards eastward of the end of the breakwater, and anchor about 300 yards northeastward of the eastern end of the breakwater in 15 to 20 feet (4.6 to 6.1 m), soft bottom. Small craft can anchor farther northward toward the railroad wharf in 6 to 12 feet (1.8 to 3.7 m), but should stay clear of the wharf, as there are some old piling under

water.

From westward.-Pass close southward of Wreck Shoal spar buoy No. 18 and steer 74° true (E. % N. mag.) for 214 miles, heading for Bishop and Clerks Lighthouse, and pass southward of Wreck Shoal buoy (at eastern end of shoal) and well northward of the buoys marking Eldridge Shoal and the northwest end of Horseshoe Shoal. Then steer 59° true (ENE. 5% E. mag.) for 42 miles to a position about 3 mile southeastward of a red lighted be!l buoy.

161875°--33--5

When the breakwater light bears 10° true (NNE. 14 E. mag.), steer 11° true (NNE. % E. mag.), passing eastward of a black buoy, and proceed as in the preceding paragraph.

Vessels going to Lewis Bay or Hyannis must be guided by the buoys marking the dredged channel and by the color of the water, deepest where it is darkest.

HYANNIS HARBOR TO WOODS HOLE (CHART 1209)

Centerville Harbor (chart 247) is a bight 2 miles wide in the north shore of Nantucket Sound, westward of Hyannis Harbor. The approach to the anchorage is obstructed by rocks and shoals, through which a buoyed channel, with a depth of 10 feet (3 m) at low water, leads to the anchorage, which has a depth of 15 to 21 feet (4.6 to 6.4 m) and good holding ground. Vessels seldom anchor here for shelter, as the harbor is exposed to southerly winds; the shoals off the entrance somewhat break the force of the seas from southward, but not sufficiently to make it a safe anchorage. The deepest draft entering is about 12 feet (3.7 m). Ice closes the harbor in winter.

The shoals in and off the entrance of Centerville Harbor, which are bare at low water, are Collier Ledge and Southwest Rock (both marked by beacons), Gannet Rocks (unmarked), Spindle Rock (near the head of the harbor and marked by a red buoy), and numerous rocks southward of Hyannis Point. There are numerous unmarked rocks with 1 to 6 feet (0.3 to 1. 8 m) over them.

Centerville is a village inland from the head of the harbor; a church spire in the village is prominent and is used as a guide for entering the harbor.

East Bay, on the west side of Centerville Harbor, has depths of 2 to 4 feet (0.6 to 1.2 m). Its entrance is 250 feet wide between jetties, through which a channel has been dredged 60 feet wide and 6 feet (1.8 m) deep, but it is subject to shoaling. With local knowledge a draft of 3 feet (0.9 m) could be carried to the landing on the southwest side of the bay in 1932. Two private buoys mark the entrance to the channel in summer. This bay is used principally by oyster boats, but local launches often pass through the bay into Centerville River. The river has been dredged to a depth of 5 feet (1.5 m) practically to the head of navigation. The width of the channel is 40 feet. A drawbridge, open at all times, except when in use, crosses the river near its mouth. Small boats anchor in the river off the village of Centerville, or tie up to private piers.

Directions, Centerville Harbor.-A 330° true (N. by W. 14 W. mag.) course, passing eastward of Gallatin Rock buoy, midway between Bearse and Channel Rock buoys, and westward of Gannet Ledge buoy, leads over a least found depth of 10 feet (3 m). Anchor about 2 mile from shore in 15 to 21 feet (4.6 to 6.4 m) soft bottom. Strangers should not enter except in the day time with clear weather.

Cotuit Anchorage is an anchorage for small craft between the shoals making off from the shore about 62 miles westward of Point Gammon. It is exposed to southerly winds and is seldom used except by local craft. The channel is marked by buoys, and vessels

EAST AND WEST BAYS

of less than 6 feet (1.8 m) draft should experience no difficulty in keeping in the best water. Anchorage can be had close northward of buoy No. 4, in a depth of 10 feet (3 m); or from buoy No. 4, steer 346° true (N. 1% E. mag.) and anchor in 7 to 12 feet (2.1 to 3.7 m) 12 to 1/4 mile from shore. Approaching from westward the channel between Succonesset Shoal and Wreck Shoal is frequently used.

West Bay, on the northerly side of Cotuit Anchorage, has an entrance 200 feet wide between jetties, and a depth of about 4 feet (1.2 m) at low water can be taken through the entrance and the narrow channel leading to the northern half of the bay. A flashing white light is maintained, from May 15 to October 15, on the east side of the entrance cut. The channel is usually marked by private buoys during the summer. There are numerous oyster stakes in the bay. A depth of about 4 feet (1.2 m) can be taken through a narrow channel from West Bay to Great Bay. It is crossed by a drawbridge with an opening about 14 feet wide. There are several oyster wharves in the vicinity of the bridge. Ice closes the bay for about two months each winter.

Cotuit Bay, northwestward of Cotuit Anchorage, is entered through a dredged channel 100 feet wide and 6 feet (1.8 m) deep, and there is a greater depth in the bay except at its southern end. The channel is usually marked by bush stakes. A depth of about 6 feet (1.8 m) can be taken through the narrows from Cotuit Bay to Great Bay; the latter has depths of 6 to 18 feet (1.8 to 5.5 m). Local knowledge is necessary for the navigation of these bays. The bays are closed by ice about two months of each winter.

A channel 6 feet (1.8 m) deep has been dredged in the Seapuit River, affording a connection between Cotuit and West Bays.

Cotuit is a village on the western side of Great Bay, and Osterville is a village on the eastern side of Great Bay. Gasoline, fresh water, and provisions can be obtained at these villages. There is a depth of 4 feet (1.2 m) at the wharves at Osterville. There are facilities for repairing small boats at Osterville and Cotuit. The nearest marine railway is located at Falmouth.

Poponesset Bay is used only by local oyster boats. The entrance is narrow and unmarked, dredged to 60 feet wide and 6 feet (1.8 m) deep, and extends southwestward from the inner end of the entrance channel of Cotuit Bay. The entrance channel is subject to shoaling, and in 1932 was good for the draft of only 3 feet (0.9 m). The greater part of the pond has depths of 2 to 4 feet (0.6 to 1.2 m).

Waquoit Bay has general depths of 2 to 8 feet (0.6 to 2.4 m) and an entrance about 250 feet wide. There is a jetty on the southeast side of the entrance. In 1931 a channel 60 feet wide and 6 feet (1.8 m) deep was dredged from the sound into the bay. There was about 5 feet (1.5 m) on the entrance bar at low water in September, 1932, and about 5 feet (1.5 m) in the channel to the anchorage.

Menauhant is a summer colony 1 mile westward of the entrance to Waquoit Bay.

Between Waquoit Bay and Falmouth Inner Harbor are several ponds whose outlets are closed and not used. There are several jetties along the beach to protect the shore.

Falmouth Heights is a prominent yellow bluff on the summit of which are numerous houses and a large hotel; it lies just eastward of the village of Falmouth and about 3 miles east-northeastward of Nokska Point Lighthouse (chart 249).

Falmouth Inner Harbor, westward of Falmouth Heights, is entered by a dredged channel 100 feet wide and 8 feet (2.4 m) deep between jetties; the outer end of the west jetty is marked by a flashing green light. An anchorage basin 1,300 feet long, 100 to 350 feet wide, and 8 feet (2.4 m) deep has been dredged inside the entrance. The greater part of the pond has depths of about 6 feet (1.8 m). There are several small marine railways. The largest can handle a boat 70 feet long, draft 8 feet, and up to 30 tons. Gas engine and hull repairs can be made. The depths at the wharves are from 7 to 8 feet (2.1 to 2.4 m). Gasoline and provisions can be obtained.

Falmouth Harbor is the open roadstead on the north shore of the sound from 1 to 3 miles eastward of Nobska Point Lighthouse. It is frequently used by vessels with good ground tackle, who prefer the anchorage here to the one in Vineyard Haven on account of the crowded condition of the latter in bad weather. It affords a lee in northerly winds, and in southerly winds the sea is somewhat broken by L'Hommedieu Shoal, so that vessels with good ground tackle can ride out a gale in comparative safety.

The anchorage in Falmouth Harbor is about 3/4 mile from shore in 4 to 6 fathoms (7 to 11 m), and small vessels can anchor closer to shore in 15 to 18 feet (4.6 to 5.5 m); the bottom is generally sticky and good holding ground, shoaling gradually toward the shore. At night, if less than 2 miles eastward of Nobska Point, with West Chop Light bearing eastward of 167° true (S. 14 W. mag.), vessels should anchor just before Nobska Point Light comes in range with Tarpaulin Cove Light; if farther eastward, vessels should keep well southward of this range. Vessels can enter from southward on a 344° true (N. 1 W. mag.) course, with West Chop Light astern, and pass about 1/4 mile westward of black buoy No. 19. Or, pass % to 12 mile eastward of Nobska Point Light on a north-northeasterly course, and when Tarpaulin Cove Light is nearly in range with Nobska Point Light, stand eastward to an anchorage.

WOODS HOLE (CHART 348)

is a narrow passage leading between numerous ledges and shoals from Vineyard Sound to Buzzards Bay, between the mainland and Nonamesset Island. It is well marked by buoys and beacons, but the tidal currents are so strong that the passage is dangerous without some local knowledge. The buoys in the narrowest part of the channel are frequently towed under by the currents. A stranger should not attempt to pass through except near slack water. Woods Hole is little used as an anchorage on account of the strong tidal currents and the narrow channel. Great and Little Harbors are on the northern side.

The northerly channel in Woods Hole from Great Harbor to Buzzards Bay has a narrow but straight reach and was dredged 300 feet wide and 13 feet (4 m) deep, but there are numerous spots with 10
