Tides.-The mean range of the tides is about 612 feet.

Currents. In the channel just south of the jetties, slack water occurs about 14 hour after the time the current turns eastward and westward at the Race (about 22 hours after high and low water at New London). The strength of flood and ebb occurs about 1/4 hour after the corresponding strength at the Race (about 1/4 hour and 14 hours before high and low water, respectively, at New London), and has an average velocity of about 214 knots. The flood sets 150° true (S. by E. 5% E. mag.) and the ebb in the opposite direction. Vessels at anchor in the harbor swing with the wind.

DIRECTIONS, PORT JEFFERSON HARBOR

From New Haven.-From the main entrance of New Haven Harbor between Southwest Ledge Lighthouse and Luddington Rock Breakwater, a 209° true (SW. % S. mag.) course for 17 miles will lead to a position off the entrance of Port Jefferson Harbor westward of Mount Misery Shoal.

From Bridgeport. From buoy No. 4, at the entrance of Bridgeport Harbor, a 159° true (S. 34 E. mag.) course for 11 miles will lead to the bell buoy at the entrance of Port Jefferson Harbor.

Or, a 176° true (S. 34 W. mag.) course with Stratford Shoal (Middle Ground) Lighthouse astern will lead for the entrance of Port Jefferson Harbor.

The tidal current in the Sound should be considered in shaping the course across it. (See "Currents, Long Island Sound" on p. 120.)

Approaching from westward, give Old Field Point Lighthouse a berth of 12 mile and steer for the bell buoy on course 109° true (S. E. by E. 14 E. mag.) to avoid the rocky shoal with 17 feet (5.2 m) over it, which is about 3% mile to the northeastward of Old Field Point Lighthouse.

Mount Misery Shoal, the principal danger in the approach to Port Jefferson, will be avoided by keeping Old Field Point Lighthouse bearing southward of 248° true (W. % S. mag.) The range of the light on the east jetty and the light on the west side of the entrance inside the jetties, bearing 176° true (S. 34 W. mag.), leads clear westward of Mount Misery Shoal.

Pass about 300 yards westward of the perpendicularly striped bell buoy at the entrance of Port Jefferson Harbor, and steer 152° true (S. by E. % E. mag.). Keeping the flashing green buoy inside the harbor halfway between the two entrance lights, pass through the narrow entrance between the jetties into the harbor. Pass 100 feet to westward of flashing green buoy and can buoy No. 1 (which are together) and steer 136° true (SSE. % E. mag.) up middle of harbor. Good anchorage in from 10 to 12 feet (3 to 3.7 m) can be had for a distance of 1/2 mile from the head. The flashing green buoy inside the entrance can not be seen over the breakwater at low tide by small vessels approaching this harbor.

OLD FIELD POINT TO EATON NECK (CHART 1213)

Old Field Point is a low bluff, on the summit of which is the lighthouse. Bowlders extend a short distance off the point and the lighthouse should be given a berth of about 1/4 mile, even by small craft. There is a gong buoy 1/4 mile northward of the point.

Old Field Point Lighthouse is a white tower on a gray dwelling. The light is fixed white, 76 feet (23.2 m) high and visible 14 miles. Crane Neck Point, 2 miles westward of Old Field Point, is a bare bluff about 90 feet (27 m) high, and is covered on top with brush. Trees extend a little ways back from the bluff.

Smithtown Bay is a broad, open bight on the south side of the Sound and extends about 7 miles westward from Crane Neck Point. Rocky shoals extend 1 mile in places from the shore, the water shoaling abruptly from 7 fathoms (13 m) in places. A good summer anchorage in 5 to 8 fathoms (9 to 15 m), sheltered from easterly winds, is found about 1 mile southward of Crane Neck Point.

Stony Brook Harbor is a shallow bay in the southeastern part of Smithtown Bay. The channel is over a bar which extends 3/4 mile off the entrance; it has a least depth of about 2 feet (0.6 m) just outside the entrance, and 1 foot (0.3 m) just inside the entrance northeastward of the first islet. On the east side of the harbor, 11⁄2 mile inside the entrance, there is a bulkhead wharf at the village of Stony Brook. The railroad station is about 1 mile from the wharf. Only small craft enter the harbor; the greatest draft is about 7 feet (2.1 m) at high water, and there is about this depth at the wharf. The estimated velocity of the tidal currents is about 5 knots in the narrowest part of the entrance.

At times there is a barrel buoy at the entrance to the channel at the outer edge of the bar, the depths shoaling abruptly from 8 fathoms (14.6 m) at this point. The range of a prominent white spire in Stony Brook and a green house with white trimmings on the spit on the east side of the entrance leads to the buoy. From the buoy the channel trends east-southeastward for 11⁄2 mile, and then curves gradually southward to the west side of the spit on the east side of the entrance. The channel then leads in mid-channel northeastward of the first islet, passes close to the east side of the northeast end of the islet, and then follows the east bank to the wharf.

There is a high bluff between Stony Brook Harbor and Nissequogue River, another between the latter and Sunken Meadow Creek, and bluffs in places between the latter and Northport Bay.

Nissequogue River is a shallow, crooked stream, the mouth of which is about 4 miles westward of Stony Brook. There are rocks and shoals, bare at low water, on the bar outside the entrance, through which there is a narrow channel, sometimes marked by stakes, with a depth of about 1 foot (0.3 m) at low water. About 1/2 mile southwestward of the mouth of the river is a State hospital, a prominent group of buildings with green roofs and a large red-brick chimney; there is a red standpipe farther westward. The railroad station is Kings Park.

There is a prominent tower about 5% mile inland and 2 miles eastward of Northport Bay.

About 234 miles southeastward of Eaton Point Lighthouse, a sand and gravel company has dredges working into the high bank and a small bight has been formed. At the east side of the entrance to the bight there is a stone jetty about 350 yards long and there is a privately maintained flashing green light on a pile at the end of the jetty. The channel into the bight is marked by stakes.

Eaton Neck is a prominent, wooded head, with elevations of 100 feet (30 m) or more, and marked at its north end by the lighthouse. The northwest end of the neck is a low spit. On the west side of the spit, 1/2 mile southwestward of the lighthouse, there are two small jetties between which is the entrance to a pond which has been dredged inside the spit by a sand and gravel company. Both jetties are partly ruined, only a few broken piling of the outer jetty showing above half tide. Great care should be taken in entering, as the channel between the jetties is very narrow. There is a depth of about 8 feet (2.4 m) through the entrance, favoring the south jetty.

Eaton Neck Lighthouse is a white, stone tower with attached dwelling at the north end of the high land of Eaton Neck. The light is fixed white, 144 feet (44 m) high and visible 18 miles. The fog signal is an air siren, blast 5 seconds, silent 40 seconds.

A general shoal area, consisting of three sections separated by channels, extends northward from Eaton Neck for a distance of 25% miles. For a distance of 1/4 mile from shore the area is foul with bowlders and of little depth. Beyond this area the bottom is broken by a series of rocky ridges, extending in a northerly direction with a least depth of 7 feet (2.1 m) 1,400 yards N. by E. from the lighthouse. The general depth over these ridges ranges from 10 feet (3 m) to 15 feet (4.6 m), and their northerly limit is marked by a black can buoy which lies 1 mile northward of the lighthouse. A rocky patch with 16 to 24 feet (4.9 to 7.3 m) over it lies 12 to 134 miles north-northwestward of the lighthouse; the 16-foot (4.9 m) spot is marked by a horizontally striped buoy. The outer part of the general shoal is a rocky ridge, approximately 1 mile in length, and is marked at its northern end by a lighted bell buoy, 25% miles N. 2 E. of Eaton Neck Lighthouse. This ridge has a least depth of 16 feet (4.9 m) 300 yards south of the buoy.

The best channel across the shoal is about midway between the black buoy and the horizontally striped buoy, where the least depth indicated by the survey is 28 feet (8.5 m); but it is not advisable for vessels of a greater draft than about 18 feet (5.5 m) to use it. Otherwise, vessels of a greater draft than about 15 feet (4.6 m) should pass in mid-sound northward of the entire shoal, between it and the 414-fathom (7.6 m) patch lying 2 miles southward of Sheffield Island.

HUNTINGTON BAY (CHART 224)

This bay, on the south shore of Long Island Sound just westward of Eaton Neck, is an excellent anchorage for large vessels, protected against all but northerly winds. The bay is about 22 miles long in a southerly direction and 1 mile wide abreast West Beach. The depths in the bay range from 434 to 6 fathoms (8.5 to 11 m) until 11/2 miles from its southern end, and anchorage can be selected according to draft and direction of wind. An obstruction, with 23 feet (7 m) over it, is about 3/4 mile southwestward of Eaton Point Lighthouse. Farther in there are depths of 20 feet (6 m) or less in places as shown on the chart, the 18-foot (5.5 m) curve extending 1/4 mile from the east shore, 3% mile from the west shore, and 3/4 mile from the south shore. Anchorage with shelter from northwesterly winds can be had for small vessels at the south

westerly end of Huntington Bay 14 to 3% mile northeastward of Lloyd Harbor Lighthouse and the same distance eastward of the unused light tower on East Beach, in 3 to 6 fathoms (5.5 to 11 m). The arms of the bay are secure harbors, Northport Bay being generally used by vessels.

Lloyd Harbor extends westward from Huntington Bay nearly to Oyster Bay, from which it is separated by a narrow strip of beach at high water. Vessels of less than 7-foot (2.1 m) draft can anchor just inside the entrance, where the depths are 7 to 11 feet (2.1 to 3.4 m). The narrow part of the harbor extending westward has a narrow, crooked channel, with a least depth of about 3 feet (0.9 m) to a point about 1/2 mile from its head. East Beach, extending halfway across the entrance, is marked near its south end by an unused lighthouse tower. The eastern shore of East Beach should be given a berth of 34 mile until the unused lighthouse bears 271° true (WNW. % W. mag.), and then enter on a 256° true (W. 1 S. mag.) course, passing 300 yards southward of the unused lighthouse.

Lloyd Harbor Lighthouse is on the outer part of a bowlder reef lying between the entrance of Lloyd Harbor and the channel leading into Huntington Harbor. The lighthouse is a square tower attached to a dwelling on a pier.

Huntington Harbor, at the southwest end of Huntington Bay, has been improved by dredging a channel 100 feet wide and 8 feet (2.4 m) deep through the entrance and through the harbor to a turning basin of the same depth and 200 feet wide at the Old Town Dock. This channel is subject to shoaling on the bar at the entrance, and in 1931 there was a controlling depth of 8 feet (2.4 m) over this bar and for 134 miles from the entrance, thence 7 feet (2.1 m) to within 200 feet of the head of the improvement. From there on the depths shoal rapidly. The entrance is difficult on account of the narrow channel, the bowlder reef which forms its western side and extends out to Lloyd Harbor Lighthouse, and the strong tidal currents which have an estimated velocity of 3 knots or more at strength. In the absence of local knowledge, only small craft should attempt the entrance and should proceed with caution.

Directions. Passing about 150 feet westward of the black buoy off the entrance, and 500 feet southeastward of Lloyd Harbor Lighthouse, steer to pass about 160 feet eastward of nun buoys Nos. 2 and 4. Pass about 150 feet northwestward and in mid-channel westward of Sandy Point, on the east side of the entrance, taking care to avoid the sandy shoal making off the point. A light is maintained on the southwestern side of Sandy Point. Follow the western shore at a distance of 150 feet, passing west of buoy No. 3, and heading slightly westward of a large yellow residence on the south shore. Beyond buoy No. 3 there are three more buoys marking the channel, the first on the north side and the others on the south side of the channel.

Huntington is a village at the head of the harbor. There is a depth of 9 feet (2.7 m) at the light plant wharf and 6 feet (1.8 m) at the oil company's wharf. About 400 yards northward of the light plant wharf is the entrance of a narrow channel, with a depth of about 3 feet (0.9 m), which leads to the coal and lumber wharves on the west side of the harbor. The north end of the wharf is shoal.

Coal, water, gasoline, and launch supplies can be obtained. There is a marine railway 65 feet long, which can take out boats of 5-foot (1.5 m) draft. There is a bus line to the railroad station, about 3 miles distant. There are several mooring buoys along the west side of the channel to which small boats tie up.

West Beach, which extends more than halfway across the entrance of Northport Bay was formerly occupied by the large plant of a sand and gravel company which has been abandoned. The dredged channel extending from the southward in to the beach is no longer maintained.

Northport Bay is a large bay opening from the southeast end of Huntington Bay. The western part of Northport Bay has a good anchorage in 34 to 8 fathoms (6 to 15 m), and the eastern part in 8 to 11 feet (2.4 to 3.4 m). A shoal spot, with 13 feet (4 m) over it, and an obstruction, with 11 feet (3.4 m) over it, lie 400 yards northwestward and 750 yards north-northwestward, respectively, from the lighted buoy marking the entrance from Huntington Bay. This entrance is through a narrow, buoyed channel having a depth of 18 feet (5.5 m). The course through the middle of the narrow entrance to Northport Bay is 68° true (E. % N. mag.), passing 150 feet southward of the black buoys which mark its north side. From the inner black buoy a 51° true (NE. by E. 5% E. mag.) course will lead well northward of the red buoy, which marks the shoal extending 4 mile northward from Little Neck Point.

Centerport Harbor is a shoal bight in the south shore of Northport Bay just eastward of the entrance. A narrow, crooked channel, with a depth of about 3 feet (0.9 m), leads to the village of Center port. This channel leads a little eastward of mid-harbor in approaching the bare spit, which extends nearly across the bay, follows the north side of the spit at a distance of about 200 feet, curves around the southwest end of the spit, then follows its south side northeastward, and then trends southward somewhat eastward of mid-harbor. The tidal currents through the narrow channel at the end of the spit have an estimated velocity of 3 knots at strength.

Duck Island Harbor is a shallow cove on the north side of Northport Bay westward of Duck Island Bluff, which is the southwest one of two wooded knolls. There are depths of 7 to 9 feet (2.1 to 2.7 m) in the entrance, and 1 to 3 feet (0.3 to 0.9 m) in the upper part of the harbor. A spit, with 4 feet (1.2 m) on its outer part extends east-southeastward nearly across the entrance from Winkle Point. The range of a large tank on the north side of Duck Island Harbor, shut out by the trees on Duck Island Bluff, leads eastward of the spit, but the south side of Duck Island Bluff must be given a berth of nearly 200 yards.

There is a summer resort on Asharoken Beach, at the northeast end of Northport Bay, and a number of private boat landings at which the depth is about 3 feet (0.9 m).

Northport Harbor, at the southeast end of Northport Bay, has a depth of 10 feet (3 m) in the entrance, shoaling gradually to between 7 and 8 feet (2.1 and 2.4 m) abreast the wharves at Northport. Vessels select anchorage according to draft; the bottom is soft. During severe winters ice has been known to close the harbor for about two months.
