uch cases as are specifically provided or in the regulations in this section. All registered merchant vessels shall ass through the locks in the order diected by the superintendent. Other craft shall be allowed to pass through he locks at the discretion of the superntendent.

(i) Navigation of the locks. (1) All barges navigating the locks whether approaching or leaving the locks are required to be assisted by one or more tugs of sufficient power to insure full control at all times. All craft approaching the locks while any other Ivessel going in the opposite direction is in or about to enter shall be stopped where they will not obstruct the free passage of such other vessel.

(2) All vessels over 100 gross tons including those which are accompanied by towboats must attach not less than two good and sufficient lines, cables, or hawsers to the bollards or other fixtures provided for the purpose to check the speed of the vessel and to stop it as soon as it has gone far enough to permit the lock gate behind it to be closed. Each line, cable, or hawser shall be attended on board while passing into the lock by one or more of the vessel's crew. Where vessels are so long that in order to get them wholly within the locks it is necessary to go within 100 feet of the lock gate ahead, the speed of the vessel must be slow and the vessel must be fully under control at all times by the lines, cables or hawsers. All towboats and vessels less than 100 gross tons may enter the locks without having lines out subject to the discretion of the superintendent. The master or person in charge of a vessel shall arrange to have any line, cable, or hawser handed or thrown from the lock walls by the superintendent, or his assistants, made fast on the vessel as requested or directed, so that in cases of emergency such line, cable, or hawser may also be used to check the speed of and stop the vessel.

(3) Operators of vessels less than 200 gross tons may use the floating moorings in the large lock to fasten lines or hawsers, but they shall not be used to check the way on any vessel greater than 30 gross tons.

(4) Vessels less than 30 gross tons may fasten lines to the floating moor

ings in the large or small locks. All persons shall keep off the floating moorings at all times.

(5) No line shall be attached to anything on or a part of the dam except the fixtures provided for this purpose.

(6) Equipment of each craft shall include a sufficient bow line and stern line.

(j) Mooring. When a craft is in position in the lock, it shall be securely fastened in a manner satisfactory to the superintendent to prevent the craft moving about while the lock is being filled or emptied, and the lines, cables, or hawsers used for this purpose shall be attended as far as is necessary or required while the filling or empting is in progress.

(k) [Reserved]

(1) Signals. (1) All craft desiring lockage shall, on approaching the locks, signal by two long and two short blasts of a whistle or other sound device. Two long blasts from the lock in reply will indicate a delayed opening and direct the craft not to enter the lock.

(2) Lights are located at each end of each lock and will normally show red. No vessel shall come within 100 feet of the outside of any gate when the signal is red except when so directed by the superintendent.

(3) Fireboats and craft owned by the U.S. Government shall be given prompt and preferential lockage when they sound four long blasts.

(4) No vessel shall move into or out of any lock until the controlling signal is green. A green light in addition to audio loud speakers, operated by the superintendent or his assistants, will direct craft through the locks.

(5) It shall be the duty of every master or person in charge of any vessel to ascertain by personal observation that the lock gate is fully open before proceeding.

(m) Operating machinery. Lock employees only shall be permitted to operate the lock gates, signals or other appliances. No person shall deface or injure any part of the Amelia Earhart Dam, or any pier, wall or other structure or any mechanism connected therewith; nor shall any person, without the consent of the superintendent, make fast to the dam, guard, guide

wall, pier, or any appurtenance thereof any vessel, scow, raft, or float.

Where vessels are so long that in order to get them wholly within the lock it is necessary to approach within 150 feet of the lock gate ahead. the speed of the vessel must be slow and fully under control by the lines, cables, or hawsers. Steam vessels of more than 100 tons gross, not including towboats, will not be permitted to turn their propellers on entering the lock after the bow of the vessel has entered, but will be drawn in by means of capstans on the lock walls or otherwise, and their speed must be checked and the vessel stopped by lines, cables, or hawsers as in other cases. All steam vessels may leave the lock under their own power. The master or person in charge of a vessel shall arrange to have any line, cable, or hawser handed or thrown from the lock walls by the superintendent or his assistants, made fast on the vessel as requested or directed, so that in cases of emergency such line, cable, or hawser may also be used to check the speed of and stop the vessel.

(h) When a vessel is in position in the lock it shall be securely fastened in a

manner satisfactory to the superintendent, or his assistant in charge of the lock at the time, to prevent the vessel from moving about while the lock is being filled or emptied, and the lines, cables, and hawsers used for this purpose shall be attended as far as is necessary or required while the filling or emptying is in progress.

§ 207.20 Cape Cod Canal, Mass.; use, administration, and navigation.

(a) Limit of Canal. The canal, including approaches, extends from the Canal Station Minus 100 in Cape Cod Bay, approximately one and six-tenths (1.6) statute miles seaward of the Canal Breakwater Light, through dredged channels and land cuts to Cleveland Ledge Light in Buzzards Bay approximately four (4) statute miles southwest of Wings Neck.

(b) Supervision. (1) The movement of ships, boats and craft of every description through the canal and the operation and maintenance of the waterway and all property of the United States pertaining thereto shall be under the supervision of the Division Engineer, U.S. Army Engineer Division, New England, Corps of Engineers, Waltham, Massachusetts, or the authorized representative of the division engineer, the Engineer-In-Charge of the Cape Cod Canal. The division engineer or the Engineer-In-Charge from time to time will prescribe rules governing the dimensions of vessels which may transit the waterway, and other special conditions and requirements which will govern the movement of vessels using the waterway.

(2) The Engineer-In-Charge, through the marine traffic controller on duty, will enforce these regulations and monitor traffic through the canal. The marine traffic controller on duty is the individual responsible for interpretation of these regulations with respect to vessels transiting the canal. Vessels transiting the canal must obey the orders of the marine traffic controller.

(3) The government has tugs stationed at the West Boat Basin for emergency use on an on-call basis. A patrol vessel is manned and operational 24-hours a day.

(c) Communications. There is a marine traffic controller on duty 24 hours a day, seven days a week, in the traffic control center located at the Canal Administrative Office. The primary method of communications between the canal and vessels transiting will be by VHF-FM Marine radio. The traffic controller can also be contacted by telephone.

(1) For radio communications, call the traffic controller on channel 16 to

establish contact. The transmissions will then be switched to channel 12 or 14 as the working channel to pass information. Channel 13 is also available at the canal office; however, the use of channel 13 should be limited to emergency situations or whenever vessels do not have one of the other channels. All four channels are monitored continuously by the traffic controller. Radio discipline will be adhered to in accordance with FCC rules and regulations.

(2) For telephone communications with the traffic controller, call (617) 759-4431.

(3) Vessels shall maintain a radio guard on Marine VHF-FM channel 13 during the entire passage through the canal.

(4) All radio communications in the vicinity of the canal are tape recorded for future reference.

(d) Vessels allowed passage. The canal is open for passage to all adequately powered vessels properly equipped and seaworthy, of sizes consistent with safe navigation as governed by the controlling depths and widths of the channel and the vertical and horizontal clearances of the bridges over the waterway. The granting of permission for any vessel to proceed through the waterway shall not relieve the owners, agents and operators of full responsibility for its safe passage. No vessel having a greater draft forward than aft will be allowed to transit the canal. Craft of low power and wind driven are required to have and use auxiliary power during passage throughout the canal as defined in paragraph (a) of this section. Low powered vessels will be required to await slack water or favorable current for canal transit.

(e) Tows. (1) Tows shall be made-up outside the canal entrances. All vessels engaged in towing other vessels not equipped with a rudder shall use two lines or a bridle and one tow line. If the vessel in tow is equipped with a rudder or a ship shaped bow, one tow line may be used. All tow lines of hawsers must be hauled as short as practicable for safe handling of the tows. No towboat will be allowed to enter the waterway with more than two barges in tow unless prior approval is granted by the Engineer-In-Charge; requests must be

submitted 12 hours in advance of passage.

(2) The maximum length of ponter rafts using the canal will be limited: 600 feet, and the maximum width to feet. Pontoon rafts exceeding 200 fe in length will be required to have r additional tug on the stern to inst that the tow is kept in line. The the used must have sufficient power: handle the raft safely.

(3) Dead ships are required to trans the canal during daylight hours & must be provided with the number : tugs sufficient to afford safe passag through the canal. (A dead ship w not be allowed to enter the canal uless prior approval is granted by the Engineer-In-Charge; requests must be submitted 12 hours in advance of the passage).

(f) Dangerous cargoes. The master c pilot of any vessel or tow carrying dargerous cargoes must notify the Marine Traffic Controller prior to entering the canal. Dangerous cargoes are defined as those items listed in 33 CFR 126.10 when carried in bulk (i.e., quantities exceeding 110 U.S. gallons in one tank) plus Class A explosives (commercial or military) as listed in 49 CFR 173.53 (commercial) and 46 CFR 146.29-100 (military), liquified natural gas and liquified petroleum gas. Transportation of dangerous cargoes through the canal shall be in strict accordance with existing regulations prescribed by law. In addition, vessels carrying dangerous cargoes shall comply with the following requirements.

(1) They must have sufficient horsepower to overcome tidal currents or they will be required to wait for favorable current conditions.

(2) Transits will be during daylight hours.

(3) No transit will be permitted when visibility conditions are unstable or less than 2 miles at the approaches and throughout the entire length of the canal.

(4) Transits must await a clear canal for passage.

(g) Obtaining clearance. (1) Vessels under 65 feet in length may enter the canal without obtaining clearance. All craft are required to make a complete passage through the canal except excursion craft which may operate and

hange direction within the canal in Ccordance with procedures coordiated with the marine traffic conroller on duty. When the railroad ɔridge span is in the closed (down) posi

ion, all vessels are directed not to proseed beyond the points designated by stop signs posted east and west of the railroad bridge. Vessels proceeding with a fair tide (with the current) should turn and stem the current at the designated stop points until the railroad bridge is in the raised (open) position.

(2) Vessels 65 feet in length and over shall not enter the canal until clearance has been obtained from the marine traffic controller by radio. See paragraph (c) "Communications" for procedures. If a vessel, granted prior clearance, is delayed or stops at the mooring basins, state pier, or the Sandwich bulkhead, a second clearance must be obtained prior to continuing passage through the canal.

(3) Vessels will be given clearance in the order of arrival, except when conditions warrant one-way traffic, or for any reason an order of priority is necessary, clearance will be granted in the following order.

(i) First To vessels owned or operated by the United States, including contractors' equipment employed on canal maintenance or improvement work.

(ii) Second-To passenger vessels.

(iii) Third-To tankers and barges docking and undocking at the Canal Electric Terminal.

(iv) Fourth-To merchant vessels, towboats, commercial fishing vessels, pleasure boats and miscellaneous craft. (4) Procedures in adverse weather: Vessels carrying flammable or combustible cargoes as defined in 46 CFR 30.25 will be restricted from passage through the canal when visibility is less than 1⁄2 mile. Other vessels may transit the canal in thick weather by use of radar with the understanding that the U.S. Government will assume no responsibility: And provided, That clearance has been obtained from the marine traffic controller.

(h) Traffic lights. There are three sets of traffic lights showing red, green, and yellow that are operated on a continuous basis at the canal. The traffic

lights apply to all vessels 65 feet in length and over. The traffic lights are a secondary system that is operated in support of the radio communications system. The traffic lights are located at the easterly canal entrance, Sandwich, and at the westerly entrance to Hog Island Channel at Wings Neck. A third traffic light is located at the Canal Electric Terminal basin on the south side of the canal in Sandwich, and applies only to vessels arriving and departing that terminal.

(1) Westbound traffic. When the green light is on at the eastern (Cape Cod Bay) entrance, vessels may proceed westward through the canal. When the red light is on, any type of vessel 65 feet in length and over must stop clear of the Cape Cod Bay entrance channel. When the yellow light is on, vessels 65 feet in length and over and drawing less than 25 feet may proceed as far as the East Mooring Basin where they must stop. Prior to continuing passage through the canal, clearance must be obtained from the marine traffic controller.

(2) Eastbound traffic. When the green light is on at Wings Neck, vessels may proceed eastward through the canal. When the red light is on, vessels 65 feet and over in length and drawing less than 25 feet must keep southerly of Hog Island Channel Entrance Buoys Nos. 1 and 2 and utilize the general anchorage areas adjacent to the improved channel. Vessel traffic drawing 25 feet and over are directed not to enter the canal channel at the Cleveland Ledge Light entrance and shall lay to or anchor in the vicinity of Buzzards Bay Buoy No. 11 (FLW & Bell) until clearance is granted by the canal marine traffic controller or a green traffic light at Wings Neck is displayed. When the yellow light is on, vessels may proceed through Hog Island Channel as far as the West Mooring Basin where they must stop. Prior to continuing passage through the canal, clearance must be obtained from the marine traffic controller.

(i) Railroad Bridge Signals. The following signals at the Buzzards Bay Railroad Bridge will be given strict attention.

(1) The vertical lift span on the railroad bridge is normally kept in the

190-124 D-00--2
