Q

⟡In Long Beach, where might one experience bank cushion and suction, and how can its affects be reduced?

A

A pilot in the port of Long Beach can expect to encounter bank cushion and suction in the Back Channel. Reducing speed will reduce the effects of bank cushion and suction. To keep the vessel in the channel, a pilot may also employ the help of the rudder, by steering slightly toward the closest bank to counteract the bank cushion effect on the bow.

Q

⟡You are on an inbound ship within 1nm of Queens Gate and observe a fleet of sailboats moving eastward approaching the number 3 buoy and hoisting their spinnakers and it appears they will continue east towards the Delta anchorage. What should you do?

A

The sailboats should keep clear of a vessel that can only maneuver in a narrow channel, as per Inland Navigation Rules, Rule 9 (as noted in Note C).
If your vessel is in doubt as to whether the actions of the sailboats are taking sufficient action to avoid collision, your vessel should sound 5 short blasts and if necessary to avoid collision shall slacken her speed or take off all way.

Q

Describe the limitations on traffic passing through the Henry Ford and Commodore Heim Bridges over Cerritos Channel.

A

The narrow channel width combined with restrictions on passing under the drawbridges limit traffic through Cerritos Channel to pleasure vessels, tugs without tows and tugs with tows alongside or pushing ahead. However, tugs with bunker barges frequently pass under the bridges. Small size tankers occasionally pass, given appropriate weather, vessel draft and trim and maximum beam.

Q

What is a Tsunami? What would you do if a Tsunami warning was issued?

A

A Tsunami is a large wave caused by a submarine earthquake. They are waves characterized by long wavelength and high rate of speed. The first wave or surge will cause a recession of the water from the shore. A tremendous oncoming crest will follow this recession. If time allows put to sea and head for the nearest deep water. If caught in port it is difficult to avoid damage.
