Q

You are on an inbound ship within I nm of queens gate and observe a fleet of sailboats traveling eastward approaching the number 3 buoy, and hoisting their spinnakers and it appears they will continue east towards the delta anchorages. What should you do?

A

The sailboats are to keep clear of any vessel that can only safely navigate a narrow, as per rule 9 and the charted note c also slow the vessel to allow more time to asses the situation if the sailboats are not following the rules and to allow the sailboats to safely pass ahead is the prudent mariner to avoid a close quarters situation

Q

During what season does the Santa Ana wind blow

A

The Santa Ana is an offshore dessert wind occurring near San Pedro during the fall and winter whenever a strong high pressure sets over the so cal region and generates a NE to E’ly flow.

54
Q

To determine size of escort tug needed for a latent tanker you should use the following tug selection matrix.

A

All laden tank vessels entering the port should ensure proper implementation of the displacement ton tug braking force table. In addition to meet the requirements of the tug force selection matrix, tractor tug shall be tethered inbound and outbound. Conventional tugs may be tethered or untethered inbound but shall be tethered outbound. Tank vessels shall not proceed closer than two nautical miles from the federal breakwater entrance unless prescribed tugs are in position at the southern boundary of the pilot operating areas. Master shall ensure that the anchors are ready for letting go prior to entering the pilot operating areas.

55

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