• What two conditions must be met for a boat to be in equilibrium?
• Before abandoning the boat it is advisable to:
• Recommendations for safety equipment:
• If a helicopter rescue takes place:
• Mark the correct answer:
• The “amount of water in the air at a given moment expressed in grams per cubic metre of air” is…
• What are currents caused by density differences, from differences in temperature and salinity between waters in different places or depths, called?
• Condensation in a warm, moist air mass passing over a cold surface creates:
• The wind moving in a straight line from high to low pressure, at right angles to the isobars, is…:
• The small circle in the northern hemisphere at latitude 23º 27′ N is:
• The water track results from the action of:
• The equation for the compass total correction from the compass azimuth of Polaris is:
• Spanish nautical charts are kept up to date through:
• At HRB 0700 with Punta Europa bearing due North true at 9.3 miles, you steer Ra = 249º (Ct = 6º E) at 8 knots with a North wind causing 5º leeway. Calculate the HRB when Punta Malabata bears due South true:
• At HRB 1009, radar simultaneously indicates a distance of 5 miles to Cape Spartel lighthouse and 4 miles to Tangier port breakwater head lighthouse. Plot your position:
• At HRB 1124 you fix your position with Dv Punta de Gracia = N49ºE at 10.8 miles, then lose engine power in calm wind and drift for 2 hours in a current setting 112º at 2 knots. Calculate your position at HRB 1324:
• At HRB 1424 steaming into the current (Rc = 112º, Ihc = 2 knots) at 8 knots log speed, radar shows Cape Spartel lighthouse at true bearing Dv = 160º and distance 12.2 miles. Plot your position at 1424:
• At HRB 1524 in GPS position 36º 00.6' N – 006º 05.1' W, you set course for Barbate port (red breakwater light) at 8 knots in a current setting Rc = 112º at Ihc = 2 knots. Calculate your HRB of arrival at Barbate:
• At ship’s clock 17:10 after entering Barbate they tie up at the Marina waiting quay and are given a berth with a charted sounding = 2.50 m, the yacht’s draught being 2.50 m, and obtain from the current Tide Tables: nearest low water height = 0.87 m; additive correction for the arrival interval = 0.01 m. With this data they work out the water under the keel at the berth:
