• If a boat’s centre of gravity (G) moves to a lower position:
• The point where the resultant of all the boat’s weights acts is the
• Before abandoning the boat it is advisable to…
• The satellite beacon works on:
• The radar transponder (SART):
• For distress, urgency and safety operations, the channel used is:
• The weather linked to a passing depression is characterised by…
• What phenomenon is the main cause of drift currents?
• When warm air advances and replaces cold air, the contact surface is called:
• The main wave parameters are:
• As to Dew Point, it is always reached when:
• As to absolute humidity, choose the CORRECT statement.
• A trough (vaguada) is:
• A RACON beacon provides:
• Besides changing the vessel’s speed, sea currents affect the course through:
• The “rain clutter” effect on the radar screen is due to:
• RASTER nautical charts (RNC):
• The total correction of the magnetic compass is defined as:
• The small circles of the Earth perpendicular to its axis are:
• If we sail to a place at longitude 70º W, what is its time zone?
• On 27 January 2025 on board the yacht La Savina the compass azimuth of Polaris is N 07º W (taken as at the Pole), sailing on true course 090º. Calculate the compass course.
• At HRB 15:30 in GPS position l: 36º 03' N, L: 005º 13' W with a West wind causing 10º leeway, you set course for Ceuta port green light (Ct = –5.5º). Calculate your compass course to Ceuta:
• At HRB 04:35 in GPS position l: 35º 58.0' N, L: 006º 00.00' W you head for Tangier port light at 7 knots engine speed in a current setting 110º at Ihc = 2 knots. Calculate your time of arrival at Tangier:
• On 27 January 2025 the yacht Noega leaves l=37º 32` N L=001º 06`W on true course 140º, total correction -5º, engine speed 12 knots. Calculate analytically the position and compass course after one hour’s sailing
• Sailing from GPS 38º 20' N, 000º 22' W to 38º 38' N, 001º 21' E on 28 April 2024, the yacht PUNTA PRIMA computes analytically the direct course and distance:
• At ship’s clock 10:30 we enter Tangier with a maximum draught of 2.40 m and are given a berth in the marina with a charted sounding of 2.50 m. From the current tide tables: nearest low water height 0.35, additive correction for the arrival interval 0.15 m. Calculate the water under the keel:
