- By definition, an isobar is:
- Wave period means:
- In the Canary Islands the general current usually sets:
- On surface isobaric charts, what shows the pressure gradient?
- Waves seen from the coast but generated far away are called:
- The Euler wind has a direction:
- Heading for the Strait of Gibraltar, 3 miles off Cabo de Gata, bearing in mind the Strait current, we should:
- What is an ENC (Electronic Navigational Chart)?
- The chart carriage requirement states that:
- AIS is a data-transmission system working in which band?
- Choose the CORRECT statement about magnetic variation:
- The Automatic Identification System (AIS):
- Determine the compass course (Ra) to sail from Algeciras port breakwater red light to Punta Almina lighthouse with an easterly wind causing 4° leeway (deviation –5° and chart variation for the year 2020):
- From l = 44°-36.5' N and L = 001°- 15.5' W, we sail on direct course 239° for 125 miles. Calculate the dead reckoning arrival position by rhumb line.
- With initial position l=36º05´N and L=006º15´W and final l=34º32´N and L=009º46´W, find the direct course and distance between them.
- Steaming on true course 258° at 10 knots, you take true bearing Dv Punta Carnero = 321° at 02h 30m and Dv Punta Carnero = 020° at 03h 00m. Calculate your position at 03h 00m:
- At Hrb 17:42, 7 miles due West true of Cape Spartel lighthouse, a vessel steers Ra = 030º at 12 knots (Ct = –5º); at Hrb 19:02 it fixes its position on the Punta de Gracia–Spartel opposition at 9.4 miles from Punta Paloma. Find Rc and Ihc:
- Steering compass course Ra = 250° while on the opposition line of Punta Carnero and Punta Cires lighthouses, you take a relative bearing (M) of 049° to Punta Cires lighthouse. Calculate the total compass error (Ct):
- In a current setting 200º at 3.5 knots, from the Punta Paloma–Punta Malabata opposition at 6.4 miles from Punta Paloma you head to pass 7.1' off Cape Spartel (Ct = +3.5º, engine speed 11.2 knots). Find Ra and Vef:
