Q.1) A vessel while steering a course of 232°(T) observes the following bearings of Utklippan Lt. (55°
57’N 015° 42’E), 1900: 282°(T), 1930: 311°(T), 2015: 023°(T). If the current is known to be setting
020°(T), find the position of the vessel at 1900 and 2015 hrs. Also find the course and speed made
good.

Answer:

1900 Hrs. – 55°55.5’N; 015°55.3’E
2015 Hrs. – 55°52.5’N; 015°38.2’E
CMG – 252°T
SMG – 8.1 Kts

Q.2) While steering 349°(T), SVANERE lighthouse (55° 08’N 15° 10’E) was sighted at 2000 hrs, the
visibility was restricted to 5’ only and the current was setting 278°(T) x 3 knots. At 2100 hrs, due to
failure of main engine vessel stopped instantaneously. At 2300 hrs, HAMMERODDE light (55° 18’N 14°
47’E) was sighted. If the current had been constant throughout, find the vessel’s position at 2300 hrs.

Answer:

2300 Hrs Position – 55°28’N; 14°27.2’E

There is an error in the question — the 2000 hrs position falls on land

The vessel is a deep draft tanker and has to pick up Pilot off Kullargrund Lt Ho (55° 18’N 013° 19.4’E) at designated Pilot stn.
