Current was known to be setting S'ly @2 kts. Determine ship's position at 1800 & 1900 hrs, Gyro error 1°(H).

Following courses and distances were steamed by a vessel doing 12 knots, between noon of 1st Feb till noon of 2nd Feb. The noon position on 1st Feb was observed to be 15°N 30°W

Ship's Time | Compass Course (deg) | Variation (deg) E/W | Deviation (deg) E/W

1200 - 1800 | 175 | 3°E | 2°E

1800 - 2400 | 133 | 3°E | 6°W

0000 - 0600 | 090 | 3°E | 3°W

0600 - 1200 | 061 | 3°E | 4°W

Clocks were advanced for 1 hr at between 0300 hrs. Current setting 240° x 2 kts was experienced throughout. Estimate the noon position arrived on 2nd Feb when above courses were steered and distances steamed.

Calculate the Great Circle Distance, initial & final course between 33° 45'S, 23° 18'E and 20° 08'S, 104° 06'E.

For port of Antwerp (Vol. 1) on 9th March 1992, determine height of tide at 1541 hrs LT.
