What is the period of time around the 0955 (ZD +5) slack in which the current does not exceed 0.3 knot? #17 You want to transit Hell Gate, NY on 23 July 1983. What is the period of time around the AM (ZD +4) slack before ebb when the current will be less than 0.3 knot? #18 You will transit the Cape Cod Canal on 7 November 1983. If you arrive at the R R Bridge at 1655 EST (ZD +5), for what period of time during your transit will you have currents of not more than 0.5 knot? #19 You are bound for the Chelsea docks in the Hudson River. The Captain wants to arrive at the docks at the first slack water on 28 July 1983. You are keeping daylight saving time. What time should you be at the docks? #20 You want to transit Hell Gate on 23 July 1983. What is the period of time around the AM (ZD +4) slack before ebb when the current will be less than 0.5 knot? #21 You are on a coastwise voyage bound for Marcus Hook, PA. Your speed is 15 knots. You wish to use the flood tide to facilitate docking starboard side to, heading seaward. To have the most favorable tide throughout, you should time your arrival at the entrance to Delaware Bay __________. #22 Determine the time after 0730 EST (ZD +5) when the velocity of the current will be 2.1 knots on 26 March 1983, at Fort Pulaski, GA. #23 Determine the duration of the first PM slack water on 3 March 1983, east of the Statue of Liberty, when the current is less than 0.1 knot. #24 Determine the time after 0300 CST (ZD +6) when the velocity of the tidal current will be 0.5 knot on 16 April 1983, at Port Arthur Canal Entrance, TX. #25 The predicted time that the ebb begins at the entrance to Delaware Bay is 1526. You are anchored off Chestnut St. in Philadelphia. If you get underway bound for sea at 1630 and turn for 12 knots, at what point will you lose the flood current? #26 The predicted time that the flood begins at the entrance to Delaware Bay is 1526. You are anchored off Chestnut St. in Philadelphia. If you get underway bound for sea at 1600 and turn for 8 knots, at what point will you lose the ebb current? #27 The predicted time that the flood begins at the entrance to Delaware Bay is 1526. You are anchored off Chestnut St. in Philadelphia. If you get underway bound for sea at 1300 and turn for 13 knots, at what point will you lose the flood current? #28 The wind at Frying Pan shoals has been south-southwesterly at an average velocity of 30 mph. The predicted set and drift of the rotary current are 232° at 0.8 knot. What current should you expect? #29 The wind in the vicinity of Nantucket Shoals Light has been southerly at an average speed of 23 mph. The predicted set and drift of the rotary current is 225° at 0.8 knot. What current should you expect? #30 The wind at Frying Pan shoals has been west-northwesterly at an average velocity of 40 mph. The predicted set and drift of the rotary current are 323° at 0.6 knot. What current should you expect?
