Tides And Currents

Question 1

Olympia tide

Answer 1

Mean- 10.5ft
Diurnal- 14.4ft

Question 2

Free floating logs

Answer 2

Be cautious of free floating logs and semi submerged deadheads or sinkers especially during freshets, after storms or unusually high tides

Question 3

VTS tidal broadcast

Answer 3

VTS Will provide a tidal broadcast when tides are predicted to exceed 10ft in Seattle. When tide exceeds 10ft in Seattle vsls should proceed at a safe speed to minimize the risk of wake damage

Question 4

Narrows current

Answer 4

Velocities can exceed 5kts at time. At the N end of the narrows the current sets N most of the time on the E side of the passage and S most of the time on the W side

Question 5

Hale pass current

Answer 5

Attains velocity in excess of 3kts at time. The Ebb is stronger than the fld

Question 6

Pitt pass current

Answer 6

Between key peninsula and McNeil island, connects drayton pass and care inlet. Only pass E of McNeil island is used by small craft with local knowledge. In this pass the ebb sets to the north and is stronger then the fld. Attains velocity of 2.5kts or more at time

Question 7

Drayton pass current

Answer 7

Estimated current velocities of 1-2 kts occur at the Sw end of the pass

Question 8

Steilacoom current

Answer 8

Tide rips occur in vicinity and can be dangerous to small craft

Question 9

Pickering pass current

Answer 9

Fld sets from case inlet toward hammersly inlet and the ebb in the opposite direction. Strongest currents are near the S end where velocities reach 2.5kts at times

Question 10

Peale pass current

Answer 10

Velocity can attain 2kts in narrow part of pass. Fld sets N and Ebb S

Question 11

Dana pass current

Answer 11

Currents frequently attain velocities of 3kts or more

Question 12

Squaxin pass

Answer 12

Tide rips can occur. Usual velocity is about 1.5kts
