Named by Vancouver in 1792, who took the water beyond it for a bay until Joseph Whidbey found the passage and proved Whidbey an island, hence the deception. The bridge that now spans it was built in 1935 and made the island a drive rather than a ferry. Anchorage: Anchor in Bowman Bay or Cornet Bay and wait for slack. Nobody lies in the pass. Hazards: The tide runs to 8 knots through a gap 150m wide, with whirlpools, overfalls and standing waves against the wind. Transit at or near slack water, calculated, not guessed. Divers here work slack only. Altro
