Seymour Narrows is a bit of water one approaches with caution. This narrow passage north of Campbell River provides the shortest route between Vancouver Island and the mainland for transiting vessels. This passage is also subject to dramatic tidal currents of up to fifteen knots.

The strong currents create large areas where the water seems to boil, dotted with whirlpools and debris swept along by the rushing water. The result is what explorer Captain George Vancouver described in his logs as “one of the vilest stretches of water in the world.”

As usual we had anchored and waited a couple hours for the tide to change, waiting for the worst of the currents to slack. While small, fast boats can pass by during high current, most vessels wait for the tide here. We were not alone, when we pulled anchor and nosed into the narrows we joined a parade of boats that had waited.

The passage was once much worse, a large rock named Ripple Rock lurked just under the surface at low tide. This mid channel rock created huge standing waves and vicious eddies as the current ran over it.
