Faster - great shot of Skookumchuck
I use the following guidelines for going through passes with a tidal current. The speeds are based on the maximum current on either side of the turn.
0 - 3 knots: anytime
3 - 6 knots: 30 minutes ether side of the turn
6 - 9 knots: 15 minutes and getting shorter
These are what I teach in coastal navigation. In reality we sometimes have to do otherwise. east of Campbell River, Yuculta Rapids, Gillard Pass and Dent Rapids have to be done one right after the other. We start through the Yucultas one hour prior to the turn to ebb and catch counter currents to carry us through. This way we get through Dent Rapids before a strong ebb develops.
