Here's a real bone ... Not sure if it applies this time of year, straight out in front of HMCS Quadra, you can see the slope on sounder in 90'-110' of water, try and drop trap midway. Drop trap on a good tide change, and keep your eyes on it. If your into red rock crab, out in front of kingfisher is plentiful.
Avoid the ferry hole @ denman, much more productive spots on other side of island, check a chart and look for likely suspects.
