If you want to explore the Gulf Islands, Sidney is a great town and place to provision. Anacortes is only 32nm to Bedwell Harbor, so going straight there for Customs then continuing on to Ganges is time efficient. Ganges is likewise a great little town with ample shopping for provisions.
Download map of Whiskey Golf for coordinate location and verify military operations for your crossing.
Strait of Georgia is crossed with a critical eye on the weather. If winds are calm, water flat, you can make a diagonal crossing from Porlier Pass to Secret Cove or Pender Harbor. Egmont or PLI next your choice.
Check with your Waggoner Crusing Guide to understand Malibu Rapids. Keep in mind your first time thru the rapids anticipation will be greater than the reality, but nonetheless, the slack times should be respected.
I can recommend staying at Backeddy Marina before PLI for a hike to Skookumchuck Rapids for a packed lunch. Very entertaining. Onto PLI (30nm) from Egmont is easier making the slack time, and your 2-3 days at Chatterbox Falls will be plenty of time to recuperate from your Skookumchuck hike!
Have fun!
