Shaun,
We started and finished from Vancouver, BC, where we live and keep Papillon. We were not rushed and in fact, we spent a few days exploring ashore while we waited for better weather. The Admiral doesn't like beating in big wind, so when the gales were on the nose, we stayed in harbor. This is not to say that the weather was bad, in fact of the 4 days we saw gales on the Strait of Georgia, 3 were beautiful clear, sunny days. The one crappy day, we tried to motor the 45 miles to Comox, only to run for Gorge Harbor when our SOG dropped below 3 knots. What a fabulous misfortune, as this is one of the nicest places we visited. Awesome narrow entrance between rock cliffs, into a well protected anchorage. Fantastic marina and staff with a world-class West Coast restaurant where we gorged ourselves silly - and I thought the name derived from the entrance! I have attached a few pics to whet your appetite.
I hope that you can work out the timing, as it is truly one of the prettiest cruising grounds within reach of the PNW.
I have not been to the west coast of Vancouver Island and Barclay Sound. I think that Mark Reed and Vicki have done the trip a time or two. They, in fact have a great blog/website somewhere with a great diary of their circumnavigation of Vancouver Island.
