This is old news by now - we went a year ago, but I finally have my trip notes up - for the trip down and two weeks through the islands only. Maybe by NEXT year I'll get the return trip documented!

We sail in Phoenix - a steel Ohlson 41 sloop built in 1967. This July we're sailing from Bellingham into the Canadian Gulf Islands, maybe as far as Desolation Sound, but also planning to hit Lasqueti where we have a cabin. We've never sailed into the marina near our cabin before... I ordered the Canadian Hydrographic Charts for Vancouver East side - I ordered them from Maryland Nautical which seemed to have slightly better prices. Still runs $170 or so for that half, the same for the outside of vancouver island.
