Kolive and Northern Spy - thank you so much for the links. I do much better with visual overviews than just reading a list of chart titles.
I'm thinking that these 4 will provide me coverage of the Vancouver Island coastline as well as some overlap as I get closer to DS:
3512 - Strait of Georgia - Central Portion
3513 - Strait of Georgia - Northern Portion
3538 - Desolation Sound and Sutil Channel
3539 - Discovery Passage
I'm up at work so don't have my chart books handy to do a thorough check. I'd like to order what I need so they're waiting for me to drool over when I get back to the boat next month.
