Google brought up this article in the Vancouver Sun. Not just a race, more an exploration of the island and communities. Perfect way to spend a couple of weeks sailing.
There's another interesting race that just started in Alaska. Any boat human or sail powered(or both), any size, from point A to B along the coast. At first it sounded hokey but after looking at the 'course', a mixture of open water and inland waterway, I can't think what boat I would chose. Unlike open water sailing, races like this tax sailors abilities for long distance in little or no wind.
