With that short of time frame mmurphy is correct in steering you to the Gulf Is. The time needed to get to the port of departure is a factor. Some may involve float planes or ferry trips that can easily soak up 6 to 8 hours each way from the Vancouver or Seatac airports. And the JetBlue flight will be at least 5 hours!! <g>
I second Sydney, but also look stateside at Anacortes or Bellingham. Take a look at the online editions of 48 North (www.48north.com) for a listing of charter operations on both sides of the border.
I am a commuter sailor with my favorite months being September to November.
