To add to the above comments, it is probably unwise to sail through any of the smaller passes because you will impede the passage of everything else. You should motor through.

The correct timings and routes through the various passes are the subject of many books and articles. The foremost are probably the Sailing Directions. Many are available at local libraries. I find that they give good information on how and when to transit the passes. Pacific yachting recently did a series on all the passes right up to the north end of the Island. It was very good.
