Cruising US West Coast
The US West Coast runs from the protected mazes of the Pacific Northwest to the surf-lined beaches of Southern California, with Hawaii as the offshore prize. The San Juans and Puget Sound offer sheltered island cruising with big tidal streams; San Francisco Bay funnels the afternoon westerly; and the Channel Islands sit a day offshore from the Los Angeles sprawl. This region covers the Pacific coast from the Canadian border to Mexico, plus the Hawaiian islands, on survey-grade ENC.
