After a day of scenic cruising the majestic Misty Fjords and the Grenville Channel, the next morning we entered the Queen Charlotte Strait and on into the 274-mile Inside Passage that stretches from Prince Rupert in northern British Columbia to Port Hardy on Vancouver Island. Many places along British Columbia's Central Coast are still only accessible by the BC Ferry system. We continued into the Johnstone Strait located on the northern coast of Vancouver Island which consists of a number of sharp turns, a combination of currents and rocky shores. Johnstone Strait is also well known for its killer whale pods. We eventually approached the Seymour Narrows, a very narrow passage with tidal currents up to 16 knots, which can only be navigated during 'slack' tides. In 1958, a huge dynamite blast removed Ripple Rock, located in the middle of Seymour Narrows, which sank at least a vessel a year before its removal.
