The Seymour Narrows is a 3-mile/5 km stretch of the Discovery Channel north of Vancouver Island, British Columbia that is notorious for the strength of the tidal currents flowing through it. The average width of the narrows is just 750 meters. During extreme tides, the current through the narrows is subject to severe Venturi effect, resulting in an increased velocity that can reach 15 knots. For much of its modern history, there was an additional hazard in the narrows called Ripple Rock, a shallow obstruction that claimed no fewer than 119 ships and 114 lives. In 1958, after months of tunneling and preparation, Ripple Rock was blown up in the largest commercial, non-nuclear explosion ever recorded in North America. Still, the navigation of Seymour Narrows is dependent on tidal and other conditions, and requires skill and technical accomplishment.

The Queen Charlotte Sound lies between the Queen Charlotte Strait, which winds between Vancouver Island and the British Columbia mainland in the south, and Hecate Strait, which is northward, adjacent to the Haida Gwaii Islands off the Pacific coast of British Columbia. It is a broad reach in the long shipping route called the Inside Passage threading the myriad islands stretching from Washington’s Puget Sound to Alaska.

In the passage between Sumner Strait and Clarence Strait in Southeast Alaska’s Alexander Archipelago, midway between Price of Wales Island on the west and Zarembo Island on the east, is a small cluster of islands with a picturesque passageway between them called Snow Pass. It makes a scenic up-close route for your Seabourn ship during the transit.

Decision Passage is the western end of the Sumner Strait, which runs through the Alexander Archipelago into the Pacific Ocean in Southeastern Alaska, bounded on the north by Kuiu Island and Cape Decision, the location of a 1932 lighthouse. This is the route your ship takes when coming from or going to the colorful historic community of Sitka on the west coast of Baranof Island, which was originally the Russian fortress town of New Archangel.

The Hubbard Glacier is the largest, and one of the most spectacular tidewater glaciers in North America. Its ice cliffs, some 400’ (121 m) tall, calve icebergs into the fjord, which may frequently be larger than a five-story building. The glacier’s surface is creased and contorted, resembling the wrinkled skin of a giant elephant. Records show it has been growing in thickness and advancing since 1895. This stands in stark contrast to other glaciers around the world, most of which have been receding during the past century. In 2002, the glacier blocked Russell Fjord for two and a half months, raising water levels 61’ (18 m) and threatening local communities with flooding. Nutrient-rich waters along the glacier face attract many species. Gulls and kittiwake colonies adorn smaller islands and harbor seals patrol the icy waters. In 1890, Israel Russell explored the area of Yakutat Bay and Hubbard Glacier, naming it after Gardiner G. Hubbard, a financier of his expedition and a founder and the first president of the National Geographic Society. VIEW CRUISES

Lynn Canal is a 90-mile long inlet into Alaska’s coast running from the Chilkat River in the north to the Chatham Strait and Stephens Passage in the south. Because it connects the towns of Skagway and Haines to Juneau and the rest of the Inside Passage, it is an important shipping lane for ferries, cargo and cruise ships, and was a crucial passageway to the Klondike gold fields during the Gold Rush. It was discovered by Joseph Whidbey in 1794 and named by George Vancouver after his birthplace, King’s Lynn in Norfolk, England. More than 2,000 feet in depth, it is one of the deepest and longest fjords in the world, and the deepest in North America outside Greenland.

One of the straightest stretches of the Inside Passage is the Stephens Passage just south of Juneau, a 105-mile channel between 5,000-foot peaks that cuts through the Alexander Archipelago between Admiralty Island on the west and the mainland and Douglas Island on the east. It is a good place to be on deck, because Admiralty boasts more bears than people, and the spruce and hemlock forests come right down to the water. The Passage is generally considered some of the best whale-watching water in Alaska, and also holds plentiful populations of huge Steller sea lions, as well as flocks of gulls and guillemots that clatter aloft as the ship passes. The passage was named by George Vancouver in 1794 after being charted by Joseph Whidbey.

Stikine Strait is a picturesque channel in the Alexander Archipelago of Alaska between Zarembo Island and Woronkofski and Etolin Islands near the mouth of the Stikine River south of Wrangell. It first appears on an 1848 Russian chart as Stakhin Strait and has been spelled variously on many charts since that time.

Misty Fjords National Monument is a section of the Tongass National Forest in Alaska’s extreme southeastern Panhandle region. The monument consists of over two million acres of deeply cut fjords cradled in U-shaped valleys between mountain ranges rising 2,000 to 3,000 feet above sea level. The fjords themselves extend as much as 1,000 feet below the surface. These granite ranges are covered with virgin forest, and most of the monument is also a dedicated wilderness area. Misty Fjords inspired the explorer John Muir to proclaim them among the most beautiful places he had ever seen. Your ship will cruise among these spectacular forests, waterfalls and mountains. The onboard Ventures by Seabourn team will offer optional excursions including kayaking the fjords and a short sightseeing floatplane flight.

Grenville Channel is a long, well-protected channel along the northern British Columbia coast between the large Pitt Island and the mainland. It is an important shipping lane, and you are likely to see ships of many different types and sizes as you pass through. The shores are mountainous on both sides, with two notable peaks about halfway through, Mt. Batchellor on the east side and Mt. Saunders on Pitt Island to the west. There are a number of Indian Reserves and Marine Parks in the mountains and narrow waterways off the channel.

The Princess Royal Channel separates the largest island along British Columbia’s coast from the mainland. It is located roughly halfway between Bella Bella in the south and Prince Rupert in the north, in one of the province’s most remote areas. Princess Royal island was named in 1788 by Captain Charles Duncan, in honor of his ship, the Princess Royal. The island is uninhabited, although there are two small villages in the channel, the First Nations community of Klemtu on Swindle Island and Hartley Bay on the mainland. Wildlife, by contrast, is plentiful, including Kermode, black and grizzly bears, deer, wolves and foxes. Golden and bald eagles nest in the region, as well as the endangered marbled murrelet. In the waters, there are abundant salmon, elephant seals, whales, orcas and dolphins.

Whale Channel is a picturesque waterway separating Gil Island from Princess Royal Island in British Columbia’s Inside Passage. Surrounded by snow-capped mountain ranges and teeming with marine life, It is a diversion from the main shipping lane, located roughly halfway between Prince Rupert and the First Nations village of Klemtu.

Johnstone Strait is a well-protected shipping route passing 68 miles/110 km along the northeast shore of Vancouver Island between the island and the mainland of British Columbia. The strait is between 1 ½ miles and 3 miles wide, and leads from the broad Georgia Strait through a narrow channel called Discovery Passage. The strait was named by Vancouver in 1792 for James Johnstone, the master of one of his tenders during the survey expedition that revealed Vancouver Island to be an island. There are no cities or towns on the strait. The Johnstone Strait is the summer range of a large pod of seasonally resident orcas which are frequently seen in the area.
