Itineraries will include no ports of call, only adventures.

The owner of luxury line American Safari Cruises has announced a new brand, InnerSea Discoveries, that will focus on adventure-minded vacationers.

InnerSea Discoveries is designed as a less expensive alternative to 12-year-old American Safari Cruises. The new line will operate two ships that have been out of commission for several years, the 80-passenger Wilderness Discoverer and the 66-passenger Wilderness Adventurer, which formerly belonged to Glacier Bay Cruise Lines. The vessels will undergo a top-to-bottom renovation before setting sail for the new line.

InnerSea Discoveries will offer seven-night voyages between Ketchikan and Juneau, but in an unusual twist, the sailings won’t include a single port call. Instead, the ships will spend the entire week exploring the tree-lined fjords and inlets of the mountainous Southeast region in search of wildlife and natural beauty. Nature guides stationed on the vessels will take passengers on frequent off-ship excursions on inflatable boats and kayaks to explore glaciers and icebergs, look for wildlife such as whales, bears and sea lions, and make landings for hikes through remote forests. Other adventure activities will include paddle boarding, snorkeling, “polar bear club swims,” fishing, birding and glacier walks. The line even plans optional overnight backpacking and kayaking outings from the ships.
