On the heels of a sold out inaugural season in Alaska, InnerSea Discoveries has announced the acquisition of the 76-guest Wilderness Explorer, formerly the 86-guest Spirit of Discovery.

After significant renovations, the ship will sail active, adventure un-cruises between Juneau and Sitka, Alaska beginning summer 2012.

“There’s no doubt about the demand for active, hands-on explorations in Southeast Alaska,” said Dan Blanchard, principal and chief executive officer of Wilderness Explorer.

“We quickly sold out our first season.

“This ship fits in nicely with our fleet, and we are starting renovations now to add new amenities and spaces fitting our style of active adventures.”

Beginning June 2nd, 2012, the Wilderness Explorer will sail weeklong un-cruise adventures between Juneau and Sitka, Alaska with three days spent exploring inside Glacier Bay National Park.

A National Park Ranger will stay aboard the ship for the full three days to provide interpretation on the area’s history, culture, geography, flora and fauna.

The park ranger, along with shipboard expedition guides, will also lead guests on hiking and kayaking expeditions within Glacier Bay. Other areas to be explored include Icy Strait, Chichagof Island and Peril Strait.

In May and August, two-week cruises between Seattle and Juneau (and reverse) will be offered.
