What’s New

We have just wrapped up our popular Sitka Spring Herring Extravaganzas. We had some blustery weather that is now feeling more springlike and during our Sitka trips we shared some wonderful whale activities with our enthusiastic guests. The Northern Lights were wonderfully active and thanks to some clear evenings our guests, guides and crew captured some stunning imagery of them.

We are pleased to announce that we have a new chef and crew for the 2022 season. Chef Stuart Anthony hails from Florida and will be bringing years of experience to the Northern Song galley. Captain and First Mate James Begeman and Naturalist Mindy Huston will be on board with Captain Dennis sharing their expertise and knowledge of our regional humpback whales.

Our 2023 cruising schedule has two custom charters available for April and this is a wonderful time of year to see the humpbacks, herring spawn, bears, and eagles.

A Family Testimonial from the Summer 2020!

How could we be so unbelievably BLESSED to have experienced this voyage on NS amid such a crazy time?  If you have to quarantine, this is for sure the place to do it! We have all been in awe of this amazing crew-top of the line knowledge, experience, warmth, generosity, talent! From start to finish we could ask for nothing more, except perhaps more time…
