What’s New Spring 2021

Greetings from Petersburg, Alaska! Toni and I hope you are well and healthy. We are enjoying a few quieter days up here and this week Captain and Crew are in Wrangell having the Northern Song serviced before the summer starts.

Our Sitka Spring Herring trips were an exciting launch into the new season. Greeted with snowy weather, we saw some nice humpback whale bubble netting and eagle activity and are pleased to report that the  Sitka spring herring, which is a keystone species, had one of its strongest runs since Alaska Department of Fish and Game started gathering date back in the 1970s.

We are fully booked for 2021, but we do have one cabin available on our Focus on Whales trip with Jim Nahmens in July 2021. If you are interested, contact us quickly!

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…
