Captain Jon Keller is a U.S. Coast Guard licensed sea captain with decades of experience on boats of all kinds.  He grew up sailing on Lake Winnipesaukee in New Hampshire, then fled to Montana to go to college, grad school, and to ultimately work as a wilderness guide.

​​

His sailing--most of it single-handed--has ranged from the Bahamas to far Downeast Maine.  Much of his life has been spent living aboard boats, working on boats, writing about boats, and recreating on boats.

​​​

Early in his career, he trained to be an At-Sea Monitor for NOAA in the Gulf of Maine groundfish industry--which included a host of maritime safety courses and certifications--but quickly returned to his home waters Downeast.

​​​

Back home, he worked as a sternman for a top-tier  lobsterman who became a mentor; he taught Jon the local waters, ecology, history, and culture.  Jon then shifted to work as a commercial clam digger, author, and sailor.​

​​​

Jon Keller's first novel, Of Sea and Cloud, depicts life in a small, working harbor.  His essays have appeared in Cruising World, Downeast Magazine, the Island Journal, and many others.

In 2023, Capt. Jon founded Polaris Charter Company, thus combining his love of the Downeast coastline with his unique knowledge base, wide range of experiences, and passion for education.
