Built in 1987 at Hamilton Ontario by Hank Hinkley and a Canadian Partner, Seaburban is an OCY 45. Based on the Reliance 44 hull, she’s a go-anywhere Cruising Club of America design by Pierre Meunier that has proven herself over the Atlantic and Pacific Oceans as well as the Gulf of Alaska and Bering Sea. Sister-ships have sailed over every ocean on the globe.

The Skipper

Soldier, citizen-scientist, serial entrepeneur and adventurer, Seaburban’s skipper is a one-man force. Not likely to take no for an answer and quick to quip, Bert is happiest aboard and abroad.

The Challenge

Simply stated, the goal is to sail non-stop, single-handed around the world via the 5 great capes using only a sextant, pen-and-paper, and log tables for navigation. Prior to 2020 only 7 people have accomplished this feat. The first is Sir Robin Knox Johnston in 1969 after completing the first Golden Globe Race. Second is Bernard Moitessiere who also competed in the 1968 Golden Globe Race. Third is Chay Blythe in 1971. Lastly, the 4 finishers of the 2018 Golden Globe Race Jean-Luc Van Den Heede, Mark Slats, Uku Randmaa, and Istvan Kopar.

Although there have been many exceptional solo-circumnavigations by North American sailors, before 2020 no North American has completed a solo-circumnavigation of this sort. I am the first.
