New Zealander Greg Landreth and Canadian Keri Pashuk are no strangers to adventure.

For 24 years the husband and wife duo have been living on a sailboat. They’ve traveled thousands of nautical miles into some of the coldest and most remote places in the world.

Pashuk is a photographer and Landreth is a mountain climber. They married in 1990 and since then, they have lived life at sea aboard the “Nothanger.”

Originally, their idea was to run away and climb mountains in Antarctica.

The dynamic pair has visited dozens of remote communities, photographed sea life and summated peaks never reached before.

On Friday, they anchored in Halifax’s North West Arm for a three-week refuelling stop on their way south from Greenland.

Their steel boat is new to them. They picked it up in August and have been sailing ever since. They bought it for the purpose of taking researchers, photographers and scientists to areas not always accessible by large ships and ice breakers more commonly used for remote research.

“It's the beginning of something very new and exciting,” says Pashuk. “Not only do we want to just do adventure, but we want to bring the science and education into it and try to get young people out there to see all the things we've been able to see.”

The adventure is evolving into a mission. The couple wants to help preserve the pristine areas they can’t get enough of.

“What I would like to do is use all of the aptitude that I have gained and experience I have gained and turn that into the service of humanity because I believe we can use that to move forward to make a better world,” says Landreth.

In 24 years they have retraced some of their travels, but they’ve never looked back. They say their sights are always set on the next horizon.
