Mark Gallick joins me onboard Ocean Gem for a 600nm ocean passage from Hamilton Island to Southport in Queensland. Its a challenging passage that takes in islands, reefs, whales, commercial and military traffic and a number of navigational challenges including the shallow 70nm passage down the western side of Fraser Island, the largest sand island in the world.

Mark shares the personal goals he wanted to achieve on our voyage south and his future plans for acquisition of a Seawind catamaran to go cruising with his family. We dive into Mark's 22 year career with the US Coast Guard including some colourful stories and being stationed on the US mainland, Hawaii and the Bahamas.
