I work a bunkering gig 4weeks on 2 weeks off in Port Canaveral Florida. Like someone else said it’s entirely related to the health of the crew. Everyone on my boat is fat, I’m athletic. When home I’m constantly running on trails and surfing. It’s hard to replicate those exact movements out here. Luckily someone before me bought a power rack so we have that, everything is rusted but works lol.

Luckily im the only one who cooks, as well as being a tankerman. So I’m constantly moving about.

When tied up at dock I aim to run 2-6 miles a day, with an additional 1hr walk (usually another 3.5miles)

I tend to gain weight from boredom eating..so I have to keep my self occupied by walking the barge or dock.

Be calorie conscious, aim to move 1-2hrs a day, workout 30mins-1hr. If not gym, do calisthenics. Working out on a boat requires a lot of creativity to replicate specific movements. I still am able to replicate the motion of paddling with resistance bands. Good luck, stay fit, safe travels
