The floor was black, the portholes didn't seal shut, so when it was raining, water was dribbling in over the power outlet. Ex-trawler so it rolls like all hell. Treadmill in the forepeak but usually broken due to rolling, and you'd hit your head on the ceiling if you are tall. Nothing to do on down-time and the internet access is pitiful. Food quality was completely lacking, as was food hygiene - I got food poisoning. Heatwaves of over 35C and the AC was broken the whole time, was never fixed, so all the doors were open which meant that there were flies everywhere. At one point we were actually sweeping piles of flies up. Cabins were incredibly noisy when next to the steering gear, and there was black mould on the bulkheads. Dead flies squashed and dried onto the surfaces from god only knows when, and never cleaned. On the deck was black due to the soot, which would get tracked inside the vessel. Easily the filthiest vessel I've ever had the misfortune of working on.
