Think of camping on an outrigger dive boat in the tropics. There are four bunks on board below the main deck. Each bunk is good for two divers, so a maximum of eight divers can sleep on board. The whole bottom of the bunk is covered by one big mattress. There are some small shelves and nets for personal belongings. There are some small windows for fresh air. Another option is to take a mattress out on the webbing between the outriggers. You can sleep under the sparkling stars, if weather permits. There is only one bathroom on board the ship.
