A host looks after the guests and the boat, so you can relax. The exact tasks depend on the boat and the trip, but a host usually:
- prepares meals, typically breakfast and a light lunch
- keeps the boat tidy, with everything in its place and the shared spaces clean
- helps the skipper with maneuvers and mooring, for example handling lines when docking
What a host does not do
- The host does not enter your cabin. Your cabin is your private space.
- The host does not make your bed in the morning. Fresh bed linen and towels are available on request.
Your host needs meals and a berth too: see Do I need to provision the skipper/crew? and Where does the skipper or crew sleep?
