Please also consider the physical condition your crew. You might want to give duties which require some strength or quick reactions to people who are up to it. For example handling mooring lines.
Not everybody has the necessary physical strength and quick reactions.
Duties such as throwing the stern lines or tying up fenders don’t require strength
Maybe the fender job would be good for the ones who rather like it relaxed and prefer doing things in their own time.
For the ones who don’t like to be active on deck at all, there are always things below deck, i.e. opening and closing seacocks, or control of the battery voltage for instance.
Don’t leave anybody out, make them all a contributing part of the team.
The more you adapt the duties to the preferences of each person on board, the more you will enjoy your sailing holiday as a team.
