When we had a share in a boat it had a better equipped galley than I have at home! There seemed to be a need for casseroles of every size and pots and pans abundant. The owners did decide that certain items were left on board and we all just renewed them as required - loo rolls, washing up liquid etc but again we tended to end up with several brands of everything as folk had their favourites. Having a share suited us when we were both working but it is, as others have said, nice to be able to leave your stuff on board and know it will be there when you go back. Also, we know that all the scrapes on our boat were put on by us and not by another owner who had a more cavalier attitude to care of the boat.
