Hey Cascade-fixer: Just a thought regarding the "two's company - three's a
mob. The experience of our crowd, at least when involved in short cruises and weekending, involves the
concept of "critical mass". We always found that for two people to get along on the boat there has to be real strong feelings for each other, while 3 people have that critical mass that usually means more fun and flexibility. I don't really mean to argue, it is just that your comment brought back the memory of us always trying for "critical mass".
Please, no jokes about orgys or "menage-a-trois". Those were not part of the critical mass equations. Also, five days out, your opinion of the dynamics could easily be more correct.
I had real trouble with a four-person crew on a long journey. One guy took great delight in psychologically bullying one of the others; while the other two of us just couldn't get it under control. Definitely, group dynamics are really important.
Not that I am an expert, but I have come across advice proposing that boat co-owners should have long, complete, and
legal agreements regarding all expenses, use, and final dissolution of the
partnership.
