Delayed departure

I found crew - the wonderful Liz Baldo and husband Henri Louis who are available from Oct 22 to Nov 9. The weather on Sunday was a little too rough, so we planned to meet at the boat after work Monday to depart. We stow gear, do a walkthrough of the boat, start the engine and get ready to depart. Henri notices a engine warning light and after a brief investigation we determine that the alternator is not charging the batteries. So no departure that evening. Luckily (?) last year we had alternator issues and purchased a replacement as well as rebuilding the failing one. We were currently running with the rebuilt alternator - so there was a brand new one available to be installed! Since it was late and we were not going to be able to depart that evening, we postponed any furthur repairs and got some sleep.
