How to find a partner
Partnerships are a very tricky business and boat partnerships make a marriage seem easy. My best advice is to pick someone that you have known at least 10 years, consider to be one of your best friends, have had several business deals and at least one that got a little dicey, who is at least as good a sailor as you are and who you have sen maintain a boat and taht this person is as fastidious as you or more, and who you would turn over your first born kid to. Then and only then, once you have found that person perhaps begin a dialogue with that person on the subject of a partnership.
Anything less, forget about it.
