Thanks folks, for your input. Please forgive the grammatical errors. English is my second language (and for that reason I think I actually do a pretty good job
Interested people who contact me will have the chance to meet me and check the details, including my professional information, so forgive me for not posting my personal information online for the entire Internet community to see
For you to understand better: either I find such partner or I'll have to sell my boat and give up owning boats as I am getting way too busy for taking care of one. I could go that way and start chartering but I like to sail my own boat. I tried to hire people for such job but hired people, at least in Maine, are sometimes available and sometimes they are not. Also, professionals rarely take care of a boat like an owner, you know what I mean.
It may sound like an unfair deal to me, but considering that my boat is currently not used for at least 20 days a month during season, I would not lose much. It's true that wear and tear would increase but those are the expenses I plan to share with my partner.
It's true I'll have preference for chosing dates but considering my busy schedule I am pretty sure my partner will have plenty of options, and I plan to have some fair rules, like minimal period for giving notice of use, etc... For example, I have weekend call once a month and sometimes I travel, so those would be opportunities for the partner to use the boat on weekends. Please note I said "retired" person, exactly for our schedules not to conflict.
Minnewaska, thanks for your opinion, it would not work for you but I believe it's a fantastic offer for the right person. Especially if you consider I am not asking such person to pay for the boat initial cost.
It may sound hard to believe but I insist that interested people should check with me, one less skeptical person may be the lucky one
