This is a joint business venture. Treat it so.
Wait, I'm having a flashback: Ricky, Lucy, Fred and Ethel go in together on a diner…You have to run this like a business in some respect, and formalize some things. Since you mention rotating the use, you might be able to avoid some of the pitfalls by:1) Agree upon and create on paper two lists: a pre-sail and post-sail checklist (check oil, rigging, seacocks, washdowns, etc.), and a housekeeping check-out list that each couple follows before leaving the boat, and post them in the saloon (like a timeshare). This way, the boat is in agreed-upon condition when the next couple boards the following weekend. A log book that entries can be made in concerning developing conditions might also be wise to keep everyone "in the loop" and keep all issues out in the open ("lost winch handle over the side, will replace. John," or "throttle lever sticking, sprayed w/ lubricant") so no one can conveniently ignore them might also be wise, and will encourage others to find other small maintenance chores to accomplish and write in the log.2) Agree upon a regular amount to be contributed (perhaps quarterly) by each couple into an account that will cover slippage/mooring/storage, charts, routine maintenance and long-term replacements (if this were child support, it would be a "shoes today, college tuition someday" mindset). Be liberal so that there is always a funded kitty; something unexpected will come up, and then you'll be glad the money is already there to address it). "Lock" a slowly growing amout of this fund for eventualities like sails/repowering, so that you can't fall to the temptation to spend it on routine mainenance once it gets to be sizable. Decide beforehand how often scrubs, waxes, oil/filter changes, etc. will be performed. Better to have the money for a haulout/bottom job and decide it's not necessary than to pass the hat around to get it done a season late. The best accountant keeps the books/receipts and arranges for the routine service, and shows the ledger to the other partners often (at least at an annual/seasonal "business meeting"), so that everyone knows what's going on and is responsible for knowing. Bigger and/or infrequent jobs, like replacing sails cushions, canvass, or a tired engine, can be debated among yourselves, but the agreement will come easier if there is already money in the account. Everyone needs to buy into the idea that he will be putting money into this venture on a regular, rather than an ad hoc, basis.3) If any of the partners performs a significant maintenance task (a bottom scrub, or oil/filter change, say) instead of hiring out, all parties must agree to it, and agree to pay that partner for his time out of the maintenance fund, at whatever going rate can be agreed upon, just as a professional would be paid. This sounds silly on the surface, but what it does is recognizes the value of effort/expertise of the partners and prevents resentment festering because of unequal input. You'd pay for it anyway: you might as well pay it in a way that makes partners feel valuable and appreciated. The accountant takes a small stipend for his sevices, as well. Don't underestimate the psychological value of this practice.4) Equipment upgrades are trickier, because less agreement will arise about what to install on the boat. Agreeing on a philosophy (preferably a minimilist philosophy) beforehand will be important. A pre-arrangement that those items need to be agreed upon unanimously is probably better than letting 2 partners outvote the third, which will likely sew seeds of resentment (if one partner is forced to pitch in for a headsail furler he didn't want, you he'll fume everytime he uses it. OTOH, if everyone thinks that a cockpit table is a great idea, no problem. Safety equipment replacement should be discussed at the annual/seasonal business meeting.Some equipment disagreements can be avoided by each partner supplying himself with whatever carry-on technology suits him (12v refrigerated coolers, flexible solar panels, hand-held GPS, etc.)Sounds like a business, doesn't it? That's exactly the mindset that needs to be adopted if a falling out among friends and a possile financial loss because an unnecessarily steep depreciation occured is to be avoided. It might be attractive to think that friends can just operate a boat together on a handshake, but experience proves that formalizing a plan makes everyone happier in the long run. The anal-retentive will be satisfied, and the happy-go-lucky parter will appreciate the responsibility that others have shouldered on his behalf.Or, each couple could just bareboat charter separately and show each other the photos over wine and cheese later…
