Great discussion. Everyone's circumstances are different but I can honestly say I am glad we didn't think about the ongoing cost too much (actually we did, but we underestimated). Cutwater28GG raised a good point
That the value of thevpure enjoyment of being on the boat, whether travelling of not, is impossible to calculate. And, we have saved thousands annually on summer airfare and hotels since we bought her.
This year we have a mooring for the first time. We lost the lottery at our favorite (municipal) dock and unfortunately they run it so late its hard to find open space elsewhere if you lose your space. Anyway, planning for next year and welcoming advice. The mooring has worked out fine and saved us a bundle even after buying a dinghy, thus the relevance to this thread. We miss the hose and electricity, but we figure the savings will also pay for some extra detailing.
We are in salt water and I worry about not hosing her down consistently. Will welcome any thoughts on seasonal moorings vs dock slip pros and cons.
