If this is just a rant, rant away.
However, if this is really this big of a set back, maybe you do need to reevaluate. Boats are certainly expensive.
That said, the most expensive year is often the first one. I too bought a boat this year and I had more in it than the purchase price in less than 4 months. With luck, I won't have to put so much into it in subsequent years.
Like I said we owned this boat only a couple of months, and none of this was on the survey. I expected $$$ for upgrades as we went along, not $$$$$$$ from bad luck.
The way I see it, you can look at this two ways. First, expect bad luck (and good luck, too). Alternatively, if it aint broke, don't use it.
Personally, I would stick it out a lot longer than three months. You're going to have a learning curve, but there are some fine rewards to owning a nice boat.
