Since I've been working on the VolksCruiser project I've noticed a certain niche market in used boats. The upshot is that someone buys a dirt cheap boat that is not selling for pennies on the dollar and then cleans it up (as in just throwing away junk and some liberal application of soap and water) then resells it for a chunk of change more and then simply repeats the process with another boat.
What a great business model! There's obviously no shortage of old boats that need to be cleaned and de-cluttered...
While cleaning up a boat is often not a job not for the faint of heart or squeamish it's not really that hard and as a clean uncluttered boat is worth more than a mold farm and a whole lot easier to sell it.
So, if you happen to notice that cheap funky awful looking CAL or Pearson you were thinking about buying magically reappears looking tidier and sprightly for a few thousand dollars more, you might want to keep in mind that you could have bought it for a lot less and a couple of days cleaning.
For those folks who have a boat for sale... I suspect there's a lesson to be learned here as well.
