French Tax boat
I believe this probably refers to the following: Up until a few years ago, there was some sort of French tax loophole that allowed the French to deduct their charterboat expenses twice. Because of this generous tax loophole, there were alot of charterboats in the caribbean owned by French citizens who made their money of the tax benefit and didn''t really mind in nobody chartered the boat.
Anyway, the loophole was closed a few years ago, which led to a lot of boats being put up for sale. I bought one of these boats out of the Sun Yacht Charter fleet. Little wear, nice price, motivated seller.
