4.Consider the resale value, but in moderation. If you love this boat and plan to keep her for a while, doing a refit to maximize your enjoyment is a fine idea. But if you think that adding a $100,000 refit to a boat worth $200,000 is going to make her worth $300,000, you need a lesson in Reality Math. It would be like adding a $10,000 paint job to an old Ford Pinto. It just makes it a shiny old Ford Pinto, not a Ferrari. Do it because you love the boat, not because you plan to flip it.
