The more you defer maintenance
, the costlier it becomes. What you want to do is keep the boat's condition up to the point where you only have to do "maintenance," rather than "restoration."
We've all seen the ads where a boat is being sold for $20,000 after having gone through $200,000 in "restoration and upgrades" in the past decade. Ouch.
I had a buddy once who installed an $4,000 engine
into a $2,000 boat, and was shocked to discover that he could only sell the boat for $2,000 thereafter. The moral here is that when somebody tells you to expect to pay 10% of the boat's value per year in maintenance
, he's for certain not talking about an older boat.
