Nonsense. A yacht must be kept up and looking good, simply because a shining, waxed hull will let damaging, encrusted salt be rinsed away. A clean boat will show cracking, blistering, or other flaws more readily, allowing the owner to stay on top of problems and intiate repairs before they become structural or catastrophic. Chalky, faded, or stained exteriors indicate larger problems to those who will place a value on your boat-brokers, surveyors, and, ultimately, buyers. And even if you're not selling now, you'll be glad you set up a scheduled maintenance plan for the topsides of your boat. The problems associated with staying on top of your topsides can be held off with the right regimen of preventive maintenance.
