The most expensive boat is the Grady-White, at $87,725 with a single 250-hp Yamaha HPDI. Why so much? There are a lot of standards, and most are a grade above the rest. Livewell and washdown pumps are dedicated and 1,100 gph instead of the more common 800 gph, or shared, pumps. The standard head is a fixed electric, not a portable. Plus you get items the others leave out, such as windshield wipers, a refrigerator, locking electronics box, vertically and horizontally adjustable seats, and windlass prewiring. Still, even with all these advantages, it's a lot of money.
