Welcome to Ugly John's Custom Boats!

Known far and wide as one of America's largest dealers, Ugly John's Custom Boats serves mid-America and beyond from 5 locations. As the nation's largest Cruisers Yacht dealership for 3 consecutive years, we consistently have a larger selection of boats in inventory and ready for immediate delivery than any other dealer anywhere. In addition to Carver Yachts, we are also a dealer for Prestige and Jeanneau Yachts, Monterey runabouts, deck boats, and Nautique Tow Boats.

Because we are such a large new boat dealer, we also have a wider selection of pre-owned values than any other dealer. Our "Slightly Used" boat inventory is updated frequently on this website. Of course, if you are looking for a particular boat and you don't see it here, chances are good that a sales professional at any of our 5 locations can help you find it!

If there is a niche for you in the pleasure boating world, we can fill your needs at Ugly John's Custom Boats. If we don't have or can't find the boat you're looking for...nobody can!

2009 US$ 498,790

Navigator Yachts hull shape was designed with one thing in mind: make the best use of a minimum amount of fuel and horsepower, and retain the maximum amount of boat speed and efficiency. In doing so, Navigator created a wide hull shape that is stable at rest and at displacement speed, while achieving 30% less wetted running surface when on a plane. The result is a hull with much less drag, a significantly smoother ride, and far better fuel economy.


This low hour 2009 5800 is the one and only 58 ever produced (to our knowledge) with Volvo 575's, a centerline master and the extended seating section on the bridge.  Navigator Yachts were built for rough water use and designed with comfort, quality and efficency as the backbone of their brand.  You will have a difficult time finding a yacht with like features and space, built with this workmanship, for a price even remotely close to what you see now.

This yacht was sold new by Ugly Johns and has spent it's entire life under covered docks on Grand Lake, in Oklahoma.  All service has been done by our Volvo Certified team.  With under 100 hours on the motors and 240 on the 19kw Kohler Diesel generator, the boat has clearly had a very easy life.  It is well equipped and ready for use, wherever you may choose to take her.  We can arrange shipping and delivery anywhere within the 48 states.
