Founding of Kentuckiana Yacht Sales In 1960

Leon Shaw begins his career in the boating industry by forming Kentuckiana Yacht Sales with partner & high school friend, Bill Brummett. Their first location was at the corner of Spring St. & Riverside Dr. in downtown Jeffersonville.

Interestingly, Kentuckiana Yacht Sales was the first boat dealer in the Louisville area to sell fiberglass boats,

Founding of Gibson Houseboats

Building on the success of the booming fiberglass houseboat industry, Leon Shaw & partner Bill Brummett seized the opportunity to expand into fiberglass boat manufacturing.

In 1967 the tragic loss of Drift-R-Cruz founder and fiberglass pioneer Bill Willcutts resulted in several of his key boat builders, including Carl Gibson, to search for a new company to produce houseboats. Having known Shaw & Brummett from their success in houseboat sales, Carl Gibson pursued them to open a factory in Goodlettsville, Tennessee.

By 1968 production was underway and the first model introduced, which was a 30' Gibson with a base price of $8,995.

Gibson Houseboats would soon become one of the top selling houseboats on the market.

Kentuckiana Yacht Sales Moves to 700 E. Market St.

By this time, Shaw & Brummett had positioned KYS as a top-selling dealer for Nauti-Line, Owens Cruisers, Whitcraft & SeaGoing Houseboats, as well as the factory sales center for Gibson Houseboats.

The new location provided much needed space to operate as KYS was now a major parts & service center, recognized by Chrysler as a national "Top 10" engine dealer.

Now two years in to production, Gibson Houseboats are quickly becoming one of the most popular houseboats on the market.

Leon Shaw Begins Importing Trawlers As Distributor For Chung Hwa

Recognizing the increasing demand in aft cabin motor yachts & early success of trawlers coming from Asia, Mr. Shaw ventured into this emerging market. These new imports were soon competing against the used motor yachts on the market.

This was the origin of Leon’s pursuit for a quality boatyard with forward thinking individuals to partner with and develop what would later become Jefferson Yachts.

Jefferson Yachts Founded by Leon Shaw

Mr. Shaw forms a partnership with the Liu family of Hershine Marine. Mr. T.C. Liu originally came from the fishing industry where he owned & operated a fleet of fishing vessels. In 1977, Mr. Liu began building yachts with similarities of a trawler, but with more progressive hull shape & deck styling unlike his local competition.

Mr. Shaw & Mr. Liu became both great partners & friends, as they shared many of the same values and indeed were both forward thinking in this new venture. They immediately began working to develop a line of new yachts to compete in the US market.

Beginning of Marlago Boats

With the industry on the rise from the downturn of the early 90's, Jefferson was pursuing new ventures to complement their newly developed model line-up. We began to see a trend emerging from owners of large sport fishing yachts downsizing to center consoles that would accommodate their fishing crew & gear without sacrificing offshore capability, and save time and money with less maintenance.

The large, open deck design of the Marlago FS35 fit this niche perfectly as it was built to run offshore with a crew of 6-8 with ease. The key advantages of the Marlago include:

  • Our 24° Deep-V Hull Design Features a Stepped Transom w/Modified Pad Keel Creates Fast, Efficient Speeds & Exceptional Ride.
  • Lightweight Design Provides Quicker Holeshot & Efficient Cruising.
  • Greater Range & Easily Driven Hull with Less Fuel Consumption.
  • Easily Handled on Smaller Lifts.
  • Much Easier to Transport.
  • Marlago was one of the 1st manufactures to begin building offshore center consoles over 30'.
