Our Brokers
Bill’s knowledge of boats and the sea began at an early age. Growing up on Long Island Sound, his boating days began before he learned to walk. By age 14 he was working as a mate for some of the best captains of the time. His fishing career ultimately led him to Central and South America, Australia, Nova Scotia and many ports in between.
In 1986 the opportunity to become a partner in a Bertram dealership in South Texas sounded too good to pass up. Today, with 29 years of experience in the boat business behind him, Bill is able to provide his clients with the product knowledge and firsthand experience that have come to be his trademark.
The lack of high pressure selling and the ability to answer questions honestly and thoroughly have provided Bill’s clients with a comfort level that has kept them coming back to him for many years.
Specializing in large custom sportfisherman and motoryachts, Bill is always eager to help and guide his clients toward selecting the right boat. Be it new construction or brokerage, there is no substitute for firsthand knowledge and experience.
Bill’s latest endeavor is the founding of Michael Rybovich & Sons Yacht Sales, with Michael himself, at the new yard in Palm Beach Gardens.
After leaving the Navy in 1964, Mike went to work building boats. Also, through the years, he became a 100-ton licensed Captain, running boats through the Bahamas, the Caribbean, and up to California. He later left running boats to work for several boat builders and yacht brokerage firms.
In the 1970s Mike managed Bertram Yacht yard in Miami, for Dick Bertram, and later his family boat yard in Stuart, FL.
In 1980 Mike joined Rybovich & Sons Boat Works in West Palm Beach and remained there, working in many capacities including President, through 1991.
Mike has previously served as President of the Marine Industries Association in Martin County, Director of Marine Industries Association of South Florida and President of the Stuart Sailfish Club.
Mike’s job these days is running Gamefisherman Boats in Stuart, FL and now multitasking as a broker with Michael Rybovich & Sons Yacht Sales. Mike has actually owned two Rybovich boats himself. Mike says “It’s great to again be associated with the Rybovich Family!”
