Kristy Hinze, Jim Clark Marry (SLIDESHOW)

Swimsuit model Kristy Hinze became the fourth Mrs. Jim Clark on Monday.

The 29-year-old Sports Illustrated cover model married the 65-year-old Clark, who founded Netscape.

The beach ceremony was part of a four-day affair that took place on Clark's $100 million yacht, Virgin founder Sir Richard Branson's private Necker Island and Virgin Gorda Island.

Wearing an Oscar de la Renta dress and attended by seven bridesmaids, Hinze told the Brisbane Times: "It is a very relaxed-feel wedding and Jim and I are both calm and just enjoying each other - and being with our close family and friends."
