No one in the history of the IGFA has achieved more Billfish Royal Slams than Mark Davis, who accomplished the incredible feat of catching all of the world’s billfish species eleven times. Over the past four decades, Davis has been pursuing the world’s premier big game species in iconic destinations including the Great Barrier Reef for black marlin; New Zealand for swordfish; Nova Scotia for giant bluefin tuna; and Madeira and Kona for big blue marlin.

In addition to his unprecedented number of billfish slams, Davis has also released blue marlin and bluefin tuna estimated at over 1,000-pounds, and has landed swordfish over 600 pounds.

Twelve years ago, Davis purchased the Sea Genie II-- a beautiful 39-foot Rybovich based out of Kona, Hawaii. Under the guidance and expertise of renowned Captain Gene Vanderhoek – the only captain ever to record four grander Pacific blue marlin---- Davis transformed the Sea Genie II operation into the top tag-and-release blue marlin and spearfish boat in the Pacific before selling the business in 2019.  Amid all of his achievements and contributions to big game angling, Davis' most valued accomplishments have been introducing his family to the joys of big game fishing, and leading each of them to accomplish their own Billfish Royal Slams.
