Boat of the Week: This 171-Foot Super-Luxe Sportfishing Yacht Is the Largest in the World

The epic vessel is a super fast "battlewagon" designed to chase marlin, swordfish and sailfish. It's also decidedly lavish.

To hook the world’s biggest fighting fish, in the words of Chief Brody in the classic 1975 movie Jaws, “You’re going to need a bigger boat.”

Privately owned fishing boats won’t come any bigger than this astonishing 171-foot super-luxury sportfisherman, set to claim the title of “World’s Largest Sportfish Superyacht.”

Designed by Dutch naval architects Vripack, and soon to start construction at the Royal Huisman yard in the Netherlands, Project 406 as it’s currently codenamed, will be a fast “battlewagon,” designed to chase marlin, swordfish and sailfish to the ends of the earth. “Project 406 is a sportfishing machine on steroids,” Vripack co-creative director Bart M. Bouwhuis told Robb Report. “It has the proportions of a typical American sportfishing yacht, with a long, flaring bow and open foredeck, and raked-back superstructure. It’s just bigger in every way.”

Bouwhuis is quick to point out “this is a sportfisher first, and superyacht second. While she will have the luxury of a true superyacht, she’ll set a new benchmark in the world of big-game fishing boats.”

Renderings from Vripack show a towering, six-deck fishing machine with the sleek proportions of smaller battlewagons from American builders like Viking, Hatteras and Jarrett Bay.

To shave weight, the hull and superstructure will be made of Alustar aluminum, a super-strong, high-tensile alloy. Bouwhuis won’t reveal the yacht’s power, though the word “huge” comes out in the conversation. “You can’t fool nature if you want a 171-foot boat to go this fast,” he says. “It will have significant horsepower.”

The yacht has been commissioned by an experienced owner who is passionate about big-game fishing. “There are yachts out there that label themselves ‘sportfishermen,’ but they tend to be big motoryachts with a small fishing cockpit on back. Project 406 stays true to the traditional proportions.”

That means an oversized stern cockpit that’s low to the water, with a classic varnished-wood fighting chair takes center stage. Each of the decks above it will face the stern to give guests a front-row view of the sportfishing action below. For thrill-seekers, the very top deck, high above the flybridge hardtop, will provide stunning 360-degree views of the water. Perfect for spotting leaping marlin.

When the fish aren’t biting, Project 406 will offer guests plenty of places to kick back and relax. On the bow is an expansive, sunken sun-lounging area with oversize pads and sofas. The yacht’s fourth-level sky lounge will serve as an extraordinary “theater” for watching big-game fish leap out of the water. At night, it will have the relaxed ambience and stunning views of a boutique hotel penthouse.

“It has been a steep learning curve for the whole Vripack team, discovering what makes a great sportfishing boat and understanding what kind of features are needed—from the rods, to the baitwells, the icemakers and fish boxes,” says Bouwhuis. “But it has definitely been an exciting challenge.”

It’s hard to understand the unbridled passion for fishing, especially when discussing the world’s largest sportfishing boat.  But actor Lee Marvin summed up the feeling nicely: “I only make movies to finance my fishing.”
