The world’s largest sportfishing yacht, the six-deck, 171-foot all-aluminum Project 406 from Royal Huisman and Vripack yacht design, is finally here.

It’s been three years since Yachting first reported on Project 406’s development. Details and interior views of the build are still being kept quiet, but what we do know is that Royal Huisman says the supersize sportfishing yacht is headed to its final staging area and preparing to launch in Amsterdam soon.

In a press release the shipyard stated, “Project 406 is designed for an experienced owner who is passionate about fishing. She is a unique vessel in so many respects. Vripack Yacht Design is responsible for the exterior and interior design and naval architecture of this highly prestigious project. Her design is extremely distinctive, with a long bow and high bulwarks sweeping through a clear sheer to a low and uncluttered cockpit aft.”

“The high tower offers outstanding views with a downward angle on the water for specialized fishing. Apart from its practical function, the tower also offers a superb viewing platform for guests, who can follow all the action below. Project 406 effortlessly blends the ultimate sports fishing experience with genuine superyacht scale, comfort and refinement.”

Royal Huisman says a team of more that 350 craftspeople worked on the build over the last three years.

At its 171-foot length overall, Project 406 now tops several other giant custom sport-fishers such as the 144-foot Trinity Bad Company, 130-foot McMullen & Wing Mea Culpa and the 129-foot Yachting Developments Lanakai, by a significant margin.

When the build was first announced in 2021, Royal Huisman CEO Jan Timmerman called Project 406 “the world’s first true sport-fish superyacht,” while Vripack co-creative director Bart M. Bouwhuis says it’s “a sport-fisher on steroids.”

Seeing the results. We’d agree.
