There was a time not so long ago that a 50- or 60-foot convertible would have been the biggest sportfish in the marina. But times have changed, and in the place of those trusty battlewagons of yore has emerged a class of fishing boats that are their own subsect of the superyacht category.

Whether they’re built by semi-production giants, small-town custom builders, or as one-off projects by superyacht yards, these boats are designed to do one thing: catch monster fish. While most have the conventional shape—a long forefoot, tuna tower for sighting schools of fish or birds that are feeding on them, and the fighting chair in the cockpit—others are deviating into new territory.

Vanquish has a new 80-footer, with a plumb bow and cruiser-like profile, that has been modified as a serious sportfishing machine, while Royal Huisman is taking the concept into extreme superyacht territory with its 171-footer that’s a six-deck superyacht shaped like a huge convertible. This category is morphing somewhat with these new designs, but for the most part, the changes are more about luxurious interiors and better technology in the engine rooms.

Have a look at our list of the biggest and baddest luxury sportfishermen, plus one pint-sized classic thrown in for balance.
