As a boat buyer, you might be asked, paraphrasing the server at your favorite diner inquiring about coffee sweetener, “One hull or two?”

Invincible’s patented ­monohull has one of the lowest drag coefficients in its class. On its Open Fisherman and Center Cabin boats, 33 to 42 feet long, an air-fed tunnel produces higher speeds with lower power, plus a more stable ride — all while maintaining supple maneuverability. Designed by naval architect Michael Peters, it’s a fast hull in which passengers stay dry and comfortable, even in rough seas.

Take the best from the Invincible monohull and double it, and you have the firm’s patent-pending catamaran hull, with that design’s additional stability.

Morelli & Melvin, America’s Cup sailing-yacht creators, created the hybrid semi-asymmetric design. The result? Monohull-like maneuverability with comfortable handling in even quartering and following seas.

A pod between Invincible cat hulls splits water to soften the ride, and even with their ­additional size, the cat fuel economy is comparable to a monohull.

Invincible 40 Cat
A big, seaworthy boat that seems to yearn for single-day, as well as multiday, adventures to far-off fishing hot spots, the 40 Cat was Invincible's first in that format, creating what it called "the most advanced fishing catamaran on the market."

Seakeeping ability was its original and overriding goal, especially making high-speed turns without drastic throttle reduction. It accomplished that through its game-changing asymmetrical sponsons. The double-stepped hulls lift onto plane quickly, reaching 55 mph in 10 seconds and tops out at over 70 mph when rigged with 350 Verados.

A huge aft deck, with ­26-inch-high gunwales and nearly 11½ feet interior width, sets the stage for efficiently fighting multiple fish.

Three livewells — twins of 55 gallons each at transom and a 72-gallon well beneath the cockpit sole — more than meet the two-livewell (93 percent) and ­big-bait-capacity (­61 ­percent) minimums of ­survey respondents.

Coaming pads ring the interior to cushion anglers’ legs amid fights. When the battle’s done, the 40 Cat houses the catch in two massive fish boxes below the aft deck, with another pair forward.

Rod-holder and storage options let you create your own fishing boat. Options also ­include a hardtop, ­folding tower/dual station or ­crow’s-nest, three-across helm seat ­configurations, an aft-facing bench that adds seating for three more, an outrigger, coffin box and more.
