Well established in the center console fish-boat market, Invincible has also dug deep into the catamaran genre with 35-, 37- and 40-footers. Continuing to push the envelope, Invincible’s all-new 46 Cat perhaps ranks as the coup de gras. A large, open, spacious, well-appointed boat, the 46 remains focused on fishing features and performance.

Balancing the trade-offs inherent within the cat design, the folks at Invincible have blended the need for storage, fishing features and comfort with equal measure. Cats offer a great deal of space all through the boat, and this 46 is no exception with plenty of room to walk around the console and huge areas in the cockpit and forward deck.

Live baiters need not worry, as the transom hosts dual 60-gallon livewells, four tuna tubes, and a 72-gallon in-deck well in each hull. My test boat had a total of 75 rod holders, a molded dive door on the port side and four in-deck fish boxes, totaling 1,334 gallons of capacity.


The console houses a head, access to the main breaker panel, battery switches and electronics connections. The well laid-out dash features room for two 24-inch Garmin screens. The center-mount helm, binnacle, joystick controls and all control switches for systems reside under a beveled Plexiglas cover for easy access and visibility.

Dual-row helm seating offers comfortable three-across seats with armrests. Aft of the second row lies a mezzanine bench for three with a large molded cooler with chill plates beneath.

The grid stringer system, vacuum-infused hull, deck and parts married to myriad quality components make for a strong, quality-oriented boat.

Performance and speed have become a hallmark of the Invincible brand, and the 46 follows that path. With quad 450 hp Mercury Racing outboards, the 46 cruised along at 4,000 rpm, making 50 mph while burning 62.5 gph for 0.8 mpg. Wide open, the 46 hit a blistering 78 mph in Florida’s Biscayne Bay, clearly keeping it in line with the rest of the Invincible high-performance models.
