From her cold-molded fir and Okume bones to fiberglass skin coated in glossy Alexseal Cloud White, the 77’ Jarrett Bay stays true to its custom Carolina heritage, yet represents the next evolution in sportfish performance and functionality. Thanks to prop tunnels, the 77’s shaft angle is lower, yielding increased speed and efficiency - and a noteworthy draft of less than six feet. The high-speed stainless rudders and struts and a bottom with no through-hull protrusions or fairings result in an incredibly fast and sleek running surface.

Jarrett Bay 77

Under the hood, you’ll find twin 16V-2000 MTUs rated at 2,600hp. Carrying 3,200 gallons of fuel, the 77 hits a top speed of 41 kts and cruising speed of 35 kts. With nearly 60 custom builds to date, Jarrett Bay designs their hulls, first and foremost, with performance in mind. Jarrett Bay’s proven modified-vee hull design uses steadfastly seaworthy, lightweight materials allowing the 77 to be faster than other similarly sized boats with equal or more horsepower, and significantly superior fuel economy than custom and production boats in her class.

Interior Layout

The 77’s interior mirrors her sleek exterior with high-gloss cherry veneers throughout its five stateroom, six head layout. Flawless joinery covers her TriCel composite keeping the weight to speed ratio at top performance levels without sacrificing durability in the roughest seas.

Cockpit Layout

The 77’s sweeping mezzanine overhang gives way to a massive 255-sq. ft. cockpit, complete with two pressurized live-wells with capacities up to 125 gallons.
