Ocean Alexander 100 Motoryacht

oa_100

Designed by Evan K. Marshall with charter in mind, the OA 100 is the natural progression from the highly acclaimed OA 90. A “boater’s boat” in every sense, her configuration and performance is traditional Ocean Alexander, while her impressive volume, style, and enhancements made for charter are distinctly her own.

Accommodations

Two things immediately stand out when entering the boat from the aft deck: One, the living space is scaled upward, projecting the feeling of being on a much larger vessel; and two, great emphasis has been placed on natural light with massive side windows. The vibe is upscale contemporary across a lengthy saloon that makes good use of the boat’s 23-foot beam, and amid the fashionable combination of light and dark fabrics and structural elements, attention is drawn to the handsome custom-fit cabinetry adorning the formal dining area. Forward to port is a plush gourmet-level galley perfect for personal or charter use, complete with marble countertops, brand-name appliances from Thermador, Fisher & Paykel, Viking, Whirlpool, and Sub-Zero, and a full-size pantry. The characteristic Ocean Alexander open-galley arrangement is a lovely part of the boat to settle into, with tall bar chairs that belly up to a wide pass-through. Beyond is a warm, inviting lounge area with rich woods and a hefty L-shaped settee perfect for casual dining or enjoying a cup of coffee underway.

Each of the four staterooms has its own en suite head with marble countertops and soles. The full-beam master is well-insulated to sound and is nothing short of exquisite—with handcrafted nightstands, oversized windows casting abundant natural light, a love seat, a large walk-in closet and hanging locker, and the popular his-and-hers head arrangement separated by a shower.

Construction

Worth noting is that Ocean Alexander also offers a skylounge version of the 100, which trades the lower helm for a custom-made desk and essentially gives her owners a second saloon up top with what I would call a “gentlemen’s bar” and a stylish lounge with panoramic views behind the triple-chair helm station.

The builder employed high-density structural foam coring above the waterline and throughout the stringer system, with cross-knit directional carbon fiber in high-stress areas, and the resultant added strength is felt underway. Even a decent chop amounts to no big deal for the 100, a testament to vinylester-resin-infused fiberglass lamination and high-density structural foam in the hull and in longitudinal stringers and crossmembers.

The engine room is an impressive expanse of glitzy stainless steel. Accessibility around the pair of 1,925-horsepower Caterpillar C32 ACERTs seems to have been made a priority, complete with 7-foot overheads and generous workspaces. Plumbing, hydraulics, and electrical wiring are all color-coded and clearly labeled for user-friendliness.

Performance

Underway, the 100 comfortably holds her own—even in a decent chop—with every bit of the class and refinement she emanates from the docks. She’s user-friendly whether cruising or docking. Rudders are quick to respond, and the hull shape yields a smooth entry with no slapping. You get the feeling there’s a lot of boat underneath you—and there is—but never at the cost of losing control, even on an ill-tempered weather day at sea. Typical of Ocean Alexander, the 100 is conservative at the low end in terms of fuel efficiency. The burn of course picks up a bit on the higher end, but the numbers are still fair thanks to her slippery semi-displacement hull form.

“You’ve really got two sweet spots [on this boat],” noted our sea-trial skipper, whose favorite models in the range are the 90 and the 100. “In displacement mode there’s one around 1,100 rpm that gives you 10 to 12 knots burning a total of just 24 gallons per hour. With 4,000 gallons of fuel underneath, that gets you all the way up the east coast in time for summer cruising season. Then, in semi-displacement mode, there’s another sweet spot between 1800 and 2100 rpm, somewhere around 20 knots, burning 140 gallons an hour.”
