By introducing the 45 Divergence, Ocean Alexander whose previous smallest vessel was a 70' yacht, delivers an uncharacteristic outboard-powered, open boat they describe as a “day yacht.” As would be expected from Ocean Alexander, it inherits many yacht-like qualities.

Captain’s Report by Capt. Mark Kellum
Ocean Alexander classifies the 45 Divergence as a “Day Yacht” whose potential customers are Ocean Alexander owners who want to stay in the family and want a day boat or tender for their big yacht. Ocean Alexander also designed and manufactured the 45 Divergence to attract those that appreciate the quality build and luxury features of an Ocean Alexander. Their unique approach to a center console sportboat sets the 45 Divergence apart from the already crowded class.
- Quad 350-Horsepower Outboards. 45 Divergence is the first outboard powered boat for Ocean Alexander.
- Summer Kitchen. The summer kitchen is mounted abaft of the helm seat base and features a large prep area, an electric grill, a two-burner cooktop and a sink with a cover that can be reversed and used as a serving tray.
- Port and Starboard Wing Decks. The bulwarks on the port and starboard sides of the aft cockpit hydraulically lower to create wing decks on both sides.
- Flexible Aft Cockpit Seating Options. A forward-facing bench seat folds out of the transom bulwark. The bench seating forward has a flip-flop back rest. A table rises out of the deck between the forward-facing transom seating and the forward aft cockpit bench seating to form an al fresco dinette area.
- Pop-Up Flat-Panel Television in the Aft Cockpit. The aft facing 50” (127 cm) flat-panel television can be viewed from both aft cockpit bench seats with the forward bench backrest in the forward-facing position.
- Flexible Forward Seating. The Ocean Alexander 45 Divergence has triple wide lounge seating built into the forward cabin trunk. The bow seating surrounds a solid wood table that lowers to create a sun pad with fitted upholstered filler-cushions.
- Cabin. The cabin offers 6’7” (2.01 m) of headroom with a small galley with counter, sink, and microwave. The U-shaped dinette can be converted to a double berth.
- Full Head. The head in the Ocean Alexander 45 Divergence features a vessel sink mounted on a vanity and there is a full walk-in shower.
The Ocean Alexander 45 Divergence has a length overall of 47’5” (14.45 m), a beam of 13’9” (4.19 m) and a draft of 37.5” (95 cm). With a dry weight of 28,900 (13,109 kg), 75-percent of fuel, 87-percent water, four people onboard, the test Ocean Alexander 45 Divergence has an estimated weight of 33,118 lbs. (15,022 kg).
Top Speed. With quad 350-hp Mercury Verados turning 17 pitch propellers run up to 6200 rpm, the Ocean Alexander 45 Divergence tested reached a top speed of 46.5 mph (74.83 kph).
Best Cruise. At 5000 rpm and 38.7 mph (62.28 kph), the Ocean Alexander 45 Divergence achieved a 69.7 gph (263. 8 lph) fuel burn that translated to 0.6 mpg (0.97 kpg) and a range of 303 statute miles (487.6 km). When the Ocean Alexander 45 Divergence was placed in “no-wake” mode, 1000 rpm equates to 1.3 mpg (2.09 km) and a range of 702 statute miles (1,130 km), while still reserving a 10-percent of the Ocean Alexander 45 Divergence’s 607-gallon (2,298 L) total fuel capacity.
Because the Ocean Alexander 45 Divergence is built to the same tolerances as the company’s larger yachts, the 45 Divergence is a heavy boat, so maneuvers don’t happen fast, which in turn adds to the comfort level for those onboard.
With light chop when running on the test day the Ocean Alexander 45 Divergence handled nicely with only a slight hull slap at top speeds. At cruise speeds, the Ocean Alexander 45 Divergence cut through the waves sending spray low and wide for a dry ride. Slow the Ocean Alexander 45 Divergence even more and now she tends to oppose the waves and break through rather than slice through, so owners should not be hesitant to let the 45 Divergence run. When accelerating from 0 mph, there’s a significant bow rise before she comes on plane and settles in. It is important to remember that on the Ocean Alexander 45 Divergence nothing happens fast. She demonstrated a natural running attitude that is about 8-degrees bow high. Pushed to the pins, the test Ocean Alexander 45 Divergence reached planing speed in 6.8 seconds, accelerate to 20 mph (32.2 kph) in 10.4, and continue through 30 (48.28 kph) in 19.3 seconds.
Freeboard. The freeboard at the swim platform measured 16” (40.64 cm), increasing to 48” (121.92 cm) at midships, and 66” (167.64 cm) at the bow.
The Ocean Alexander 45 Divergence can be boarded via a step outboard of the outboards splash well. A walkway runs across forward of the outboards. Transitioning forward is through transom walkthroughs on both sides.
The aft cockpit on the Ocean Alexander 45 Divergence is the central entertainment area. It features flexible seating, in-deck storage, a summer kitchen and a pop-up 50” (127.0 cm) flat panel television. On both port and starboard sides are boarding doors built into the wing deck portion of the bulwarks. The aft cockpit depth is 32” (81.26 cm).
Aft Cockpit Overhead Protection. Protection overhead in the aft cockpit includes a 7’5” (2.26 m) hardtop that extends to just over the forward bench seating. It has LED lighting and LED spreader lights. An electrically activated extendable awning is 9’6” (2.90 m) that carries back to the aft transom fold out bench seating.
Moving forward to the side decks the bulwarks are 39” (99.06 cm) above the deck. There are two 8” (20.32 cm) steps, one at midships and the second ahead of the helm deck. At the helm the side decks are 22” (55.88 cm) wide.
Transitioning to the highly social forward seating area, the bulwark comes up to 30” (76.20 cm). Ocean Alexander added a grab rail to the bulwark that rises to 34” (86.36 cm) above the deck. There is a triple-wide lounge seating ahead of the windshield and wraparound bench seating in the bow.
The large helm on the Ocean Alexander 45 Divergence is fully featured. Visibility through the 81” (205.74 cm) wide by 53” (134.62 cm) high windshield is uninterrupted. The windshield has a 21” (53.34 cm) brow just above to knock down glare. The helm continues the carbon fiber accent theme.
Digital Switching Systems. Digital switching systems eliminate mechanical switches, contacts, fuses, and bus-bars, and wiring harnesses with separate wires for each and every switch and replaces them with an electrical flow of current distributed through a NMEA2000 “backbone” cable. The interface can be displayed in a number of ways, on the Ocean Alexander 45 Divergence it is through the dedicated Octoplex touch-screen display.
Below decks is the cabin space. Access is through a door to port of the helm console. Inside the overhead height is 6’7” (2.01 m) above the wide-planked hardwood deck. The cabin is replete with a small galley, a dinette that converts to a double berth and a full head.
The mechanical space on the Ocean Alexander is below the aft cockpit. It is accessed through a hatch at the base of the aft cockpit table. Egress throughout the mechanical space is tight but well-organized with efficient use of space.

Fishing options with 40-gallon live baitwell in transom and other fishing features

The Ocean Alexander 45 Divergence is a dramatic departure from Ocean Alexander’s traditional 70 to 150-foot plus yachts. The model represents Ocean Alexander’s attempt to expand on the day boating trend making the 45 Divergence with yacht quality fit and finish and take day boating to a new level. The Ocean Alexander 45 Divergence is loaded with standout features in an already crowded class of large outboard center console boats and tenders.
The 45 Divergence is not the type of boat that you jump into and blast off expecting to be the first one to the fishing spot or island destination. She’s more sedate and focused on comfort. While the test Ocean Alexander 45 Divergence was rigged as an entertainment and dive platform, there is another version that is offered as a fishing model, and it will include the usual amenities of livewell, freezer plates in the in-deck fishboxes, more rod holders…. etc. Either way, there’s no denying that Ocean Alexander has redefined what a day boat can be, and how far we can take entertaining in one platform. Ocean Alexander deeming the 45 Divergence as a “day yacht” seems to be the classification.
