Brief Summary

Designers of the Ocean Alexander 78 Motoryacht use aluminum beams in many areas for structural rigidity, allowing for expansive open space in the yacht's interior. Open flybridge or skylounge versions are available. A foyer acts as the hub between three staterooms below decks, the VIP at the bow, the master amidships, and the media room or guest statetoom to port. Each cabin comes with HD screens, rich wood closet space, and en suite heads (the master with a his-and-hers). She's equipped with two Caterpillar C32 ACERT 1622-hp engines and comes with two Kohler 32 kW generators onboard as well.

    Captain's Report

    by Captain Chris Reid

    Ocean Alexander 78 Motoryacht running shot
    The Ocean Alexander 78 Motoryacht has a 20’1'' (6.12 m) beam, draws between 5’4” and 5’11” (1.63 m to 1.80 m) depending on the load and has an estimated displacement of 144,000 lbs. (65,317 kg).


    The Ocean Alexander 78 Motoryacht was designed for owner/operators who want to entertain friends and family in tasteful, yet relatively informal surroundings, and who want to be able to strike out for distant islands and not have to worry about the weather. Her three en suite staterooms take advantage of the yacht’s 20’ (6.12 m) beam, as does the main salon. This is a yacht that is small enough to be easily handled by an owner and spouse and that -- along with her rugged construction and quality build -- will be her main attraction. Nevertheless, she also has large crew quarters for two, so if an owner cares to bring along a captain and mate, there are appropriate accommodations -- and ones much larger than those we often see on European-built vessels this size.


    Ocean Alexander has long been known for building boats that were meant to go to sea, as opposed to many, perhaps, more flashy yachts that are designed first of all to be eye candy along the docks of St. Tropez and Cannes. The Ocean Alexander 78 Motoryacht will hold her own when it comes to dock appeal, but will probably be appreciated more by the veteran yachting crowd as opposed to those who are more interested in bling.

    The builder says the Ocean Alexander 78 Motoryacht has a 425-nmile range at 20 knots.

    Tasteful Elegance.

    The folks at Ocean Alexander know their market and they tell us that most of the people who buy their yachts have been boating a long time and know what they want in a vessel of this size. They also know the taste levels of their clients, and again that runs to the refined and understated.

    Manageable Size.

    We happen to think that the 78 Motoryacht is an ideal size for most families. First of all, most marinas in deep-water locations have an outer dock that can handle a boat of this size. One of the unstated drawbacks to larger vessels, say, those of around 100’, is the lack of adequate dock space except in the locales catering to mega yachts. Another advantage is the fact that she is not much more difficult to handle than a 50-footer. In many respects, larger boats are easier to dock and maneuver than small boats because they move more slowly. With the addition of a strong bow thruster, most anyone can put them in a slip with a little practice.


    also must be mindful of taking care of the vessel, and here again, most people we know would rather have a smaller boat to take care of than a larger one. Not only can a couple easily dock a 78’ motoryacht, but when it comes time to wash her down at the end of the day, it can be easily done in an hour or so. And our experience is that kids who would never think of lending a hand at home, love to wash down a boat. It probably has something to do with pride of ownership.

    If Help is Wanted.

    For those who like to have cocktails once the lines are secure, Ocean Alexander has thoughtfully designed comfortable crew quarters for a young mate or two. This can also be a fine place for a nanny, stew, or cook. For those who do not want help, the crew quarters become a fine fourth cabin -- and a very private one at that.

    Ocean Alexander 78 Motoryacht running shot
    The Ocean Alexander 78 Motoryacht has a 20’1” (6.12 m) beam, which sets her apart from most boats in class.

    Major Features

    The Ocean Alexander design team tested the hull at the BC Research Institute in Vancouver. We’re told that the boat was designed to handle up to Sea State V -- 8’ to 13’ (4 to 8 m). These are conditions that most prudent boaters will never encounter, but it is good to know that the yacht was designed for these conditions.

    Beam Pays.

    In addition to her bottom shape and rugged construction, the Ocean Alexander 78 Motoryacht has a 20’1” (6.12 m), which is somewhat unusual for motoryachts of this size. When we compared the Ocean Alexander 78 Motoryacht with other famous brand names in this size range, we found only one, which was wider, and, virtually, all of the others were 18’ to 19’ (5.48 m to 5.79 m). Not only does this pay off in more room inside, but it also reduces roll and makes the boat more sea-kindly. And, for a boat of the dame displacement, a boat with a greater beam will draw less water.

    The Build.

    The hull of the 78 Motoryacht is built to internationally-accepted scantlings, and Ocean Alexander has a long track record of building strong boats, ones with huge stringers solid engine beds, and robust bulkheads. In fact, her forward crash bulkhead is 3” thick. The builder uses carbon-fiber in high-stress areas. Aluminum beams are used in decking for rigidity and to save weight. Stainless steel brackets, hardware, and door frames are employed for both strength and attractiveness. All fixtures and equipment installed are world class and come from the same venders that supply the finest custom yards in the world.

    Details Count.

    The smaller touches are excellent, too. For example, the motion-sensor activated, high-quality automatic doors between inner and outer spaces are welcome. The lit aquarium as you board the boat itself is a pleasure to see. Soft leathers, granites, teak surfaces, state room en suites, Indian black marble countertops are lavishly used all over the boat. The boat features numerous large HD screens that can disappear with the push of a button, as well as dedicated DVD players and a truly state-of-the-art sound system all nestled in cabinets and bulkheads.

    Flying Bridge -- A Tale of Two Versions

    Ocean Alexander 78 Motoryacht layout
    Shown here with the “sky lounge” design option, which is fully enclosed, the top deck will see a lot of action. Note the day head, something we rarely see on the flying bridge of this size of vessel. The 78 Motoryacht is also available in an open fly bridge version, see below.
    Ocean Alexander 78 Motoryacht layout
    The open fly bridge design has a large wet bar with stools and grill. Note that this area can be reached from both inside the boat and from the aft deck.

    Inside or Outside?

    There are advantages and disadvantages to both flying bridge options. For those who plan to do mostly day boating and entertaining, the open version will probably be the one selected. By being open, seating can be maximized for spectator functions and cocktail parties. And who doesn’t like the smell of salt air and gentle breeze? For those planing three-or-four-season boating, the sky lounge, enclose pilothouse version will probably be preferable. This version will definitely be more comfortable in windy, rainy, and cool conditions and for night running.

    Ocean Alexander 78 Motoryacht running shot
    The enclosed flying bridge, or sky lounge, adds interior space to the boat without a commensurately large up-charge. The large space on the boat deck can be used for chaise lounge chairs. Note the wet bar and electric grill on the bulkhead for the pilothouse.
    Ocean Alexander 78 Motoryacht bridge
    This bridge is made for an owner/operator seated in the middle and flanked by spouse and family member or guest. The more eyes keeping watch the better. Note the chairs by Stidd and the narrow windshield mullions and her terrific visibility.
    Ocean Alexander 78 Motoryacht helm
    The helm console is flat, just as they are on commercial vessels. Note the burl wood and easy-to-find instruments and controls. We like the four screens but would prefer to see them lower and recessed into the console to improve forward visibility.
    Ocean Alexander 78 Motoryacht dinette
    Behind the helm is a raised dinette that comfortably seats four people. Note the two large windows aft that aid rear visibility from the helm. The door handle at the right is to the day head, something we rarely see on the flying bridge of a 78-footer.

    Upper Helm Station.

    In the Ocean Alexander 78 Motoryacht seen here, the ship’s only helm is located on the flying bridge. However, a lower helm station can be located in the galley area below, if desired. In the version with only the upper helm, space below is maximized for friends and family and living aboard. That is precisely the reason we think that the flying bridge-only helm makes a lot of sense. For those who want a captain, it also permits him/her to pilot the boat without disturbing the guests below.

    Boat Deck.

    In both versions, note that the ship’s tender rests awartships at the rear of the boat deck. This is the ideal place for the tender, both for practical and aesthetic reasons. When the boat is at anchor or at a dock, the tender is usually in the water, which frees up the boat deck for other activities. A 14’ extended hydraulic davit does the lifting and can be handled by one person.The chocks for the tender can be easily removed, making a smooth deck surface for cocktail parties or for chaise lounge chairs for sunning.

    Aft Deck

    Ocean Alexander 78 Motoryacht aft deck
    The aft deck will be one of the most popular places on the boat. Note the wet bar in the background.

    The aft deck is completely covered by the boat deck above and features a versatile dining table with comfortable seating. Some owners may want to rig their aft deck with isinglass to make a three-season “sun room” out of this space to maximize the utility of the boat. We have found that this is a good idea when an otherwise sunny day at sea can be chilly when running.

    Owners in the Mediterranean

    like to moor their motoryachts stern-to and have al fresco dining on the aft deck in the evening. It’s fun to see the passing boat mates as they walk past on the hard. Owners wanting this sort of use of the aft deck we would recommend a slightly different layout than the one seen in the photo above, as well as a differently shaped table. Ocean Alexander will be glad to make these changes as to a great degree the vessel is highly customizable.

    Interior Inspection

    Ocean Alexander 78 Motoryacht layout
    The inside space of the main deck of the Ocean Alexander 78 Motoryacht is nearly equally divided between the salon aft and the country kitchen forward. This style was popularized some 209 years ago in the U.S. on large yachts, and now the European builders are beginning to adapt it. This arrangement fits well into an owner/operator yacht.


    Ocean Alexander 78 Motoryacht salon
    Looking aft in the main salon, we can see the large windows with Roman shades. Note the match-booked treatment of the veneers on the cabinets, the tasteful, modern sconces on the window mullions, and the built-ins that house the electronic equipment and stemware.
    Ocean Alexander 78 Motoryacht bulkhead
    Looking forward we see the sconces flanking the mirror on the forward bulkhead, which makes the space seem even large than it is. Note the day head in the passageway to the galley at left.

    The salon is furnished with a large L-shaped sofa with two facing barrel chairs and a large wood coffee table in the middle. The sofa is custom-made and is not built in, which make the salon more like one’s living room. There is storage under all of the seats and a hide-a-bed can be built into the sofa if desired. The deck is covered in carpet, and, overhead, there is a soffit with lighting. As can be seen in the images above, the 20’ (6.09 m) beam permits lots of space to walk around in the salon.


    Ocean Alexander 78 Motoryacht dining table
    The dining table in the country kitchen is the primary dinning venue on the Ocean Alexander 78 Motoryacht. In this relaxed atmosphere, guests can share their day’s adventures with the chef. In the morning, it becomes a cozy breakfast nook. Clearance is tight between the end table and the table, something that can be easily remedied by re-configuring the end tables. Note the spectacular view forward. Manual or electric blinds can be installed.
    Ocean Alexander 78 Motoryacht kitchen
    Cooking in the 78 Motoryacht’s country kitchen will be anything but drudgery with a view like this. The counter at right is granite, which is specified by the owner.
    Ocean Alexander 78 Motoryacht refrigerator
    We like the stand-up full-size Jenn-Air refrigerator/freezer with French doors -- just make sure they have a latch. Note the book-matched cabinetry and Sapele wood on the bulkheads. The deck in this space is wood, either synthetic for easier maintenance and durability or real wood.
    Ocean Alexander 78 Motoryacht cooktop
    Note the cabinetry space in the upper left side of the image as well to the right. The glass cooktop measures 30” and the electric oven below measures 27”. The trash compactor and all appliances come standard.

    Galley Details.

    With an overall finish of granite and stainless steel, the kitchen is beautiful to look at and use. It actually strikes one as made for land on first impression -- large, fully functional appliances, plenty of cabinet storage space, a double sink. The refrigerator has French doors, and the oven is 27” and top-of-the-line. Keeping in line with the boat’s owner/operator mission, there are labor-saving devices -- garbage disposal in the sink, microwave, and full-scale dishwashing machine -- all elements that make galley chores easier on the water. The 78 Motoryacht offers options in galley design. The one seen here has ample counter space for food prep and plating meals to serve guests on the aft deck or in the country kitchen.

    Lower Helm Available.

    A lower helm is available for those owners with an open flying bridge who are concerned about inclement weather. We might also suggest that isinglass can be installed around the helm in the open flying bridge.

    Lower Deck/Accommodations

    Four-stateroom layout. Here we see bunk beds or a Pullman berth. This space can also be used for storage, a workstation, or laundry room.

    All three of the 78 Motoryacht’s staterooms are large enough to be comfortable enough for long trips. A foyer acts as the hub between the three staterooms -- the VIP guest space under the bow, the master suite amidships across the foyer, and the guest cabin to port. Each stateroom comes with HD screens, rich wood closet space, and en suite heads (the master with a his-and-hers).

    Ocean Alexander 78 Motoryacht master stateroom
    The full-beam master has a king-size bed and three large windows port and starboard. Forward are his-and-hers hanging lockers. Chest of drawers are built in port and starboard. If an owner cares to have a small nook with a table built in, that can be arranged. Same goes with a vanity or work station.

    In this image, we are looking from his wash basin, through the shower on the centerline to hers at right. Note the large window in the background -- there is one on each side. All faucets are by Grohe.
    Ocean Alexander 78 Motoryacht marble
    Looking forward from the master with the double doors wide open, we see the foyer with marble deck in the background.
    Ocean Alexander 78 Motoryacht guest
    The guest stateroom has ample width twin berths and a relatively wide aisle between them -- this is because of the boat’s 20’ (6.12 m) beam, which is 1’ to 2’ wider than most boats in class. Here is another place that beam pays off.

    VIP Stateroom.

    As in virtually all motoryachts of this type, the VIP stateroom is in the bow. In truth, not a lot can be done here to make this space much different one boat to another, but the folks at Ocean Alexander have tried. First, they have not crammed the cabin too far forward, which allows there to be a fair amount of space both port and starboard of the island berth. The lower halves of the hullsides are covered in the same Sapele wood that we have seen in the rest of the boat, and there is counter space port and starboard. Above that is a ledge with a stainless steel keeper that will be used to stow cell phones and the like. There are his-and-hers hanging lockers and a fairly large head with separate shower. There are no portlights in this cabin because Ocean Alexander has found over the years that they are vulnerable to water intrusion due to the very nature of their location.

    Engine Room and Crew Quarters

    Just abaft the master’s en suite head is the heavily engine room. The fuel tanks have been placed on the forward side of the engine room, thus creating an effective sound shield between the engines and the master stateroom. Behind the engine room is the crew’s quarters. There, we find two bunk beds, a full head, and a mini-galley with microwave, sink, and refrigerator.

    The opening portlight will give the crew some welcome ventilation.


    The 78 Motoryacht is equipped with two Caterpillar C32 ACERT 1622-hp engines and comes with two Kohler 32 kW generators onboard as well. We have not tested the Ocean Alexander 78 Motoryacht, but the folks at the company have. They report that the boat will make 24.5 knots at 2300 rpm. Further, they say that the boat has 425 nautical mile cruising range at 20 knots. We were not told what the load factor was in the tankage.

    Standard Equipment

    The Ocean Alexander 78 Motoryacht comes standard with a long list of equipment that is often optional on many yachts in class. For example, she comes standard with two Kohler 32 kW generators, stabilizers, thrusters, and a hydraulic anchor windlass. Contact Ocean Alexander for a complete list of standard equipment.


    About $4.5 million.

    The 78 Motoryacht’s anchor ship’s through-the-stem, which keeps a mess off of the deck. Her bulwarks and rails forward make working on the bow secure.


    With its 2,000-gallon (7,571 L) fuel capacity, rugged construction, and systems redundancy, the Ocean Alexander 78 Motoryacht is ready to go nearly anywhere the owner wants. This is what the brand is known for. Her styling is modern without garish flourishes, and so she should age well and not become dated as some large motoryachts have become.

    Every boat is a compromise

    , and this one is no exception. Clearly, Ocean Alexander has decided to target this design more to people who are serious boaters and who understand that the interior space is limited and must be used for the greatest utility possible. It has, therefore, omitted a formal dining area, choosing instead the country kitchen layout. Those wanting a more formal dining venue should turn the aft deck into that space by means of some modifications that we have pointed out.

    To Enclose or Not?

    Making the decision to go with the enclosed flying bridge or an open one is more difficult, it seems to us. We like the breeze and “openness” of the hardtop version, yet the enclosed model with its large windows and excellent visibility is also compelling. Perhaps a suitable compromise is a well-made set of polycarbonate curtains to surround the helm of the open model. We have navigated in chilly weather behind isinglass and found it not uncomfortable with a proper coat. In rain and fog, however, it is problematic. The choice of a single upper helm or an upper and lower is, we think, an easy decision. The lower helm eliminates a proper and comfortable inside dining table, so we would go with the single helm on the flying bridge.As far as the equipment goes, we are big fans of the Cat 32 ACERT engines, as well as the Kohler generators. Both the fuel and black water capacities are appropriate for this size boat, but we’d like to see the freshwater capacity increased to 650 gallons (2,460 L) or so. Few builders do that these days, but with a laundry washer, dishwasher, and six people showering, water goes fast. Certainly a large capacity watermaker is in order for anyone planning on cruising any distance in locations where freshwater is limited.
