2021 Beneteau Oceanis Yacht 54: The ‘Monomaran’ Alternative

Chris Block tours S/V Sea Dawgs — a push-button, teak-decked monohull with catamaran-sized beam and a superyacht dinghy garage.


When Chris Block of The Multihull Company steps aboard a monohull for a walkthrough, it’s worth paying attention. His pitch for the 2021 Beneteau Oceanis Yacht 54 S/V Sea Dawgs is straightforward: if you’re torn between a traditional sailboat and a catamaran, this 54-footer bridges the gap so convincingly he’s taken to calling it a “monomaran.”

The numbers back him up. With a 16.5-foot beam, Sea Dawgs rivals the footprint of smaller cats, and the interior volume shows it the moment you drop below.

A Superyacht Feature at 54 Feet

The headline trick is the transom garage. One button drops the platform, revealing enough space to stow an 8.5-foot dinghy — or something larger, deflated — inside the hull. When it’s closed, you have a proper swim deck; when it’s open, you’re spared the eternal sailor’s headache of a tender hanging off davits. It’s the kind of feature typically reserved for boats several price brackets up.

Push-Button Sailing from Twin Helms

Dual helm stations each carry their own B&G chartplotter, fly-by-wire throttle, bow thruster controls, and buttons for the electric winches, hydraulic tables, and swim platform. A self-tacking jib track and electric furling — including a roller-furling mast — make this a boat one or two people can genuinely manage. Adjustable jib cars led back to the cockpit hint at a more performance-minded setup than the family-cruiser reputation might suggest.

The full cockpit enclosure includes a dodger with clear windows that roll up tidily for fair-weather sailing and deploy quickly when the weather turns. Real teak runs from stern to bow — yes, it needs attention every six months, but the aesthetic payoff is real. A custom Starlink antenna keeps the boat connected offshore.

Living Space That Forgets It’s a Monohull

Below, the wide companionway opens onto a saloon that genuinely feels catamaran-scaled. A C-shaped galley with sturdy handholds is set up for cooking underway. The owner’s lounge doubles as the nav station. Two aft queen cabins each have their own en suite head, and the forward owner’s suite splits the shower and commode to opposite sides for privacy and light. A crew cabin forward — currently swallowing a Code Zero and assorted gear — can be reconfigured as captain’s quarters.

Mechanically, a 110-hp Yanmar sits under easily accessed panels at the base of the companionway — routine service without the usual contortions.
