Maritimo stuns with eye-opening 440 IPS Offshore Convertible

Australian boat-building legend Bill Barry-Cotter has stunned the luxury boating market again with the launch of his revolutionary new Offshore Convertible at the Sydney International Boat Show.

The new 440 Offshore Convertible  – complete with internal staircase, an enclosed flybridge and a three-cabin layout – offers an extraordinary level of space and comfort in a 44-foot cruiser.

It includes a revolutionary aft bulkhead design featuring bi-fold doors that tuck away to open the saloon out to the aft cockpit. The design was introduced on the Maritimo C47 Sports Cabriolet.

This exciting new model offers a vast array of features only previously seen on much larger boats. These include:

  • A three-side enclosed flybridge
  • Internal teak-tread staircase
  • Aft galley
  • Bi-fold doors opening the saloon to the cockpit
  • Three cabin/two bathroom accommodation
  • Volvo Penta IPS propulsion

This boat will include positive buoyancy tanks in the engine room, a safety feature first incorporated into the C47 Sports Cabriolet.

Adaptable for big game sportfishing, family weekends away or long-distance cruising, the new Maritimo 440 Offshore Convertible will comfortably sleep five in three separate cabins.

Powered by twin Volvo Penta IPS 600 systems, the 440 Offshore Convertible has a fully equipped galley in the aft quarter of the saloon including four-burner electric cooktop, microwave and standing refrigerator/freezer built into a space under the flybridge stairs as well as ample storage.

The spacious saloon, forward offers an L-shape leather lounge to starboard with an L-shape dinette to port.

Forward, three steps down a central companionway, the accommodation includes a master stateroom forward with a walk-around queen double bed and spacious hanging lockers on either side. An en-suite bathroom is on the port side, equipped with a separate shower stall with frameless glass door, electric toilet and a vanity. Fixed portlights in the hull provide plenty of natural light in this stateroom even when the deck hatch is sealed.

Midships port and starboard are flooded with natural light through large portlights in the hull. The port cabin includes an athwartships double with the option of an additional single bunk above the foot of the bed. The starboard cabin is a single bunk.

These two cabins share the second day bathroom on the starboard side, forward of the midships cabin.

The enclosed flybridge is reached via an aft-facing teak tread moulded staircase in the port aft corner of the saloon. It features an aft helm position so the skipper has great visibility both forward and aft. A deck immediately behind the helm is a great viewing platform for game fish action or for simply soaking up the sun. Seating for guests is forward of the helm.

With a fuel capacity of 2,000 litres, the new Maritimo 440 Offshore Convertible has been designed as an ideal family boat.

Base price of the new 440 Offshore Convertible is a highly competitive AU$850,000.
