Ocean Explorer Wins Baird Maritime Award

Designed by One2Three Naval Architects and built by Queensland boat builders Commercial Marine Australia and Wildcat Marine, Ocean Exploer is a tourism dive boat constructed for a Whitsunday Island resort. Designed to be not just capable, but with comfort and economy in mind, the Ocean Explorer has a top speed of 25 knots and a cruising speed of 20 knots. A fantastic looking boat with some great features all the companies involved have outdone themselves with this vessel construction. 

MAFI grilles mounted in the side of the boat.

Marine Air Flow's Ventilation System Details


This engine room system is a little unusual in that the Air in is aft (or to the rear) of the air out.


The reason for this is the air out duct also doubles as an entry into the engine room, so this system was designed that the supply air fans would be safely aft in the engine room. This located them away from the crew access, enabling the fans to push the air forward over the engines and out though the air out grilles that are just behind the cabin area.


The air out system also incorporates our brand new "man access" drop flap system. These drop flap dampers have been designed to allow crew access to the engine room while also providing the ability to the close off the air duct in case of a fire.
