Designed as a world cruising and personal exploration vessel, the Explorer class is for adventurers who want to circle the globe. It's heritage is from the offshore supply vessels and the working fishing fleets of the Pacific Northwest. A robust ship of proven seakeeping ability she is fitted with a bulbous bow and Kort nozzle for efficiency as well as roll reducing twin keels. She will be the primary residence for an experienced owner with ocean cruising under his belt. The extensive range, on-board watermakers, and great storage capacity make trans - ocean crossings a matter of course.

The large machinery space is fitted with twin slow-turning diesel engines and twin generators with dry stack exhausts. A hydraulic cruising generator as well as a hydraulic 'come home' powering system are specified. Aft of the engine room is a large workshop and storage room. The accommodation level has four staterooms with an on-deck master suite. The main deck lounge opens out onto the main deck where the personal sub, seaplane or helicopter, jetskis, windsurfers, kayaks, and dinghies are to be kept. With the equipment off-loaded this area becomes a 26' x 40' sunning and activity area. Tennis anyone? The professional galley and dining room are forward and occupy the full width of the ship. The bridge has direct access to the anchor windlass forward, the side decks, the aft wing stations, and the upper aft deck. The helm area is large and complete with chart table, electronic charting, flag lockers, and radio communication area. There is plenty of room for guest seating in the observation areas as well as a captain's or owner's cabin aft. The upper aft deck overlooks the main deck, for spectators and sun worshippers who do not want to be disturbed. Up the outside staircase to the large flybridge you will find a barbecue, dinette, and settee under the permanent sun top. Many bridge controls are duplicated here for running the ship from 'up top'.

The steel hull and aluminium superstructure have over 4" of insulation as well as double paned windows for maximum comfort in all climates. There are four watertight bulkheads and the vessel meets the ABS Rules for Motor Pleasure Yachts of unrestricted service. All equipment on board from anchors and rode to the fire fighting and emergency bilge pumping system are 'big ship' design. The piping and wiring are also of commercial standard.

The Explorer is a rough, tough, no nonsense, go anywhere class of vessel with the comfort and equipment to do it in style. The raised bow and protected side decks challenge the sea and the high bulwarks protect the sailors on board. The covered decks shield from rain and sun to meet the demands of a wide range of climate. Once at a remote anchorage, equipment can be lowered off the main deck to explore the depths, play in the wind and waves, or fly off for a picnic on an untouched beach.

 
 
Hull Engineering, Design and Construction

The Explorer series hulls are designed using the latest technology in offshore vessels. We use the B.C. Research model test tank (at the University of British Columbia) to develop our advanced hulls for optimum efficiency.

Hull and deck are designed and built to American Bureau of Shipping Rules for Unrestricted Offshore Motoryachts and the recommendations of the American Boat and Yachting Council. The full displacement hull features pitch and roll-dampening fixed twin keels which reduce resistance, increasing cruising speed without increasing fuel consumption. They also allow the use of unimproved yards dependent on tides, or even a tidal beach for haul-outs.

The hull, with widely flared bow sections, has great reserve buoyancy for lifting to head seas. Positive stability is achieved well beyond 150 degrees making the ship self-righting in extreme conditions. It is engineered for integrity in all weather conditions to ensure survivability in breaking seas, and employs a spray knocker to reduce spray on deck.

We use the new Bray Tunnel Enclosures around a large diameter highly skewed propeller, developed from technology used on the whisper quiet stealth submarines. Using a very slow rpm we can greatly increase propeller efficiency while reducing noise. This also enables the ship to drive into head winds and big seas without a change of speed. Cruising speeds of 14 knots without the penalty of excessive fuel consumption are possible using these systems.

 
Engine Room and Mechanical Systems

The engine room has full headroom with easy access without compromising accommodations. It is "clean" and free from a complexity of valves, wiring, and switches, carefully utilizing enclosed, planned panels for ease of access. Automatic and manual fire fighting systems are standard.

We use heavy duty diesels with large reduction gear to turn our propellers. A flexible shaft coupling is used in conjunction with soft engine mounts that are essential to reduce engine room noise and transmission into the accommodations. The ship achieves near silence while underway in all accommodation areas. Dry-stack exhaust is standard to reduce exhaust back pressure and noise, increase engine efficiency and life, and for the removal of exhaust gas emissions from the boat deck. Engine cooling systems are simplified using keel coolers which extend engine life by eliminating salt water.

Fuel and holding tanks are integral to the hull with sight gauges on the fuel tanks. Water tanks are stainless steel. All tanks have access for clean-out. The ship uses Sea-chests with all salt water entering from a single thru-hull into two accessible columns, eliminating multiple hull openings. Heavy plexiglass is mounted on the top for viewing into the chests and the tops can be removed while the vessel is afloat for maintenance and cleaning out.

An engine replacement system is designed employing hatches in the deck. This unique and valuable concept will be greatly appreciated when major mechanical change-overs are necessary.
