Our master craftsmen, designers and engineers utilize only the highest grade materials and quality parts to assure that all mechanical components work reliably and in harmony. We go to great lengths to not only design and engineer systems that exceed industry standards, but also assure your safety and ease of operation every nautical mile.
Rudders and Propellers
Hatteras uses a pultruded fiberglass rudder shelf that provides a strong, stiff, well-finished part. No plywood (that may rot), corrosive aluminum or similar metal is used here. Stainless-steel rudder tie rods are used exclusively rather than milled steel tie rods, which deteriorate with saltwater exposure.
Each rudder and stock is cast as a one-piece bronze part, eliminating any potentially weak bonds. We install a locking collar and thrust washer on the rudder stock at the rudder port, as well as the rudder shelf. This permits the hull bottom to carry the weight of the rudder and reduces vibration in the rudder shelf. Hatteras uses orcot rudder bearings - not plastic bearings that may deform over time.
Hatteras machines all propeller shafts in-house, from the highest grades of austenitic stainless steel. The superiority is a result of its corrosion resistance and its ability, for a given size, to withstand the stresses and torques created by today's higher horsepower engines and deep gear reduction ratios.
Included with each new Hatteras is a prop puller/pusher that ensures optimal surface contact between the shaft and propeller hub. The same mechanical advantage that is used to create an extremely tight custom fit also facilitates ease of prop removal.
Hatteras utilizes polyethylene tubing for fresh water in lieu of copper or polybutelene for reduced corrosion and resistance to damage in cold weather climates. For additional purification, Hatteras uses a charcoal carbon freshwater filtration system with back flush capability. We do not use single paper filter.
All of our models include duplex fuel/water separating filters for engines and generators, hydraulic power-assisted steering, fuel priming system, and a water-fill hose in the engine room.
Most of our yachts incorporate the use of a water manifold block to distribute fresh water throughout the boat. This system allows for fewer fittings and leak possibilities, and enables you to isolate and shut off a particular system to solve a problem, while leaving the rest of the boat's water system intact. You don't need to turn off all the water to fix a problem.
All mufflers and exhaust tubes are built out of fire-retardant fiberglass and customized for each engine installation, ensuring optimal sound reduction, maximum usable space and minimum exhaust back pressure. Our side exhaust outlets are designed so that the majority of the opening lies underwater at idle speeds, thereby directing exhaust away from the vessel into the yacht's slipstream to reduce odor and soot in the cockpit.
All Hatteras generators have sound shields to reduce noise, and on all convertibles the discharge exhaust is just forward of the engine exhaust, providing a clean hull side. Exhaust tubes are run separately from the main engine exhaust system to eliminate exhaust contamination to either the main engine or generator when both are not operating simultaneously.
Comfort and Safety
Hatteras air-conditioning capacities are designed to provide comfort in even the most difficult areas. Hatteras uses an air-conditioning control system that allows most staterooms to control both the climate and fan speed individually, not just the fan speed.
An integrated smoke detector system with units installed in each stateroom and some common areas is linked to the systems monitor. Each smoke detector unit will sound individually, as well as via the systems monitor.
We design and install an automatic fire suppression system with automatic and manual activation, both of which trigger the system monitor. Once the system is activated, all engines, generators and blowers are shut down and the fire-fighting agent is dispersed. Thus, engine air intakes or blowers are not operational to ingest or dilute the valuable extinguishing agents.
Hatteras uses fire-resistant, steel-braided, high-pressure hydraulic hoses with brass or stainless-steel fittings throughout the steering system.
As you can see, quality, strength and safety are far more than a Hatteras tradition. They are an obsession.
