For example, deep V-design hulls have a tendency to roll and incur high hull resistance. Flat-bottom hulls offer less resistance but pound in normal sea conditions. Thus, Hatteras has developed a series of convex and modified-V hulls that provide the best of both designs. These hulls deliver a sharp entry and a soft, stable ride - the renowned "Hatteras ride." Further, most Hatteras hulls feature a double chine with hull side "step-outs" to help reduce spray while increasing the beam above the waterline. The benefits - a dryer ride and more interior space.
Hatteras also uses in-house designed 6- and 7-bladed propellers custom built to company specifications. These propellers are dynamically balanced to effectively match the boat's weight, speed, horsepower and reduction gear. Using large blade area ratios, the propeller's load is distributed over a greater prop area. This reduces vibration and noise and, at the same time, improves fuel economy and performance.
Hatteras engineers specify deep gear ratios combined with larger propellers to obtain optimum performance.
Hatteras also uses a 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. The company installs 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 rudder bearings - not plastic bearings that may deform over time.
All wire and cable, regardless of applied voltage, is U.L. listed to 300 volts or more (often to 600 volts) to provide greater insulating protection. All wire is tin-coated (to prevent corrosion) stranded copper (for improved flexibility) and sealed in an insulated jacket.
Chafing shortens the life of wires. So Hatteras installs anti-chafing protection on wires that penetrate bulkheads or stringers or cross other sharp edges. They use insulated wiring clamps, nylon tie wraps, insulated bushings and silicone bedding compounds to protect the wires and extend their life.
All Hatteras wiring harnesses are tie-wrapped every 6 inches and secured at least every 18 inches - even when these wires are concealed in wire trays and ducts. You'll find no loose wires just stuffed out of sight on a Hatteras. All wiring is color coded and numbered at each terminal end and well documented in the owner's manual. System Protection Hatteras uses AC and DC magnetic circuit breakers that respond only to the amount of current flowing through the breaker, versus thermal circuit breakers that respond to temperature as a function of current. Magnetic breakers are much more reliable, as thermal breakers may trip prematurely in ambient temperatures. Hatteras magnetic circuit breakers are front-wired and back-mounted in aluminum panels for ease of maintenance.
