LUXURY, COMFORT, SAFTEY
Hampton’s Endurance line is focused on meeting the requirements for long-distance cruising in luxury, comfort, and safety. These mission-specific yachts are designed by noted naval architect, Howard Apollonio, an acknowledged expert in producing highly performance-efficient hull forms.
The Endurance family of hulls utilizes a hybrid form that delivers the fuel economy and seakeeping ability of a full displacement hull for longer, open water passages, along with the potential for the higher speeds of a semi-planing form for alongshore travel and island hopping.
Extensively tow-tank tested, Endurance hulls achieve unparalleled all-around performance for yachts of their size and type. And further refined by extensive real-world trials, Endurance yacht have proven themselves in delivering a unique blend of displacement and early-planing performance.
The Endurance Hybrid hull form is derived by eliminating the forward part of the chine. Then, reshaping that part of the hull to embody the best of characteristics of high-performance displacement hulls. Which significantly reduces resistance in the pre-planing speed range, typically 12-20 knots. The hull’s remaining chines aft work to reduce squat and aft trim and enable Endurance yachts it to run exceptionally well at early planing speeds. At the same time, the Endurance’s proprietary hull form matches or exceeds the fuel economy of full-displacement hulls when operated at the same speeds.
But the Endurance story involves much more than just the standout performance of the hybrid hull form. Beyond the hull form, these yachts incorporate construction features that yield strength, durability, and longevity – features like solid FRP laminate right from keel to the main weather deck, with fully-bonded longitudinal and transverse top-hat stiffeners; the inclusion of several layers of strategically placed Kevlar (aramid) fabric reinforcing for enhanced puncture and collision resistance; and generous use of vinylester resins in their hull skins, both inside and out, for better wet-out and superior bonding of the protective Kevlar layers and for higher resistance to water permeation and potential osmotic blistering.
BUILT FOR THE SEA
Endurance hull sides are solid laminate above the waterline and composed of a minimum 5 layers Knytex (or Cymax) glass reinforcing. Unlike many other yachts, Endurances are not cored below the rail, but are solid laminate all the way down from the toe rail to the bottom of the keel. And the Endurance hull/deck joint is through-bolted every 6″ and sealed with 3M 5200 polyurethane adhesive, then glassed over with 3 layers of fiberglass.
Endurance decks and superstructures are cored with high strength Core-Cell Foam. And the saloon sole over the engine room is fitted with an additional six inches thick sound-attenuating materials for the ultimate in quiet operation.
All tanks aboard an Endurance yacht are molded in fiberglass laminate using Vinylester resin. Then a food-grade resin is applied to all interior surfaces of the potable water tanks, and a fire-retardant mixture is applied to all fuel tank exterior surfaces to improve their flame resistance. All tanks are then pressure tested to ensure quality.
From their carefully thought-out deck and equipment layouts to their skillfully engineered propulsion packages, Endurance yachts are built to go to sea. Critical safety features are never overlooked. In all Endurance yachts, you find watertight anti-collision bulkheads, multiple escape hatches, fire detection and suppression systems, a custom ship’s monitoring system, and twin anchors rigged with 300 feet of all-chain rode running over link-matched hydraulic windlasses.
