1 Our hydraulic systems mean superior performance, precision control, and a significant sailing advantage. Hydraulic challenges come in many shapes and sizes. So do our solutions

HYDRAULICS Every yacht design is unique, and every element of a Navtec hydraulic system is based on a complete understanding of that particular boat and its capabilities.

2 HYDRAULICS Every yacht design is unique, and every element of a Navtec hydraulic system is based on a complete understanding of that particular boat and its capabilities. Navtec also engineers custom hydraulic products to provide solutions to all marine applications. Please contact Navtec direct for all custom product questions. System 50 Hydraulic Panels It is the heart of a Navtec hydraulic system, putting the operator in complete control of up to four functions including halyards, cunningham, mast jack, traveler, vang, backstay or outhaul functions. System 50 is designed to meet the changing requirements of racing and cruising yachts in the 35- to 70-foot LOA range. Ease of operation. Controlled flow, gradual release valve. Speed. Faster flow rate = faster response. Optional auto-shift pump.two-speed pump offers high volume and fine pump functions with adjustable shift pressure. Power Interface.Leading winch powerpacks can interface with and be accurately controlled by the System 50. Protection.Relief valve provides immediate pressure release for the selected function. Finish.Black anodized or stainless steel. Reservoir. Standard on a single function is a two-quart reservoir; four-quart capacity is standard on a multifunction panel (209.6mm) 2.63 (66.8mm) (478.4mm) REF 7.25 (184.2mm) MIN INSTALL DEPTH "D" 5.68 (144.1mm) 6.57 (166.9mm) 8.50 (215.9mm) 3.14 (79.9mm) CUTOUT DIMENSIONS (ALL) (254.0mm) System 50 Hydraulic Panel Specifications MIN.

Multi-function panels can be used to control 1, 2, 3 or 4 hydraulic functions. The 2-speed Auto-Shift pump supplies 300% more flow at low pressure. Single-function panel assemblies include a 2-quart molded reservoir. Multi-function panels include a 4-quart reservoir. * 4-way valve is to control double-acting (push-pull) cylinders. N/A N/A

This is why the new System VIII panel is an ideal choice for Grand Prix and Super Yachts, which demand the highest level of performance available.

3 System VIII Lightweight Hydraulic Panels The System VIII panel incorporates new Cam Valve technology, developed by Navtec. Cam valves make the System VIII easier to use and more durable at higher pressures than competitive systems. This is why the new System VIII panel is an ideal choice for Grand Prix and Super Yachts, which demand the highest level of performance available. The System VIII offers improved design aesthetics and the same configuration offered in the System VII panels. The cam valves are sculpted to save weight and space. Each output has its own valve and gauge to monitor the function it is controlling and a relief valve that can be set individually. Flow control can be added to each valve by simply inserting flow control needles into the outlet of each valve. The new panels can be easily integrated with powered units provided by leading winch manufacturers or custom ship-system designers. System VIII panels come in multiple configurations. [See chart below.] Standard panels come with a hard-coated aluminum face plate.

THE INTEGRAL BACKSTAY ADJUSTER Ergonomics meets economics. The Series 8 Integral Backstay Adjuster incorporates several key design concepts.

4 THE INTEGRAL BACKSTAY ADJUSTER Ergonomics meets economics. The Series 8 Integral Backstay Adjuster incorporates several key design concepts. The pressure gauge is positioned prominently, enabling fast, accurate reading of tension values. A longer pump handle produces faster pumping motion and more tension per stroke, which delivers greater performance out of modern masts. The feed tube is seated into the contour of the cylinder, resulting in a more secure design and integrated look. In testing, the Navtec Series 8 Integral enabled sailors to increase rigging tension quickly, precisely, and easily. With each stroke of the handle, rake increases along with forestay tension, resulting in improved roller furling gear performance, sail shape, windward performance, and speed. Use of the specifically designed Integral toggle is strongly recommended.

"CLEVIS GAP" "PIN DIAMETER" BOOM VANGS A850 Vang Navtec's Series 85A Vang is more powerful, safer, and easier to use than its competitors, including mechanical vangs. It features an extra-large piston rod to resist buckling, no tackle to further clutter your deck layout, built-in protection from the relief valve on the panel to assure safety, and it also provides boom lift in light air and acts as a topping lift when the sail is flaked. Add a Push Button Quick Release Valve to instantaneously dump the vang when needed. Contact Navtec to help size a hydraulic vang option for your boat.

8 A254 Traveler Cylinder Navtec double rod cylinders were engineered and designed by Navtec for use in dual pull application, usually with a block and tackle incorporated. Navtec originally engineered these cylinders as a solution to operate main sheet travelers. They are also commonly used to operated genoa lead systems as well as many custom applications. Navtec will work with any marine hardware manufacturer to provide a cylinder that interfaces with their hardware to operate any double acting needs.
