1. CONGRATULATIONS  You own the most powerful hydrogenerator of its kind. Designed for transoceanic racing and cruising, this device will drastically change your energy management at sea and become your main source of power while sailing. Designed and made in France by: WATT&SEA SARL Le Sextant 1 rue de la Trinquette 17000 La Rochelle FRANCE www.wattandsea.com

2. SAFETY  “Safety first” was our goal in building the hydrogenerator. However precautions must be taken as when using any mechanical or electrical device. Keep in mind safety rules when installing and operating the hydrogenerator. Be aware at all times of hazards in operating the propeller. While rotating, propeller blades might be dangerous. They are aluminum made and their edges can rotate up to 62 MPH (100km/h). At this speed, the tip of a blade is nearly invisible and can cause serious injury. Under no circumstances should you install the turbine where a person could come in contact...

5.1. Installing the propeller. • Slide the propeller onto the shaft • Check that the electrolytic insulation washer is placed into its groove • Insert the CHC M5X20 screw, and tight it with a 4mm Allen wrench. We recommend coating the screw with block thread to prevent the screw from loosening. W&S - Manuel GB Cruise v1.2 page 8 by 24

Choosing the right place for the machine is crucial to optimize its performance. Be careful to respect the following conditions:  Immersion depth: The recommended depth from surface to propeller axis is 30cm (12 inches). The machine comes with a profiled 1 meter aluminum bar that can be cut to fit any configuration. The deeper the device is located and the farther the propeller is from the hull wake, the better it is. However, the deeper the boom is, the more stress on mounting will result. In addition, the device will be harder to lift. We consider that a length of 1 meter (3.28 feet) is...

Example of installation with shorter shafts (70cm): Fig. 4 : Double installation on a Pogo40 (© CN STRUCTURES). The hydrogenerators are placed parallel to the rudders but off their wakes. Fig. 5 : Installation on a catamaran. (© OUTREMER CATAMARANS) The hydrogenerator is placed parallel to the rudder but off its wake.

Depending on your transom structure and to ease stress on the cradle plate, you might need to reinforce the structure of the transom. WARNING : Because the lever arm is important, the maximum effort in cradle’s fixations is around 300 kg (661 pounds). Your mounting system should be designed accordingly. The cradle must be fastened to 8mm chainplates that will be securely mounted on the transom. Chainplates must be placed vertically. Use the drawing below to adapt the mountings to your boat. NOTE: when immersed in working position, the shaft must be vertical.

Your hydrogenerator comes with a lifting system designed after lifting rudders systems. It allows easy access to the propeller when the device is in upper position, which allows weed cleaning without leaning over board. We recommend inserting a self-release clam that will release the device when running against an immersed hard object. Immersion and lifting are performed with 2 lines attached into specific eyelets. Fig. 7 : Immersing/lifting lines path Lifting weight is around 40 kg (88 pounds). We recommend to placing a 4:1 pulley hoist for easier lifting of the device, and a 6:1 for the...

To remove the propeller, you should use a M6 screw as an extractor tool.   Unscrew the M5 screw that holds the propeller at the very end of the shaft. Next, insert a M6 screw and tighten it with the appropriate wrench; this extracts the propeller effortlessly from the conic shaft. The electronic converter is fitted into a waterproof box that features passive ventilation allowing long durability of the device in a humid environment. However this converter must be affixed inside the boat, preferably near the battery to be charged. WARNING: THE CONVERTER CAN REACH A HIGH TEMPERATURE WHILE...

6. ELECTRICAL INSTALLATION  Recommendations regarding electric connections: Please follow local/national safety rules before installation. All electric cables must be carefully insulated. For the highest safety, insert cables into plastic conduits. WARNING: CONNECTIONS MUST BE CHECKED ON A REGULAR BASIS TO DETECT ANY EVIDENCE OF CORROSION, AND CLEANED WHEN NECESSARY.

WARNING: LIFT THE GENERATOR UP BEFORE ANY OPERATION The hydrogenerator comes with a small diameter electric cable located at the bottom, long enough to get through the transom. This cable features a 3-phase wiring identified in black, brown and grey colors. A green & yellow wire can be found for ground.  After this transom point, connect a tri-phase cable of a larger section (minimum 3X2.5mm2) between the hydrogenerator and the converter. NOTE: a cable of a smaller section than 3X2.5mm2 will affect the output of the device as well as its performance.  We recommend to connect the cables in...
