Watch the Weather.   Even the best-laid plans for the perfect boating outing can be turned upside down by Mother Nature. Watch the sky. Know what to look for in clouds. Be very conscientious about spotting lightning. It never hurts to know as much as you can about the weather. Courses are available at local colleges and online on what to look for in the sky and plan for weather fronts that can change on a dime.   The odds of your boat being struck by lightning are about one in 1,000. However, your odds are skewed, depending on your location. If you are in Montana, you have good chances that it won't happen, but in a popular boating state like Florida, surrounded by water, you will have less luck. One-third of the country's lightning insurance claims are filed in Florida.     According to William J. Becker, University of Florida IFAS Extension, in a report for the National Association of State Departments of Agriculture, NASDA, Florida averages more than ten deaths and thirty injuries from lightning per year. Approximately fifty percent of the deaths and injuries occur to individuals involved in recreational activities. Nearly forty percent of those are water-related: boating, swimming, surfing, and others.   Sailboats are more likely to be struck than powerboats because lightning is attracted to the mast. In the powerboat category, trawlers are struck more than other powerboats.   What is Happening When Lightning Strikes?   Becker describes it as, "The upper portion of the cloud develops a positive electrical charge, the lower level a negative electrical charge.  Because it is a poor conductor of electricity, the air restricts the regular flow of electricity between these, attracting electrical charges. While this phenomenon is occurring in the clouds, a similar event is occurring on the surface. Negative charges repel negative charges and attract positive charges. So, as a thunder cloud passes overhead, a concentration of positive charges accumulates in and on all objects below the cloud. Since these positive charges are attempting to reach the negative charge of the cloud, they tend to accumulate at the top of the highest object around. On a boat that maybe the radio antenna, the mast, a fishing rod, or a person!"   Lightening makes its own Schedule.   While you can take steps to lessen the damage lightning will cause, you can't prevent a strike.   What happens when your boat is Struck?   NOAA, the National Oceanic and Atmospheric Administration, www.noaa.gov., estimates a strike contains around 30,000,000 volts. Your boat's electronics are most susceptible to damage. Most 12-volt electronics will be damaged, if not all, electronics on your vessel.   At times, the strike will hopscotch around the boat, and collateral damage occurs when a nearby vessel gets hit, either the result of the lightning's powerful electromagnetic field or the current induced by the field running through the boat's shore-power cord. Some electronics will be damaged; others will not. Check your compass. There may be no external damage, but the compass heading significantly affected.   Precautions to Reduce Personal Injury and Damage from Lightening.   When a thunderstorm of any kind is approaching, whether lightning is present or not; Get everyone out of the water – scuba divers, swimmers, jet skiers, and stop any fishing activities. Stay in the center of the cabin of the boat. Keep arms and legs in the boat.    There is no such thing as a boat being lightning proof, but you can take steps to make your vessel lightning protected. Most pleasure craft are made of fiberglass or wood, not providing the automatic grounding protection offered by metal-hulled craft. When lightning strikes a small boat, the electrical current is searching for any route to ground, including the human body, an excellent conductor of electricity.     Major lightning protective equipment includes an air terminal, main conductor, and a ground plate. Secondary components are secondary conductors, lightning arrestors, lightning protective gaps, and connectors. Lightning arrestors and lightning protective gaps are used to protect radios and other electronic equipment, which are subject to electrical surges.   If a sailboat mast is made of conductive material, a conductor securely fastened to the mast and extending six inches above the mast and terminating in a receiving point, or a radio antenna can serve as the air terminal.   Captain Chuck Reed, and his wife, Linda, sailed their 36' Catalina sailboat from Detroit to the Caribbean and lived aboard for three years. Reed, the owner of CLR Marine, used a shaft saver on Silent Dream to to keep the boat totally ungrounded, and also save the prop shaft if a line got wrapped around it. Yes, it did save the prop shaft one time and being totally ungrounded he feels that it did save them from the lightning. The Reeds encountered many thunderstorms that included lightning, their boat did not suffer any damage due to lightning.   The National Fire Protection Association, Lightning Protection Code   For a more detailed summary of how to protect your boat from a lightning strike, refer to the National Fire Protection Association's Lightning Protection Code. www.nfpa.org.   Shaft Savers are available at https://www.clrmarine.com/462m4/marine-hardware/shaft-couplers.html    Watch the weather.

Flexible Shaft Coupling for 4" Yanmar - 3HP/100RPM Capacity The R&D Flexible Couplings are fabricated from a contoured flexible disc molded in tough yet resilient new type polyurethane. The contoured disc gives clearance for the bolt heads, and is able to flex freely to take up any temporary misalignment of the engine and shaft, due to flexing of the boat structure or the engine moving on its rubber vibration isolation mountings. Forward thrust is taken in compression on the disc between the two half couplings and reverse thrust is taken again in compression on the disc between the two fail straps. In the unlikely event of a disc failure the steel straps make the coupling fail safe and ensure drive is maintained in both forward and reverse. To calculate power of coupling required: Horse Power of Engine x Reduction Ratio x 100 = HP/100RPM       Engine Speed Example: Ford 150HP at 2500RPM with Borg Warner Velvet Drive 72C 2:1 Reduction Ratio Engine Horse Power is 150HP, Max Rated RPM is 2500, Reduction Ratio is 2:1 150/2500 X 2 x 100 = 12HP per 100RPM Coupling required is 910-009 The R & D Marine Flexible Coupling fits between the transmission output flange and shaft coupling. It is designed to protect a boat's drivetrain. The unit will reduce vibration, compensate for some misalignment, isolate the shaft and absorb shock loads. The flexible disc is machined from a resilient and durable polyurethane. It allows the unit to flex, absorbing vibrations and temporary misalignment of the shaft and engine due to movement of the engine or flexing in the vessel's structure. The polyurethane disc is backed up by two metal compression straps, one on either side of the flexible coupling. These metal straps hold the system in constant compression whether the drivetrain is in forward or reverse. This feature extends the life of the system dramatically. The R & D Marine Flexible Coupling will also absorb shockloads resulting from gear changes, or the propeller striking a submerged object. The polyurethane disk will distort with light shock loads and is designed to be sacrificial in the event of severe shock load, saving on expensive drivetrain repairs. If the disc is destroyed from massive shockload the metal compression straps keep the coupling intact ensuring that the drive system is functional in both forward and reverse. Why R&D Marine Flexible Shaft Couplings? Polyurethane flange creates a flexible barrier to reduce drivetrain noise and vibration to quiet your drivetrain Absorbs transmission shock load caused by the propeller and high speed gear changes. This helps to reduce and avoid costly transmission damage Fail safe design, both forward and reverse thrust is taken in compression from the steel straps, giving a durable design even in extreme conditions
