Featured marine light aluminium boats From Recognized Brands - myboat039 boatplans Jul 30, �� The biggest advantage of aluminum boats is the reduced weight. Aluminum watercraft is % lighter than fiberglass boats of comparable size. Compared to steel boats, aluminum boats have % less weight. This reduced weight makes aluminum boats more fuel-efficient. They require smaller and lighter engines, are faster, and can carry more weight. Jul 20, �� When I was out with Madcatter on the 4th, he said if you can see the lightning streaking in the sky, it is time to go. I asked him about this because at the time, we could see flashes all over the place and his boat is aluminum. Shortly there after, we boogied off the river because we started seeing the streaks of lightning all over the place. Feb 10, �� One in 1, Boats Are Hit by Lightning Per Year Boat U.S. gathered insurance claim data from a year period and found that the odds of being struck are about one in 1, in any given year. Location, however, matters a great deal. Florida accounted for 33 percent of all claims, and the Chesapeake Bay area accounted for 29 percent. Boating.

I heard that most lightning strikes hit 7 miles from the storm--in other words, bolts are hitting all around it, not directly under the dark cloud. That's why you move out at first sign.

Here is a good article on the effects of lightning. Actually and aluminum boat is good because it dissipates the energy into the water. You don't want to be sitting there holding onto metal though.

I would think if you had a bimini top, if it was up it probably might create what the call a Faraday cage effect where the frame might offer a quicker path through the boat to the water. If I hear lightning forecast I pick another day or head in the opposite direction for another lake yet boaters in places like Fl which is the lightning capital are out there all the time.

If they did not go out with a forecast of lightning they would never be able to go boating. Still, I've been on boats in Fl trying to out run the storms which you can see coming miles off on the open ocean, but once you finally get to the shore and head down the canals the Manatee warning signs say 5 mph. Fl is not my idea of good times for boating unless the boat is big enough to have a mast that transmits the lightning strike down a wire into a big plate mounted to the boat under the water line that channels the hit into the water.

Still can do a lot of damage to your electronics. CATransplant Admiral. Joined Feb 26, Messages 6, If you can see the lightning or hear the thunder and the storm is heading your way, it's time to head for the dock.

Fishing and boating are wonderful, but hardly worth dying for. If there's a storm coming, get off the water. It's that simple. Think about how long it will take you to get to the dock or ramp. Leave before it's too late. CATransplant said:. However, often not practical. Especially on the stretch of River I run. For Murphy's sake, I run upstream from my launch point. With the topography here you often do not get much warning, and to "run for the dock" most times you would be running into the storm.

Same difference. Likewise, being a pre-retirement person, if I wait for the "perfect day" I would be lucky to get out 5 days a season. That just leaves dealing with the risk as best you can.

Issues such as corrosion damage to the metal, temperature control within the cabin, and plain design aesthetics are common with aluminum boats. The biggest cause of corrosion is electrolysis. Electrolysis occurs with two dissimilar metals are in an electrolyte. Saltwater is a much stronger electrolyte than freshwater, and boats often have stainless steel or bronze hardware attached to the hull.

These can set up corrosion by electrolysis. Even a copper penny lost in the bilge can cause corrosion. The Zinc will corrode in the electrolysis process and protect the aluminum hull. Zincs must be examined and replaced because they are designed to corrode away. Many aluminum boats suffer from corrosion in the shaft tube. Inboard powered boats can have corrosion problems, especially in the propeller shaft tubes and rudder bearings.

Stainless steel prop shafts live close to the aluminum in the shaft tube. Rudder shafts are often stainless steel as well. These are potential corrosion areas that are not readily visible. Be sure to check these areas often for corrosion or degraded zinc anodes.

Another cause of corrosion is electrolysis from faulty wiring. Any currents that flow from the aluminum hull to other metals in the area will cause corrosion. Again, zincs will handle the corrosion, but they may rapidly disappear if there are stray currents.

Be sure all electrical equipment is well-grounded and insulated. If you suspect stray currents in your marina, ask a specialist to measure for the problem.

Age and hammering through waves can cause these boats to leak at the panel joints. There is no easy way to repair this permanently. Another way to stop the leaks is to thoroughly clean and dry the area around the leaking seam.

In a boat, the "cage" is formed by bonding together, with heavy conductors, the vessel's mast and all other major metal masses. A marine electrician must tie in the engines, stoves, air conditioning compressors, railings, arches etc.

It is important that you ensure that your crew fall within the protection of the "cage," something not always feasible when the vessel is not built of steel or aluminum. On NON ALLOY or wooden boats it is advantageous to have a mast or other conductive metal protrusion extending well above the vessel, creating what is known as a "cone" or zone of protection. It is generally accepted that this cone of protection extends 45 degrees, all around, from the tip of the metal protrusion.

This means that if the aluminum mast of the average sailing vessel is properly bonded to the vessel's other major metal masses and is given a direct, low-resistance conductive path to ground, the entire boat should fall within the protected zone. If the vessel has a wooden or composite mast, a marine electrician can achieve the same effect by installing a 6 to 12 inch metal spike at the top and running a heavy conductor down the mast and as directly as possible to ground, usually through the engine and propeller shaft.

Again, refer to the ABYC standards and have a professional marine electrician install your lightning protection.

I encourage everyone to look him up! Here is a brief description from Wikipedia: A Faraday cage or Faraday shield is an enclosure formed by conducting material, or by a mesh of such material.

Such an enclosure blocks out external static electrical fields. Faraday cages are named after physicist Michael Faraday, who built one in An external static electrical field will cause the electrical charges within the conducting material to redistribute themselves so as to cancel the field's effects in the cage's interior.

This effect is used, for example, to protect electronic equipment from lightning strikes and other electrostatic discharges. What a guy! Read up, enjoy the history, and feel safe in your alloy boat!

High tension wire maintainence by humans dropped off by helicopter onto the live wires protcted only by a stainless mesh suit acting as the faraday cage. The chopper approches the wires and the worker holds out a rod to discharge the static charge.

Quite as site! Post by Ironwoodtuna � Tue Jan 15, am Like the article says stay away from lightning. Easier said than done, but the best tool I have found and most accurate is the Garmin C XM Weather fax which shows me the realtime weather including lightning strikes. I have used this realtime information on Aluminum Boats And Lightning Frames it's screen to take the boat back home through open lanes with lightning strikes being shown on both sides of the boat and in the visual real world I was in the safest lane to return home.

I knew I needed to get back to port as quickly as possible hopefully making it back to port before the storm hit us. This storm moved like greased lightning. It was on us in minutes and thank god for the unit, I saw a path like going down the throat of it and lightning was all around us, but never really that close to us. Thanks Garmin, I also have used it off in the canyons to run NM one direction or another to get out of the path of a cell moving through. Its well worth the monthly fee and I get XM radio out there in the canyon.

I move it from my truck to the boat during the week. An as the shield protection in my boat I do feel as safe as anyone could be.
