So when you're list of on board electronics and gadgets looks like a summary of this website, how do you make sure interference won't be spoiling the party? Well, start by reading John Payne's electronics column in DIY boat owner magazine's 2004#1 issue.
"Noise sources on a boat are often classified as radio frequency interference (RFI) or electromagnetic interference (EMI). They are major enemies of electronic systems, corrupting your GPS position fixes, degrading radio communications and causing general electronics performance problems. RFI is essentially interference and noise that is superimposed as a disturbance or voltage transient either on the electrical power supply or the data and signal lines. This is then processed along with the good data to corrupt or degrade the processed information."
There's no question that the trend towards light-emittingdiode technology is very strong. I have covered it a couple of times already and the benefits are clear. Trailer Boats Magazine has discovered them as well.
"What would you say if I told you there were products for your trailer that would save you time and money, and make it look more attractive? And the best part is you can install these products yourself in a matter of minutes with simple hand tools. These amazing products are light-emitting diode (LED) systems. LEDs are certainly not new, but they have recently been incorporated into lighting systems for trailers, and these products are readily available at reasonable prices."
In Boating World Magazine's May Gear Locker they showcase a nice gadget that allows you to detect above-normal operating temperatures of your equipment.
"Being proactive can help you avoid major problems, including those that may occur in your engine compartment. Telatemp�s pistol-grip IR (Infrared) Thermometer gives an early warning of potential equipment failures by detecting above-normal operating temperatures. Its built-in laser pointer allows you to pinpoint specific locations on machinery. Basic accuracy is +/- 2 percent of reading over a range of zero degrees to 600 degrees Fahrenheit or +/- 4 degrees Fahrenheit, whichever happens to be greater."
And for the second time this week, we have some 'wireless lighting' news. However, this time it is for real, since this solution uses solar power and therefore does not require any electrical wires.
"Just because the sun slips away each night doesn't mean that you can't still utilize it. When electrical wires aren't an option, you can trust solar energy to keep the lights on. Heath/Zenith motion-detecting solar lights can be placed near the dock to illuminate your boat at night and startle any suspicious strangers. Detecting motion up to 60 feet away and operating up to 14 days without recharging from direct sunlight, these lights are energy-efficient, saving an estimated 9 billion kilowatts of energy and minimizing energy pollution."
A different kind of marine electronic equipment than I normally write about, but nevertheless it will be relevant to some. I know what hassle it can be to be able to have a BBQ on board, but may be this is a solution...
"You won't need to faff around with matches or lighters as the Q features handy built-in igniters. There's even a built-in light, so you can see what you're cooking in the dark. The chic but sturdy Q utilises high grade gas jets, giving you uniform heat for perfect grilling every time. And, unlike rival grills, the Q BBQ boasts 105 square inches of non-stick, dishwasher safe cooking surface, more than enough for a flame-grilled feast."
I've covered the gadgets and electronics on board of the WallyPower before. Since many visitors to this weblog come through Google searches on the 118 WallyPower, I thought I'd post this link to a New York Times article that discusses the WallyPower and the fact that it is relatively cheap at $25 millon... And, they found a gadget on board this yacht that I missed. The pizza oven.
"Over the course of many decades and countless deprived tycoons, it has been one of humankind's most vexing challenges: how to get, quickly and comfortably, from Portofino for breakfast to Sardinia for lunch and then, should the whim strike, St.-Tropez for dinner...."
"...It splits the difference between a lightning-quick motorboat with no room for a pizza oven (which the WallyPower has) and an individually tailored Titanic that can do a party of 500 people but just 20 miles per hour...."
"...He then explained how aerodynamic design, water-jet propulsion and a special polycarbonate material worked to make the WallyPower so fleet. He apparently did not think it worth mentioning that the boat's three 5,600 horsepower engines chug down about 1,000 gallons of fuel an hour at maximum cruising speed (75 miles an hour). He talked instead about applications of military technology and sophisticated wind-tunnel tests."
Fuel cells are a hot topic in many areas, ranging from cellphones to the automotive sector. However, boating could be an industry segment where this new technology can be applied very soon. It's a very efficient way to power your boat's systems.
"The vessel can obtain its raw water where ever it is, as an onboard water maker is used to purify it, so that an electrolysis unit can split the water into hydrogen and oxygen. The hydrogen can then be used by fuel cells to power an electric propulsion motor (right) and supply the vessel's other onboard energy needs. When under sail, the electric motor functions as a generator, thus providing another renewable energy source."
Can't find any reviews of this system, but it appears to be a nice way of securing your boat and be alerted via your cellphone when something is wrong....
"The BlueRay Marine Security System supervises your boat, reporting intruders and other key events. Intruders trigger an immediate on-board siren, while all events generate detailed alarm messages direct to your mobile phone. The EB201 sends a text message to up to four mobile phones of your choice. That means there are no on-going monitoring charges."
For you liveaboards, this is the way to make sure you have fresh herbs all the time...
"Just when you think there is nothing more to invent for the kitchen you find out you are totally wrong. The Italian (where else) kitchen brand Smeg designed this inhouse, computer controlled, greenhouse for your kitchen. Which is quite handy, if you prefer fresh herbs."
A couple of weeks a go I mentioned Ascend Marine's Deep Blue Marine's Anchor Alert, a wireless anchor monitoring system. To make the anchoring experience completely wireless (except for the anchor chain...), I got a tip from Carl Midson on Coastline Technology's Windlass Radio Remote. Carl claims it's brilliant if your shorthanded on board, so check out this review in Power & Motoryacht.
"Sometimes it�s easy to inadvertently activate foredeck-mounted windlass footswitches, and cabled remotes can restrict movement around the area and often need to be passed up through a hatch, which is inconvenient at best and can be dangerous under harsh conditions. The Windlass Radio Remote allows you to control your windlass from anywhere on your boat, no matter what you�re doing and regardless of the conditions."
