How Does a Boat GPS System Work? {awesome|amazing|Great|Special}

How does a boat GPS system work? Are all GPS systems the same? Is there a separate Global Positioning System for land and water? Let’s first review how GPS units work through modern technology.

GPS satellites are operated by the U.S. Air Force. There are 24 satellites that orbit the earth twice a day. These satellites will transmit signals to ground equipment. Each satellite in orbit has an atomic clock. Every transmission reveals a satellite’s location and the time. Signals are arriving at literally the speed of light. Your individual boat GPS will rely on four different transmissions.

In order to work properly, as with any satellite technology, the device must have a clear view of the sky. That means that there will be interference in tall tunnels, forests, canyons and downtown areas.

This is good news for you who travel by sea! The sea has wide-open space, which means faster and more efficient readings with a GPS device. When you travel on the ocean or a large sea, you can get an absolute position on the globe, and get details regarding current and wind. This type of accuracy is not possible if you simply use a compass or a map.

Why buy a special boat GPS unit instead of any old GPS system made for a car?

Newer boat GPS systems are up-to-the-minute accurate and are made exclusively for sea conditions. You can find the location of your ship, the marina entrance, fishing ground and anchorage in no time. Buy a new model so you can be sure that the latest downloads are accurate.

Remember that marine boat GPS units can also track large rocks, shallow water and wreckage, just as automobiles can track traffic jams.

The majority of boat wrecks are close to land. You can depend on a new boat GPS system to guide you through turbulent river traffic. The newest models of boat GPS are so accurate that users can actually tie their system into an autopilot device and into the boat’s radar. This makes for one smooth, hands-free ride.

Marine GPS systems also have three other advantages from an ordinary GPS system.

First, they are battery operated and handheld (though models can exploit a boat’s electricity).

Second, most models are waterproof in case of accidental splashing.

Lastly, boat GPS systems have a special feature called a chart plotter. This feature allows you to see GPS information overlaid on nautical charts. Thus, you will actually be working more with the chart plotter, which is powered by the boat GPS system.

The best models are larger and have more buttons and longer external antennas.

There’s no question that a GPS will be your guide to your journey out to sea. This system is powerful enough to pick up buoys, lighthouses and even local obstructions in the water. That said, always remember to bring back up in the way of a compass and paper chart.

New technology makes boating easy!

Give Your Boat a New Lease on Life {awesome|amazing|Great|Special}

There is a small company in Florida with a most unusual and unreplicated product that has amazed hundreds of boaters who have used it, and several boat builders who include it as an option or as standard equipment on some models. It is well worth a look.

The Porta Hydraulic Transom Bracket combines the best features of two products. A simple transom bracket extends the motor off the back of the boat for stability and more room inside the boat. A simple hydraulic jack plate can raise or lower the motor a short distance (usually eight inches max) but does not offer the setback advantages of a transom bracket. With the Porta Hydraulic Transom Bracket you get both – the setback, with its advantages, and the vertical movement range – of 12″ to 24″ – much more than is offered by any hydraulic jack plate on the market. You also have a wider range to raise and lower the motor to find the “sweet spot” for control, maneuverability, and operating in very shallow water. Better yet, you can raise the motor(s) straight up and have the prop above the bottom of the boar, or raise the motors completely out of the water and tilt them over the transom. This product is in a class by itself – there is nothing else like it out there.

The company says that the Porta Bracket improves top end speed, improves engine fuel economy, allows the propulsion line to stay parallel with the boat direction, gives more space inside the boat, Other advantages include stopping electrolytic damage to the motor(s) when at the dock, and doing away with the application of anti-fouling paint on the lower unit.

The design is so versatile, with models for as many as five 300hp outboards, and with setbacks of 17 to 26 inches. This thing is way better than a simple jackplate, and way better than a fixed transom bracket.

The company wanted to make a low maintenance product with a long useful life in the heat or the cold, salt or fresh water. Careful testing for selection of the most rugged hydraulic pump led them to the Oildyne ™ 12 volt hydraulic pump with reservoir that is used on Mercruiser ™ stern drive systems. The hinge design is the key to the long-life mechanical operation of the bracket itself. It is patented and uses a material that has nylon type durability and teflon style lubricity. In over twelve years of service, no bracket has suffered a hinge failure.

The Edgewater, Florida company makes many different models that work with leading outboards of 60hp or more. To learn more about this outstanding product, visit
