Boats and Boating: Marine navigation - "Sailing With Wind Orientation In Mind" |
|
Home |
On the sloops where I got my basic keelboat lessons, my neck developed a crick from constantly craning back to see what the Windex on top of the mast was doing. When I straightened out my neck, my eyes would fasten on the digital readouts of the knot meter and depth finder. It seemed as though sailing involved so much time monitoring different instruments and gauges that there was no time to appreciate the ride.
What did sailors do before the invention of onboard electronics and gadgets? One thing, I learned, was that they sailed with both ears. When the sensation of the wind was equal on both ears, you were directly facing the wind.
Sounds simple and obvious. But my senses were completely dulled to the clues the environment constantly provides about its condition. Without gauges, I had no way of knowing the speed and direction of the wind and the boat, or the depth of the water and the strength of the currents in it.
My catboat Kirsten doesn't have any gauges, not even a Windex, which wouldn't work anyway because of the turbulence created by the gaff-rigged sail.
As much as today's technology aids communication and knowledge, it also atrophies our abilities to learn directly from the physical world. One of the greatest appeals of sailing is that you are dealing with the elemental forces of nature, and your ability to sail well depends upon your ability to sense and respond to changing conditions in the wind and water.
When I was younger and worked outdoors at a marina, I knew, even if I couldn't express why I knew, what kind of weather to expect with a far greater accuracy than any forecast could give. To become a good sailor and to enjoy sailing to its fullest, I needed to wake up my senses and let them learn again how to read the world around me.
It isn't easy to do that. Weather forecasts can be addictive. But forecasts are largely useless for the sheltered bays where I sail. If there's a small craft advisory for Long Island Sound, for example, I've found that doesn't necessarily mean conditions in the bays will be rough or even unpleasant. Forecasts are useful for very large areas, but not for the smaller area of the bays. To know what conditions are like in the bays, you have to be there.
But the complexity of the environment can trick you. One day, for example, the forecasts called for winds above 15 knots. Looking at the water from the dock, however, I didn't see any whitecaps which a 15-knot wind usually kicks up. I judged the wind was probably 10 knots or less. But once I had poked the boat out from the protection of the marina, it was clear the winds were as strong, or stronger, than forecast. What I had failed to take into account was that the wind and the tide were moving in the same direction, so the water was flat.
I began to read the signs. That line of small breaking waves marks a shoal. The patch of glassy water ahead indicates a place where, for some unknown reason, there is no wind. A dark patch of ripples shows the path of a gust of wind. The tilt of a buoy tells the strength of the tide.
Basic observations, but the relationships between all these forces are ultimately too complex for words, and they change too quickly for reasoning out all the meanings. This is the great challenge of sailing. Even when the course is one that has been sailed hundreds of times, it is never the same. Experience can train your senses to know what is happening most of the time, but there will always be surprises, and the learning can never be complete.
Arusha National Park is only a few Kilometers from Arusha and is a small but beautiful park set in the shadow of Mount Meru. There is a string of lakes in this park and canoeing has recently been added to the tourist activities.
One lake known as ‘Small Momela’ successful launched the canoeing safari this year. This is a great way to see the park from a new perspective. It is good to get out of your vehicle and actually get some exercise and get ‘down and personal’ with the African Bush. This chance to view the animals in their

A rigid inflatable boat is defined as a hard-hulled boat with air inflatable collars. RIB hulls are made of fiberglass, aluminum or composite materials. The soft bumpers or fenders, called ""sponsons,"" can be air tubes, or all foam systems. These boats are powered by a variety of motors and usually come from the manufacturer as a package – boat with tube, motor and trailer.
Rigid inflatable boats are more like traditional boats, with hulls supported by a rigid material. The main benefits of these boats are superior performance and easy assembly. To assemble, one simply has to inflate the tubes. However,

River rafting is a major attraction in California. The most popular California river rafting destination is the mighty American River. The American River begins in the Sierra Nevada Mountains and runs to the Sacramento River. The American River splits into three forks before it converges. The North Fork, the Middle Fork, and the South Fork each offer rafters unique adventures.
The North Fork of the American River offers the most challenging rapids on the river. It is fed by the runoff from the Sierra Nevada Mountains in the early spring when the snow melts. This runoff, mixed with the narrow canyons

Canoeing is a wonderful family vacation idea. It can be a real family-type adventure that is challenging yet not too difficult. Besides being a distinctly fun activity, it is also a form of travel. With a canoe you have the means to safely access wilderness areas that otherwise might not be possible for a family. In more touristy places you have the means to slip off across the river or lake for more private family fun.
If you have your own canoe, great. It is easily carried on your car to where you will be using it. Or you can rent

One of the ports visited on our recent Royal Caribbean cruise was Grand Cayman. This was an eagerly awaited port as I've been there before but wanted to take my girlfriend scuba diving there. We were worried that we might miss this port since the Caymans were hit pretty hard by the hurricanes and indeed, they had closed the islands off to tourist travel for part of the summer/fall.
Fortunately for us, Grand Cayman had reopened just
about two weeks prior to our cruise at the end of November.
Getting to Grand Cayman is by tender because it has a shallow
harbour. This can be a potential problem in
