Understanding the Wind, 토토커뮤니티 Waves and Tides

The tide and winds can be dangerous to a beginning kayaker. Ebb and rip
tides prevent you from returning to the shore easily and wind not only
pushes you off course but also raises the height of the waves. Other
conditions create troughs that seem to trap you. Detailed charts and tables
can provide you with basic information about the area so that the safest
route may be planned, but not all water movements are accounted for on
paper.

To learn how to handle these conditions, it is 먹튀검증 best to go with an instructor
or other highly experienced paddler.

To put some of the information about the wind in perspective, the
Beaufort Wind scale rates the force of the wind into 12 categories. A
beginning paddler should not go out in wind over level 2 or 3. Level 2
breezes are measured at 4 ? 7 mph or 7 ? 11 km/h. Level 3 is 8 ? 12 mph
and 12 ? 19 km/h. Whitecaps can form at level 4 but most commonly at
level 5. A level 6 wind blowing over the ocean for two days can create waves
up to 18¹ or 5.5 meters high. Level 7 is considered near-gale force and level
12 is the minimum wind speed for a storm to be classed as a hurricane.

Off shore waves are categorized two ways. Chop is created by brief winds
blowing over a small area that create random waves. The best thing to do
in this condition is to remain calm and loose and continue to paddle
through. They make a bumpy ride but because they pop up all around,
don’t exert much force on the kayak.

Swells, on the other hand, are the large rolling waves created by wind
blowing over the ocean for great distances in the same direction. They are
affected as they approach the shore by the direction and strength of the
wind. If the wind is offshore (from land to the ocean), the waves become
steeper and break in a crash. Lee or following winds press down on the
tops of the waves so the water is just pushed off the forward face of the
wave.

With other conditions affecting the characteristics of offshore sea water
such as tides or the mouths of bays and rivers, it is important to learn
about these conditions before setting out on a trip.

Navigation and Buoys

Navigation includes having equipment to help you find your way and
knowing how to use it. A compass and map should be adequate for most
trips since people seem to follow the coast or shoreline. If you plan on
crossing a more open stretch of water where the use of visible landmarks is
limited, a compass, chart and prior examination of the area are required. It
is always a good idea to talk to someone locally who can share information
about the waters you plan to paddle.

Navigation charts show land, the main channels in the waterways and
tide and navigational marker information. The color red is always
associated with a pointed marker and green is rectangular. The simple way
to know which way to go through them is the phrase ‘red, right, returning’
which is universally meant as keeping the red markers on your right side as
you are returning to port. Other specialty markers are used in crowded
waterways, intersections or around sunken or natural obstacles.

The best way to understand navigation as well as basic seamanship is to
take a class offered by maritime organizations.
