Understanding the basic trajectory of your kayak when you get into the water is an incredibly important part of enjoying your kayaking experience. Without that basic understanding you'll be nothing more than yet another random piece of flotsam being tossed around by the river.
Trajectory itself is a vital term as well as a necessary sort of math in the sport. Your trajectory is a combination of the angle at which you're facing, the speed of the kayak, and the speed or direction of the current. Y need to know where you're going and by paying close attention to these factors you'll be ready for whatever the river might throw at you.
The basics of angling and speed for maneuvering are instilled in kayakers at a very early stage. Most beginners know the basics. Getting out there into the midst of a heavy rapid can often cause you to forget or stop paying attention to the details you're trained to look for. You're going to have a trajectory no matter where you're headed in the river. What's most important is that you understand what that trajectory is and how you can affect and change it to suit your needs.
If you've ever seen a particularly threatening obstacle and merely paddled harder, you've experienced first hand the need for understanding trajectories. Instead of angling your boat properly and applying the proper amount of speed, you attempt to brute force your way away from a rock and this is not only dangerous but much less efficient. In extreme cases you might need to traverse the entire width of a rapid between rocks. The only way to accomplish this is to properly angle your boat, apply the proper speed and hope to cut off the downstream trajectory a bit.
But, keep in mind that simply changing your angle does not change the direction in which you are going. Facing past that rock does not mean you are going to go around the rock. Trajectory is a combination of all three factors and they must be combined properly to ensure they work. Imagine for example that you face your kayak upstream and start paddling. You have the angle right and you have the necessary speed (your paddling), but the current is going the opposite direction. It's negating your trajectory and forcing you back downstream.
So, the question arises then of how to establish the right trajectories while kayaking to make certain that you go in the direction you want. It's a long process of learning how to read the water and assess all of the necessary variables, plus the nature of your specific kayak. It's a matter of practice and timing. When you've practiced enough you'll soon be able to feel the difference in pull and paddling speed and the resulting trajectory you can derive from your direction.
Imagine driving your car at 60 miles an hour and trying to take a 90 degree turn without braking. It's the same basic concept. To successfully make that kind of turn you would need to start very wide and use a lot of space, utilizing the forward momentum of the car and the careful turn of the angle in the wheel. Anything more sudden will only result in a crash.
Understanding the trajectory of your kayak is a skill that comes with time, but when you finally grasp the importance of the process, you'll find that you can enjoy your outings much more because you'll spend less time trying to overcome the river and more time just enjoying the rapids.
Surfing is the only type of sport where the person relies on the wave to pick them up and for them to do tricks. Unlike body boarding and kite surfing you have to stand up fast before the wave breaks on you so you can get down the line and do your tricks on the wave.
Surfing first had started way back in Hawaii when Captain James cook was on the island. The boards they used back then were made from heavy thick wood so it made them hard to even paddle out. They were later made from other materials but not till way later when the modern short board came into play. After the short board came into the picture it changed surfing forever. Surfers could then use smaller boards but they would still float the same way as the others. Except now they could catch waves fast and do tricks that they had never done before. The boards allowed them to get down the line faster then ever so they could do new aerial tricks. The airs first started in California and places like that then other surfers started to do the same tricks so they changed surfing like never before. If you were to look at surf videos today and look at surfing videos from back in the day like the 60s and 70s you will see the difference.
Swells and waves are created from wind blowing over a long distance. That's what makes the swells travel until they hit the beaches in which we surf today. Like when you were to have a hurricane the wind would be blowing hard and fast out at sea but 50 to 100 miles inshore the waves would be pounding the shores. Hurricane surf is good because you are like guaranteed good clean offshore surf sometime or another when the hurricane gets close. Other types of swells are ground swells which just pop up over night from a low pressure or something like that. Other than that waves are made from wind.
You will see the difference between a surfer who can ride the wave and one who just can't catch the wave before it breaks. The one who can catch the wave before it breaks on them and gets in front of the barrel of the wave will be the one to show you how to surf. Like me I would drop into the face at an angle so I would gain better speed so then when I stood up I would already have a good amount of speed then I would do a few little pumps down the line then do a huge lip slide or off the lip. You are not limited to what you can do on a wave when its chest to head high surf and walling up down the beach. All you do is catch it then speed down the line and perform some sick trick that gets everyone hooting and then paddle back out.
Beach chairs are not only practical and functional, they are also colorful and fun. I've noticed through the years that a day on the beach is fun and relaxing in direct relation to the toys and goodies you bring with you. The right chairs, umbrellas, and blankets or towels are some of the things that go in this category. Think how lame it would be to try to spend the day with your kids on a beach somewhere without something to sit down on. You would get tired, hot, and irritated in no time at all. And lunch would take on a whole new level of meaning wouldn't it? It's a no-brainer that the right chairs go a long way to making the day more comfortable and enjoyable.
The first time we bought beach chairs we really skimped. They lasted all of one season and had to be tossed out. The webbing frayed and split. The colors faded. They just weren't worth keeping. Looking back I realize now that I should have brought the same attitude to purchasing those as I generally do to other things. That is, buy the very best you can afford at the time and you probably won't have to buy again anytime soon.
Thankfully, we have since purchased some beach chairs that are going to last for many years. We actually got two different types. The first type has a frame made out of redwood. This is one of my favorite natural materials because it has natural oils that make it a perfect wood for outdoor, moist environments. It grays naturally over time and looks great. These are covered in a weather resistant fabric with color fast dyes. Everyone loves these. They are comfortable and they look great. The other kind we got has an aluminum frame that is covered with an equally long-lasting color fast fabric. I like these because they have a built-in table that lifts up by the side of the chair. There is a cup holder integrated into the table and it is large enough to comfortably settle a paper plate full of summer treats.
Beach chairs alone are pretty simple. They are basically just a perch for you to plop down in. They don't really do anything other than give you a place to park it. However, it is what they allow you to do that makes them so desirable. Being able to rest comfortably while you enjoy the day makes all the difference. Whether the day at the beach turns out to be a blessing, or a curse, has a lot to do with how relaxed you can be during the day. The heat and the sand can be wonderful, but if you are stressed out, they can be pretty annoying. The right beach chairs just help. It's a subtle but critical recognition.
So do yourself, and your family, a big favor and get some quality chairs that will last for years. You'll never regret it, and everyone will thank you.
