Parasailing: The Thrill of Flying with Less Risks. (Skydiving, Parachuting).

Parachuting is not for the faint of heart. Although modern parachutes are now safer than they were decades before fear of heights will always permeate through society. Up in the air anything can still happen. When you’re free falling up in the air you only have a parachute to help you from falling to your death.

Let’s just hope that your reserve works when your parachute fails. Fortunately for those who are extra cautious, there is a recreation that will still give the opportunity that is harmless.

Most parachute skydiving involves a lot risk. Jumping off an aircraft thousands of from the ground already strikes fear. Fortunately parasailing eliminates that for a more comfortable ride. This recreational activity is usually offered at resorts for vacationers and tourists.

Harmless fun by the beach

The concept of parasailing began in the 60′s. Pierre Lamoigne unintentionally started the sport. He attached a parachute to his moving car to help his training for safe landing techniques. He used this method because it’s the easiest way to raise the pilot without having to use an aircraft. He was a parachute teacher and used this method to instruct his students.

The intention was to raise the pilot high enough and then set him free to float. However when he did not set the pilot free this contributed to the start of the sport. Colonel Michel Tournier flew behind a tractor using his parachute in 1961.

In the 70′s Mark McCulloh used the parachutes at sea. He started raising the parachutes on the shore. After that he used a motorized he designed and later on a boat to raise his parachute. Water provided safer landings so parasailing were done at sea since then. He later on created the parasail winchboat.

In 1963 the Parachute Pioneer Company began parasails. Jacques-André Istel bought the license from Pierre Lamoigne who made the first parasail to able to manufacture and sell it. Brian Gaskin also made some of the early parasails. He experimented with parachutes that were made in the 60′s and later on created the "Waterbird". It’s the first true parasail that became the template for modern ones used today. In 1975 Brain Gaskin founded "Waterbird Parakites", a company that makes parasails for commercial and recreational use in United Kingdom.

McCulloh’s parasail winchboat (which was introduced in the 80′s) along with Brian Gaskin’s "Waterbird" created a combination that made parasailing widespread.

How do parachutes Work?. (Skydiving, Parachuting).

How do parachutes Work?. (Skydiving, Parachuting).

Parachutes were very amusing when you’re a kid. They are common science projects at school. They are fairly easy to make and require only inexpensive materials. However in the real world, using a parachute while free falling has serious implications. If the parachute does not deploy at the right moment, the person can fall to their death.

Fortunately they have gone through developments and trials throughout the decades for safer landings. Understanding the principle behind a parachute is easy but understanding how parachutes work is essential. By knowing the correct sequence of deployment you’ll know that you will be able to make it to the ground in one piece.

Parachutes are packed by the owners themselves or riggers. They must be packed properly so that they will deploy correctly. It would take a lot of effort to pack a parachute. Modern designs have zero porosity which means the air can’t pass through the fabric, harder to fold.

A reserve is also packed along with the main parachute in case something goes wrong. The reserve is also packed by rigger. Is taken out and repacked again every couple of months so that it won’t get stiff.

Deployment sequence

In a normal situation the deployment sequence has steps. To start the sequence the skydiver pulls out the drogue chute. It’s inside a little pouch placed at the bottom of the container or knapsack. When the drogue inflates it pulls the bridle.

The bridle is a nylon webbing which is ten to twenty long. This in turn pulls the closing pin. The pin holds the . When the pin is pulled it gives out a small pop.

The other end of the bridle is connected to the deployment bag. The deployment bag contains the lines placed in a zig zag pattern underneath and the parachute. As the drogue and the bridle continue to pull upward, all the lines will be unfolded and stretch out. The line in turn, pulls out the risers as it continues to unfold. The risers have nylon straps that connect the lines and the parachute to the container which is carried by the skydiver.

The parachute is pulled out of the deployment bag by the tension in the lines. The wind then inflates the . Modern designs called Ram-air parachutes have sliders. They hold the lines together and prevent the from opening to quickly. If that opens it can cause a tear in the and/or hurt the skydiver.

When the parachute is completely out and opened the skydiver can grab the toggles to be able to steer the parachute towards the landing site.

Unfortunately there is still the possibility of something going wrong. A part of the main may not inflate or entirely at all, it may get tangled in the lines, rips or never comes out of the deployment bag. If any of this happens the skydiver can deploy the reserve.

You have to cut away the main first to be able to do this. A release handle can be pulled out of your shoulder straps to cut away the main .

After that, either the reserve deploys automatically due to the reserve static line. On other designs the skydiver has to pull out a second handle to release the reserve. Let’s just hope in both of these cases he reserve deploys correctly.

Take this poll! Would you jump with parachute?
