A Look at Windsurfing

Karim Sarhane

Windsurfing, also known as boardsailing, is a water sport combining surfing and sailing using a craft called a sailboard to travel over water and glide over waves. The sailboard has a sail rig and a long board with fins attached to help steer it. The sail rig harnesses wind power to move the sailboard and rider. While the sailboard usually measures from six to nine feet in length, the sail rig will vary in size depending on the the windsurfer’s preferences and skills. The sport is done both recreationally and competitively. It dates back to the 1950s when Jim Drake and Hoyle Schweitzer thought of how they could combine their individual sports (surfing and sailing, respectively) into one, leading them to make several sailboard prototypes. They patented their first sailboard in 1968, and by the 1970s, Schweitzer was mass-producing them. It soon quickly spread in popularity in North America. By the late 1970s, it had spread to Europe and became as popular as in North America. In fact, today Europe is one of the leading regions in sailboard manufacturing. As a competitive sport, windsurfers compete in slalom races, regattas, and wave sailing events. In a slalom race, the windsurfer follows a winding course and must pass between pole pairs with flags. Regattas feature sailing, speedboat, and rowing races of various types. Wave sailing is a sport where the surfer rides into waves using special gear. A windsurfer may do the sport on various water bodies and conditions, including oceans, lakes, estuaries, harbors, and large rivers. Initially, windsurfers could only surf close to the shore at slow speeds. However, sailboards have advanced in design and functionality such that windsurfers can now go into deep waters. In fact, experienced windsurfers have successfully crossed the Atlantic Ocean, often reaching speeds of 40 knots using specialized sailboards. Wherever the windsurfer chooses to surf, there must be sufficient wind to drive the sailboard across the water. Importantly, the windsurfer must also follow the rules and regulations set for varying water surfaces, since some areas may be suitable for surfing but may be reserved for other activities such as swimming. Also, the individual will need to choose the right sailboard for the chosen body of water. For instance, due to stronger winds on oceans and lakes, the recommended sailboards have sturdier and heavier sails compared to those used in rivers and estuaries where the wind is not as strong. Specialized sailboards such as those used by experienced windsurfers may not be a good choice for beginners. This is because they are difficult to control due to their specific design features. There are also different windsurfing objectives. Freeriding is done mostly for recreation and is when an individual surfs just to enjoy the ride. Other objectives are often for competition. An example is focusing on speed to win a race, or maneuverability for slalom races. Another is where windsurfers ride waves, perform acrobatic skills, and perform other creative acts to display their skills. Judges award them points based on trick mastery and finesse. Windsurfing rules and regulations help avoid accidents on water. Among them, a windsurfer must maintain a three-mast distance from other surfers and swimmers. They should also never head to the waters when there are excessively strong winds or thunderstorms, and a windsurfer sailing downwind has the right of way over a surfer moving upwind. In addition, a windsurfer sailing perpendicular to the shore has the right of way over a surfer traveling parallel to the shore. Moreover, the surfer must keep the boom, the equipment that gives the sail structural support and that the individual grips onto to steer the sailboard, at shoulder height. When combined with bending the knees rather than the waist, they can then properly control the sailboard.

A Comparison of Laparoscopic and Open Surgery

Surgeons utilize two distinct methods for diverse surgical interventions: laparoscopic and open surgery. It is important for preoperative patients to understand these treatment alternatives, including the surgical processes, benefits and drawbacks, and ensuing discomfort after operation. While clinicians are the ideal experts to determine the preferred surgical approach, patients’ comprehension of the two techniques enables meaningful treatment decisions. Laparoscopic or keyhole surgery involves a small abdominal incision of less than one centimeter. Through this opening, a laparoscope (a slender instrument equipped with a high-resolution camera) is introduced to enable visualization of the body’s internal structures without the need for open surgery. Surgeons then use a magnified view on a video monitor to perform the procedure. Various surgeries can be performed laparoscopically, including abdominal procedures to treat Crohn’s disease or inflammation of the colon, rectal prolapse (where а part of the rectum sticks out), chronic constipation, and duodenal perforation (holes in the intestine). Other surgeries that can be performed laparoscopically include gallbladder procedures, gynecological surgeries, and hernia surgeries to repair weak tissues in the abdomen. Laparoscopic surgeries are characterized by their minimally invasive nature, resulting in decreased pain, blood loss, and surgical trauma. The approach also reduces postoperative complications, promotes faster wound healing, and minimizes the duration of hospital stays. Less exposure to internal organs also reduces risks for external contaminants. That being said, trocar or instrument insertion, a key process in laparoscopic surgery, may lead to abdominal wall hematoma or bleeding, as well as umbilical hernia characterized by bulging tissue around the navel region. In some cases, doctors may recommend against laparoscopic surgery due to factors such as prior surgery in the area or excessive weight, which can impede surgical access and visibility. Emergency open access may be necessary in cases of significant bleeding or infection. Additionally, individuals with certain cardiopulmonary conditions may be at a higher risk of negative reactions to compounds like carbon dioxide used during laparoscopic procedures. Open surgery may be a safer alternative in these scenarios. Open surgery, a time-honored approach to surgical procedures, involves using a scalpel to make а large incision up to 10 inches in length on the skin to reach the intended surgical area. This technique provides surgeons with access to sizeable organs and facilitates the performance of intricate procedures like heart surgery, organ transplantation, and the elimination of kidney stones. Compared to laparoscopic surgery, open surgery is good for treating conditions like large tumors, complex fractures, and spinal tumors or severe scoliosis, which minimally invasive approaches cannot address. Open surgery also affords surgeons a clearer view of the operative site, facilitating more efficient tissue and organ manipulation. That being said, due to the need for extensive incisions, this type of surgery mаy cause increased post-operative discomfort, complications, and prolonged healing periods. Medical costs depend on several variables, such as the type of procedure, the patient’s medical history, and the health care facility. Typically, laparoscopic surgery incurs а higher cost due to additional equipment expenses. However, the quick recuperation and shorter hospital stay associated with laparoscopic surgery can offset costs. In the same vein, open surgery may seem cheaper at first glance, but а prolonged hospital stay and greater likelihood of complications may ultimately increase expenses. Patients should carefully weigh various factors when choosing between laparoscopy and open surgery. Consulting a medical professional is crucial to understand the nuances of one’s unique medical situation, rather than simply relying on personal judgment or non-expert opinions. A skilled surgeon will evaluate each patient before making recommendations, empowering them to make well-informed decisions.

Laparoscopic surgery is a revolutionary surgical technique that utilizes innovative methods to deliver improved surgical outcomes. Through the insertion of short, narrow tubes known as trochars into the abdomen via small incisions, this procedure paves the way for transformative medical possibilities. Surgeons skillfully employ long and narrow instruments within these trochars to manipulate, cut, and suture tissue, granting them great precision. In stark contrast to traditional open abdominal surgery, which necessitates substantial incisions ranging from 6 to 12 inches, laparoscopic surgery embraces a more precise approach. With a mere two to four small incisions measuring half an inch or less, the benefits can be substantial. This technique allows for enhanced visualization and optimal surgical maneuvers. These incisions serve distinct purposes: one acts as an entry point for a camera, while the others accommodate the surgical instruments. A vast array of common surgeries can now be accomplished through laparoscopy, heralding a new era of medical advancement. The procedure entails using a laparoscope, a slender tube equipped with high-intensity light, and a high-resolution camera at its forefront, granting doctors a clear view of the abdominal organs. Guided by these live images projected onto a video monitor, physicians gain invaluable information without resorting to extensive incisions. Moreover, they can extract biopsy samples and perform surgical interventions, all during the same procedure. Eligibility for laparoscopic surgery hinges upon the complexity of an individual’s condition. This technique is rapidly emerging as the preferred choice for an expanding range of common operations, driven by its cost-effective nature and improved patient outcomes. Doctors now recommend laparoscopy to examine various organs, including the liver, appendix, stomach, gallbladder, pancreas, spleen, small and large intestines, and reproductive organs. Exceptional advantages associated with laparoscopic surgery include reduced bleeding, accelerated healing, and diminished pain and scarring. Unlike standard open surgery, recovery time after laparoscopic surgery can be remarkably reduced from several weeks to a few days. A vital aspect contributing to these favorable outcomes is the minimal manipulation of abdominal contents during laparoscopic procedures. Before undergoing most laparoscopic surgeries, patients typically receive general anesthesia. Adequate preparation is vital, and doctors typically advise patients to abstain from eating or drinking for approximately eight hours before the procedure to minimize the risk of anesthesia-induced nausea. In addition, it’s essential to arrange for a reliable means of transportation home considering the potential disorientation resulting from the anesthesia’s effects. Specific instructions regarding medications may also be provided by the attending physician. While laparoscopy generally carries a low-risk profile, it is important to remain vigilant for any potential complications. Although rare, instances of bleeding, infection, or organ damage may occur. If symptoms such as fevers or chills, escalating abdominal pain, redness or discoloration, bleeding, and shortness of breath persist, consult the doctor. Other signs that might warrant a doctor’s attention include swelling, bleeding, continuous nausea or vomiting, inability to urinate, or lightheadedness. There is a minor threat of organ injury during a laparoscopy, which might result in the leakage of blood or other fluids into the body if an organ is accidentally pierced. In such circumstances, additional surgical intervention is required to repair the damage and restore function. Less prevalent risks of laparoscopic surgery include issues from general anesthesia, inflammation of the abdominal wall, and the formation of blood clots that could spread to the pelvis, legs, or lungs. While these dangers are rare, it is critical to be aware of them and get proper medical assistance if any of these symptoms occur.
