The effects of surfboard design in wave performance
Author: SurferToday.com
Surfboard design is all about fluid dynamics, not color, look or style. When you're buying a surfboard you're choosing the plank that will suit you best. You're interested in getting a very good surfboard for your level of experience and/or for a determined type of wave.
The flow of water is the science behind surfboard shaping and manufacturing. When shapers design their models, they often know what they're doing.
There areseveral variables which take part in the "construction" of a good surfboard model. The type of blank that is used, the quality of the fiberglass and resins, the knowledge of the shaper are very important issues, but there's more.
Surfboard design also involves the outline. The overall design of the board has profound impact of the wave riding performance. A rounder template will force you to longer curves and more laid-back surf.
Width and length are very important issues. You have to choose between 18'' and 24 inches of width. Wider boards offer more fluctuation and are the perfect choice for very small fat waves. With narrower surfboards you can test you take-off skills in deep, hollow waves.
If you have trouble catching waves, you will probably need a longer surfboard. On the other hand, you'll find it harder to turn than if you were
Surfing with a shorter board.
Surfboard thickness is also relevant in wave riding performance. Normally, the thickness point is in the middle area of the surfboard but, in some cases, it can be hold through the tail and rocker.
When the thickness level is almost even, it will help balance both feet, as you change positions throughout each ride. That is to stay a well distributed surfboard thickness helps you maintain control, despite constant weight changes on the blank.
Rocker is considered the most important feature in a surfboard, by many shapers. When viewed from side, the rocker is the curve of the surfboard from tail to nose. The surfboard rocker is subdivided into nose rocker, center and tail rocker.
When it comes to analyzing surfboard rocker, there are a few logical commandments. The more rocker a surfboard has, the looser and slower it will be. Plain and flat rocker delivers faster wave performances and
Surfing maneuvers will be harder to pull - it works very well in small wave boards.
Surfboard bottom contours are also important in
Surfing. Concave and V-shaped contours have similar performances, despite opposite designs. A concave surface - or channel-type contour - will help your tail respond faster and easier to rapid turns. The Vee model helps you carve easily. A flat contour is difficult to control at high speed.
Tail designs are usually very discussed in modern surfboard shaping. Pin tail is great for big waves because there is less board in water contact and more speed is achieved.
The rounded pin tail, round tail, squash tail and rounded tail are very common because they hold the surfboard quite well in all-round surf conditions. The squash tail sits in the middle term.
Sharper edges, like the square tail, are more responsive to rad turns. Swallow tails help your paddling power and are easier to control in small waves.
Surfboard fins are part of the entire hydrodynamic performance, but are an external feature. You can learn more about the importance of fin setups (single fin, twin fin, thruster and quad), here.
John John Florence and
Courtney Conlogue have conquered the Telstra Drug Aware Pro, in clean 3–4 foot (1.5 meter) surf and perfect clear sunny skies.Florence’s performance at this event will go down as one of the most dominant in the event’s history. Florence has collected five of the top ten single wave scores and the top thee two-wave heat totals thanks to his full repertoire. Florence defeated fellow Hawaiian
Olamana Eleogram in the Final by scoring two 9-point-rides, for mixing...

Light winds and warm temperatures marked the second day of the ISAF Kiteboarding Trials, in
Santander,
Spain. The kite fleet headed over to Playa Sardinero and prepared their equipment to action. Unfortunately, everyone had to wait until 1pm in order to get enough wind o allow a course to be set. The race committee announced to firstly go for two standard windward/leeward course races to have a baseline before testing all the new course options on the agenda. Both races went underway in...

The V3 series promise a better kiteboarding experience, whether you're carving, cruising or racing. Watch the new gear in action, here. The boards have been entirely redesigned based on the feedback of existing and potential Sector riders to meet the wants and needs of the new generation of rider demanding versatility in the...
Nicole Boronat, Federico Infantino,
Yannick Anton and
Andrew Fawcett won the Fuerteventura Wave Classic 2012. Team 2 was considered the best in competition and will take the trophies of Fuerteventura back home. The last two days were hard. The crew and several riders did everything to make competition possible, but it was impossible to find any spot with wind and waves. Windsurfers drove several times along the North Track from "Corralejo" up to "Majanicho" and also checked "Glass Beach"...
Ricardo Campello is looking forward to change his preferred windsurfing discipline in the upcoming 2012 PWA World Tour season. The Brazilian windsurfer has conquered three Freestyle world titles and was runner-up twice in the Wave competition. "I was actually pretty over freestyle, I didn't enjoy competing anymore just free sailing was enough for me. My goal is to become wave world champion",
Ricardo Campello told Board Seeker Mag. Campello was born on the 16th July 1985. Playa El Yaque has...
Mounting a GoPro SurfHero camera on a bodyboard is easy. The famous fisheye surf gadget can be installed in all bodyboards, with no exceptions. The best place to mount the GoPro camera in a bodyboard is the nose. You should center it as close to the edge as possible, with the mounting pad that is sold by GoPro. The further back you go with the mounting pad, the more of your board is going to appear in the photo or video. Before applying the mounting pad to the bodyboard, it's important that...
The Box,
Margaret River,
Australia. They say this wave is only suited for bodyboarders. Surfers cannot ride it properly. They say this wave is square, fast, hollow, tricky and dangerous. The Box is everything a shore break can be, plus a super vertical approach to the concepts of taking off and dropping in. If you do not respect The Box, you might get in trouble. IBA World Tour has launched a special bodyboard documentary about this special Australian wave. Groms defend it and easily point...
