Most modern shortboard surfboards feature a single to double concave bottom shape and three fins (thruster set-up) although quad and five fin set ups are also widely surfed. These boards are thinned down as much as possible, creating a board that lacks floatation and offering poor paddling ability. To the novice surfer, shortboards can be very difficult to catch waves on and unless you’re an experienced surfer, shortboards can be very difficult to ride in weak/small surf. These boards are designed for performance minded surfers and are designed for quality surf.
Shortboards need to be turned continuously to generate speed and if you posses this kind of ability, you’ll likely be able to do any type of manoeuvre you can imagine including airs, tail slides, floaters, reverses, etc. The shortboard design is definitely meant for the intermediate to advanced level surfer rather than for a beginner.
