Shortboards

Shortboards are a class of surfboard designed for high-performance surfing. They are generally significantly shorter than traditional longboards, typically about 5'6" to 6'4" in length, with a narrower outline, thinner rails, and more rocker. These features contribute to higher speed, quicker projection, and sharper turns.

Construction commonly uses a polyurethane foam core with fiberglass cloth and polyester resin, though modern boards may use epoxy resin and lighter materials. The volume varies with rider weight, but shortboards are designed to be relatively light and highly responsive. The bottom contour often includes some concave or V shapes for lift and speed; the rails are thinner to enhance responsiveness.

Fins: the most common setup is a thruster (three fins) which provides stability and drive; other configurations include quad, twin, or single fins depending on rider preference and conditions.

Performance: Shortboards favor aggressive, vertical surfing with quick cuts and snaps. They perform best in waist to head-high waves that provide push and faceable walls. They can be less forgiving than longer boards in small or mushy waves and in choppy conditions.

History: Shortboards emerged in the 1960s as an evolution from longer boards, motivated by the desire for more maneuverability. The tri-fin thruster concept, popularized in the early 1980s, further enhanced control and release, shaping modern surfing.
