Section 2: Equipment
2.1 Surfboard Specifications
- Board type: Shortboard. Typically 5'6" to 6'6" (168–198 cm) in length, though the ISA does not enforce strict minimum or maximum dimensions. The board must be deemed safe by the Head Judge and equipment inspectors.
- Fin configuration: Three-fin (thruster) setup is standard, though quad-fin and twin-fin configurations are permitted. Fins must not have sharp or dangerous edges. Fin screws must be flush with the board surface.
- Construction: Polyurethane (PU) or expanded polystyrene (EPS) foam core with fiberglass or epoxy resin lamination. No metallic or otherwise hazardous materials on exterior surfaces.
- Leash plug: Board must have a secure leash attachment point (leash plug) near the tail.
- No motorized assistance: Boards must not contain any motorized, jet-propulsion, or hydrofoil mechanisms. The surfer must rely entirely on wave power and paddling.
- Traction pad: Rear traction pads are permitted. Wax may be applied to the deck for grip.
2.2 Leash
A leg rope (leash) is mandatory in all ISA competition. The leash connects the surfboard to the surfer's ankle or calf via a Velcro strap. The leash must be in serviceable condition with no significant fraying, and its length should be appropriate for the board size (typically 5'–7'). A broken leash during a heat requires the surfer to retrieve the board before continuing; the clock does not stop.
2.3 Competition Jersey (Rashguard)
- Color-coded lycra rashguard jerseys are provided by the organizer and must be worn at all times during the heat.
- Standard colors: Red, White, Blue, Yellow (in 4-person heats) or Red and Blue (in 2-person heats).
- The jersey must be worn as the outermost layer over any wetsuit or rashguard.
- Surfers may not alter, modify, or obscure the competition jersey.
2.4 Wetsuit and Personal Gear
- Wetsuit: Optional, dependent on water temperature. No restrictions on thickness, style, or brand. Full suits, spring suits, and vests are all permitted.
- Helmet: Optional for most conditions, but may be required by the Competition Director at reef break venues (e.g., Teahupo'o) where shallow reef poses a head injury risk.
- Sunscreen: Permitted. Reef-safe sunscreen is encouraged at environmentally sensitive venues.
- Ear plugs and nose clips: Permitted at the surfer's discretion.
2.5 Equipment Inspection
All surfboards and leashes are subject to inspection by the Equipment Inspector prior to competition. Boards deemed unsafe (sharp edges, damaged fins, protruding hardware) will not be permitted. Surfers typically prepare multiple boards and may switch boards between heats but not during a heat.
