The HI4 is essentially a scaled-up HIHP with a bigger nose. It features easy, continual rocker that allows it to turn well in the hook and support noserides both on the face and in the pocket. The board’s width up front makes walking the nose easy, while the extra width also provides more plane shape curve, making the board incredibly loose off the tail and maintains planing speed on weaker waves than the HiHp. Rounder rails in the front half gives the HI4 a lot of hold for a performance longboard, making it a user-friendly addition to your quiver that excels in waves ranging from knee-high to overhead.

CONSTRUCTION: Thunderbolt Black Technology

Thunderbolt Black Surfboards are suited to larger waves due to their more responsive carbon construction. Thunderbolt Black surfboards are hand crafter for a classic feel with enhanced response. Starting off with an EPS foam blank, a high density foam block is installed into the blank to provide a secure anchor point for the fin box. AVT flex control components are laminated to the bottom in an A shape, then a tapered groove is cut into the deck for the AVT stringer in a T shape, which is laminated onto the deck and pressed into the groove at specific depths. 

AVT flex control components are laminated to the deck, in a V shape. This combination AVT shape defines the flex, responsiveness and feel of the board creating a waistline component which creates a pivot point for tail flex, and stores the energy generated by natural flexing and twisting forces generated during a turn, which then releases through the board and fin launching the board forward. Hand laminated fiberglass layer and PVC shell lock AVT flex control components in, then is cured in a mould for precise rocker and shape. Thunderbolt black blanks are laminated in carbon making them a bit stiffer than the thunderbolt red construction. Designed in Japan, for the world.
