• 4 + 1 fin setup (single fin with four side bites)
• Nose concave gives way to flat to convex to spiral vee/double concave
• High low rail
• Thunderbolt Black construction
• Easy, continual HIHP rocker with extra flip in last 6″ of the nose
• Rounded pin (9’1″) | Rounded square tail (9’3″)
• Beginner, Intermediate, Advanced, 1ft - 9ft waves

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 give 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.

Tolhurst was founded by surfboard shaper Billy Tolhurst from Coffs Harbour, New South Wales. Tolhurst has been shaping surfboards since 1965 when he was 12. Tolhurst became a big name in the 1990's, with Tolhurst becoming a master craftsman.
Harley Ingleby was also born in Coffs Harbour and started surfing as soon as he could walk. Tolhurst started collaborating with multiple world champion Harley Ingleby since Ingleby was a child. Tolhurst build him both long and shortboards to support his varied approach to surfing. As Harley's reputation grew, they decided to work together on the brand to produce a line of performance longboards designed by both men.
Today, the Harley Ingleby series by Billy Tolhurst is one of the most cutting-edge collections of modern longboards on the market, further bolstered by the adoption of the space-age Thunderbolt Technology innovated by Japan’s Yu Sumitomo.
