About Hyperlite Gromcast 3.9 Wakesurf Board

Make waves with the Hyperlite Gromcast 3.9, the ultimate wakesurf board designed specifically for the younger crowd. Born from the renowned Broadcast series, this kid-friendly board combines easy surfing with a playful shape that all children will love.

The Gromcast 3.9's wide profile provides ample surface area for stability, yet it remains short and highly maneuverable, making it ideal for budding surfers keen on mastering power carves and spins. The board's versatility is further enhanced by three removable fin options, allowing for a truly personalized ride.

Constructed using Hyperlite's monocoque technique, the top and bottom fiberglass layers integrate into one, resulting in a board that withstands side impacts and resists delamination. Layered glass construction ensures the board maintains its pop, year after year, while the Biolite 3 core - Hyperlite's lightest and most durable formula - makes the Gromcast 3.9 a standard-bearer in the industry.

Shaped by legendary board designer Scott Bouchard, the Gromcast 3.9 features a squash tail shape for a snappy feel and increased hold in the wave. The molded EVA traction pad provides a cushy, comfortable platform, ensuring your young surfer's feet stay firmly planted.
