Product Description
A Playful Swallowtail for Young Surfers
The Ronix Sonic Fish Boy's combines surf-style turning drive with a loose release at the lip for young riders up to 80 lb.
Best For
- Playful surf-style handling: The deep swallowtail pairs bottom-turn drive with the ability to break free at the top of the wave.
- Steady tracking: A three-fin setup gives the board a more secure feel in the water.
- Kid-specific durability: Sonic construction emphasizes durability, with machined EVA traction underfoot.
- Rider fit: Ronix recommends the 3'9" size for riders up to 80 lb.
The Fish brings together a thin profile, fast rockerline and smooth rails for an all-around surf-style ride. Its swallowtail supports drive through a bottom turn while allowing a looser release at the lip, giving it a different character from a board focused mainly on added push.
The three-fin setup adds tracking to that playful shape. Durable Sonic construction and a machined EVA pad round out a design made for young riders.
