9'5 x 23 5/8 x 3VAULT 66The Vault 66 is the model that Kai was surfing when he won the US Open in 2025Heritage modelThe Vault 66 is rooted in 1960s design lineage — inspired by the original 1966 Sam Egan old mal — and built for surfers who value connection, trim, and continuous involvement.With its full rolled bottom, pinched S rails, and wide-point-back outline, the Vault 66 transitions effortlessly from rail to rail, carrying speed through flatter, fuller waves where glide and engagement are essential. The added refinements — subtle tail edge, blended nose concave, and rounded diamond tail — bring modern projection and stability without disrupting its heritage DNA.This board isn’t about sharp reactions or tight pivots. It’s about flow. About staying involved from takeoff to kick-out. About drawing longer arcs and carrying momentum through softer sections.The Vault 66 excels in fuller, slower waves where the board needs to generate and maintain its own speed.
