TJ BRAND ORIGINAL Golden Bat Bonzar

Unique channeled bottom that uses fluid dynamics to generate lift at the back.

Its most famous feature is the Bonzar Bottom (a concept borrowed from 1970s surfboards), which uses a single-to-dual concave through the tail. This channels snow to create lift and acceleration without the board feeling "loose" or "washy."

The Bonzar bottom utilizes the fluid dynamics concepts of Bernoulli's principle and the Coanda effect to create a single-double concave bottom shape. By digging two barrels into the board, the bottom speeds up the water flowing under the bottom, generating lift.

Do not hot wax the channels!
