KBF and B.A.S.S accepts all Ketch boards including the Ketch Karbonate.
The Hobie Bass Open Series accepts ALL metal Ketch boards. No other board is permitted.
Most local and regional series either accept Ketch Boards or only accept Ketch Boards, but please check with your trail to ensure you’re within the rules.
Some trails for example require a metal board only meaning you cannot use the Ketch Karbonate board for their series.
