You can use a kayak in SCBBBC.
"1. All SCBBBC tournament fishing must be conducted from an inflatable float tube or kickboat (pontoon style) and kayaks. Tournament Anglers may not fish outside of their boats for any reason. Anglers must be floating in their boats while fishing. Anglers may not accept assistance from boats or other anglers to move about the body of water. Only fins worn on feet and oars may power float tubes, kickboats and kayaks. The use of motors and sails and any mechanical propulsion is prohibited. Violation of this rule will result in Tournament disqualification."
One thing in regards to the current rule, is that I wish that Hobie fin style propulsion would be allowed. There is always going to be the pros and cons of using a kayak, but speaking personally as someone who can not use oars at the moment due to a shoulder injury, it would be nice to be able to fish again.
I as well would love to see the peddle style Kayaks added some day. I have only recovered about 70% of my strength back in my shoulder since my surgery and I just can't row with my right arm. I just got a Hobie Pro Angler and it has been amazing to be back on the water. Miss fishing with you all and hope you are doing well.
