As a tournament angler, this really jacks my jaw. Not you guys, but the attitude of my fellow T-anglers.
I know this is not your fault but if you'd get a boat hull #'s and find out what circuit they are fishing. Contact the tournament official. If he's doing his job he'll either suspend those anglers or DQ them. Every circuit I've fished has a sportsmanship clause in the rules and this sound like a violation to me.
We as tournament anglers need to share our water.
