We had trouble several years back with boards diving when running very long leads,sinkers and trolling fast...2.5mph.We switched out our releases on the front of our offshore boards to the orange OR19 release and started using a loop in the mono in that release.I watched that same video Juls mentioned to learn how to do it.Works great and stopped our diving problems.Bit of a learning curve initially and you better make sure you get the line behind the pin in the red OR 16 rear release or the board will come off.
