I think it would be great as well. Although I know what the green and red bouy marker mean relative to the channel, I can not make sense of it when it leaves a clear channel such as the entrance of a river. Even around the Thimble Islands, there are several bouys that I can not make out what the channel is. For me, that type of information would be great. I am sure there are a lot of me in that group.
I would surely want to attend that type of training whether it is free or not.
