12ft is iffy on a wave. we boarded the fox river and the channel was 20+ thru most but a couple spots were 10-14ft and wave was def. different in that spot. if you are regularly in 12ft that can impact the wave. it turns flatter and loses some push. if the water is regularly 12ft-ish, that's a big issue.
chuds, no disrespect taken

... but larry calls out some good info on it. if ragboy added weight, it'll need weight. he has forgotten more about setting up a boat than most of us will ever remember.
