Scuba Doo do sound doable. Primary Wench (Granny) wants to know about the availability of netting for the lifelines.
When we took our 3 year old and 7 year old (and another family 3 yr old and 6 yo), we had no netting. We did take comfortable life jackets (and swim shirts with a "collar") and the kids knew that it was just part of being on the boat/dingy. Off in the salon and a few times in cockpit.
I don't think netting is needed.
