Spent a few hours reading old posts and trying to glean information and ideas but came to the conclusion theres nothing new !!skis ,and cats and the guy that got banned and the tunnel ideas !. AFTER some long thinking and sketching I can see merits in that concept but would like to pursue it further before moving on ! I was able to spend some time walking around and poking into an old seaplane awhile back and able to study what and how and also the inside of the hull and construction etc will have to search for the photos I took ! The step for a small hulled craft wouldn't be necessary and as was mentioned a hull with rocker could achieve the same effect that's for real !!
