Ed, The gentleman is using a conventional forty size trainer, not a funfly type with huge elevator authority. That airplanes setup as he described will not get off the water and if it does get bounced off by a wave it will most likely be in an uncontrolled state. The info I provided will work well and I have no need to test excessive rearward step/CG relationships for my airplanes simply because I have seen the results of just that type setup countless times over the years by others and it is seldom successful particularly on trainer or cub like airplanes.

If you care to beleive that is Bunk then fine but that is of course only just my opinion based on considerable personal experiance.
