When you've got it right with "boats" Berny you know, and until other people experience just how "their" ideas work (or don't) There will always be the "armchair" experts who will try to take a rise out of you, with out ever putting in the required effort to actually test their own "theories". There is a saying that "the sea is an element that tolerates no compromise" If it works it's fun, if it's wrong then you suffer the risk of death.
