"Floater" is a relative term I have found. I consider Pat Tritle's planes (most of them) floaters. They come in around 6-8oz/sqft wing loading. Peter's are usually 10-12 oz/sqft. I have flown several planes in the 20oz/sqft range.
Of all, Peter's are the most 'flexible' when it comes to flying in wind and turbulence. Slower flying, yet about to handle the 'normal' breezes.
But, the slimers at the local field consider my 8lb 60" WACO YMF a 'floater'. Heck, if it is less than 80" span and 30lb they consider it a 'floater'.
I guess if it flies slower than most of your planes it is a floater.
