Still no guesses, not been many players around though
!!
Some more clues to help weed it out from the plethora of Rotax powered amphibious ultralights!!
It's American, a two-seater and is old complete or in kit form.
It offers "Spectacular pilot and passenger visibility" (that's because it's Open Cockpit
)!
It has retractable landing gear for water operation.
Removable wings (typically takes two people half an hour)
Part of its name usually refers to a small pleasure boat (sail, small motor or oars)
Good Luck
Edit: Sorry Brian, you posted while I was typing! It's not a SeaRey
