Hallo Andy
Nothing to offer, I'm afraid, except enthusiasm for the Trouper, and best wishes in your search! I have sailed my just finished Trouoer ('Cavatina') for the first time, and she is all I was hoping for - super-stable but far from dull, responsive, roomy (compared with my Storm Petrel). Mind you, my enthusiasm includes my (junk) rig for her, which is 80 sq ft on a 15 ft CF mast, so quite a tall rig and quite a bit more than either of the off-the-peg rigs (which I believe are 67 and 70 sq ft respectively, though I'm open to correction on that). I will report on my boat elsewhere on the forum, once I can organise some pics. I don't know how many Troupers there are around, but it is an underrated and very pretty little boat, and I do hope your search is successful (you could always build one?!).
