Realizing tha this thread is a bit cold, but I thought I'd chime in briefly, as we have one of the other remaining - and I believe one of the best preserved - Triangle 32's, based in Rockland Maine
"Sionna" is hull #11. The hull was built in 1963 by Grampian in Canada
, and finished out in Rochester NY by Triangle yachts.
Other comments are pretty accurate - two tandem (stainless steel) centerboards, the primary is centered and improves her pointing significantly when close to the wind
, the aft is seldom used but does settle her down from the usual corkscrew motion when running downwind. If you forget it's down she WILL NOT tack!
Very comfortable, slightly under-rigged as you would expect for a boat with her relatively light ballast/weight ratio, and built like a brick outhouse, with very nice wood furniture and double cabins.
I'd say an excellent coastal cruiser (we'll be taking her to Florida
in Fall 2016) winter and a passable blue-water boat IF properly equipped and sailed within her limitations, but ocean crossings was not her primary mission as designed.
For what it's worth - we love her!
