My wife and I have owned one since '95. She was launched Oct '90, but not completed by Biscay Yachts/Falmouth Boat Construction so some things may differ.
Sloops and ketches were available, with, I suspect, ketches just in the majority. Falmouth Boat Construction built all the early ones, late ones were fitted out by different yards and a few home completions. They are a stiff, seaworthy boat, although not a big 36 footer by modern standards - no aft cabin for example. Large tanks and good sea-berths make for comfortable extended cruising and the semi-flush deck layout means that there is plenty of space forward. We inflate our Avon Redcrest flat on the foredeck - none of this balancing on coachroof and guardrails! Performance-wise, surprisingly quick on a reach as the long overhangs immerse, but not as closewinded as a modern fin leeled sloop. To give an idea, we usually stay with Contessas and Sadlers to windward, and then leave them on a reach. They are of course, shorter on the waterline. The Rustler 36 is much the same performance as the Biscay if you're familiar with that class. Ours is a ketch with the usual pros and cons. More rigging, more bits to go wrong and replace and greater drag to overcome to windward. On the plus side, the rigging makes for a wonderfully secure cockpit and the mizzen staysail is a real secret weapon - easy to handle, sets in light airs and pulls like a train. A block on the mizzen boom makes it easy to recover heavy kit such as diving cylinders. The mizzen and storm jib combine to make a snug heavy weather rig too. Most (but not all) interiors sport a pilot berth, at least one has a dinette arrangement (the BR dining car layout - owners words, not mine!) and there are subtle differences in galleys and heads. I've been on 8 and not yet seen 2 the same. Basic dimensions are 35' 11" LOA, 10' 9" beam, 27ft LWL, Didplacement approx 8-8.5 tons in cruising trim with full tanks. Let me know if you want to know more - you could always contact YM Second Opinion who (should!) have my number, or e-mail direct. Where in the country are you, I may know one you could look at. Regards.
