My Thistle

Uploading an image of my Thistle, easy enough. Above, my Thistle #1717 named "Witchcraft", built in or around the mid-60's. Earlier Thistles came with both a wooden mast and a wooden boom. If you notice, this boat still has a wooden boom. The boat was built by D&M of Ohio, Douglas and McLeod I believe it is. They also built some of the early Tartan boats.
The boat has a relatively large main and a small jib, a spinnaker too. I mostly sail solo on Kentucky Lake, rarely in any heavier than 10mph winds because of the large main. The boat weights about 600 pounds and is designed to sail its best with a crew weight of about 500 pounds. When the wind strengthens, extra weight is needed on the rail when going to windward in order to keep the boat balanced and keep it from capsizing.
Its a fun boat to sail, one of the fastest boats I have ever sailed. It was a bit tricky at first but after a couple seasons, I have discovered most of its peculiarities and am able to keep the boat right side up, very important.
Kentucky Lake is a great place to sail. There are a lot of larger sailboats on the lake, mostly cruising types. From time to time I see a few dinghy class boats, a Hobie once in a while. Back in the early '70's there were quite a few Thistles and other one-design boats, sailed mostly out of Kenlake, a very active sailing club I heard tell.
If you are into sailing and live in the Midwest, you should check out Kentucky Lake.
