You’ll need to submit the official measurement certificate (along with a $10 fee) to register your Thistle. Here are details on how the measurement and registration process works. Download the certificate.

Only people with current Active or Family TCA memberships are allowed to skipper a Thistle in a race or regatta where Thistles are being sailed as a one-design boat. This list shows eligible skippers and the boat number associated with their membership. View the skipper eligibility list.

If you’re looking for a thorough update of what’s going on in the TCA, you’ll find it in the Bagpipe: regatta results, sailing tips, boat maintenance articles, officer updates and more. This bimonthly magazine has been a mainstay of the class since 1946. See the archives and find out more about the Bagpipe.
