Actually we don't have a T-post anymore. After the conversion to a Fleet Snorkel that went away - we have a long-wire that goes from the back of the sail aft and a floating wire, as well as several whips.
If you like, I can check our archives this Saturday - we have a couple thousand blueprints and there's a chance one of them might include something related to the T-post.
Let me know!
