Hi joe:
Cute nickname

Welcome to the forum. Iv'e never heard of a Annapolis Discoverer, but O'Day licensed out the design of the Daysailer and there were many clones. This appears to be a direct clone of the the DS1, except maybe a foot longer? Poking around online, I saw some specs that list the Discoverer at 16.75' LOA, others that said 17.5'. The O'day Daysailer is 16.75, so close enough. The draft, centerboard, and mast measurements from the Discoverer were spot-on in either reference source, so I'm suspicious that the "Discoverer 18" has some marketing puffery. Anyway, I think that you will find lots of useful information here in the DS1 section of the forum.
Question - I saw a photo online of the Discoverer with a loose-footed mainsail. I think this may have been an owner modification, is yours loose-footed or a shelf-foot?
Fair winds,
Tom
