There is an active racing fleet of Ensign sailors up at Nyack, NY as well as a few other nearby locations.
Ensign Class - Ensign Fleets
There are always a few for sale:
Ensign Class - Used Boats
I also like the look of the Ensign even if the newer designs sail faster. You will also be paying more for a newer boat. Jeff is correct about the non-self bailing cockpit. The moored Ensigns all sport a canvas cockpit cover. You might have to buy a new trailer for an Ensign but you would recover the cost after a few winters of not paying winter storage fees.
Good luck.
