Condesa is a 40-foot ketch, meaning she has two masts, the big one in front, the little one in back. She is a Salar 40, designed by the venerable Laurent Giles of England, and built by Essex Yacht Builders on Walasea Island, completed in November 1967. Her hull is thick fiberglass; masts and booms are aluminum. In addition to sail power, Condesa has a Perkins 4-236 diesel engine.

Condesa was built to be safe, comfortable, seaworthy, and to travel long distances. She sleeps six, with four of her berths made up at all times should anyone wish to take a nap after a few glasses of wine. Condesa has all the amenities of a small home, including a refrigerator, stove, oven, diesel cabin heater, hot water heater, inside and deck showers, towels, blankets, as well as an array of modern navigation and safety gear. She has two heads (toilets) but only the forward head is used while in the Bay. Her most prominent feature is her semi-enclosed wheelhouse, which protects guests from the elements.
