I was delighted to learn that Baltimore, together with New York City, is being considered as the host city for a transatlantic flotilla of sailing ships, in 1992, to celebrate the 500th anniversary of Christopher Columbus' first voyage to the New World {Metro, Aug. 14}.

However, I should like to point out an error in that report: Columbus did not sail from Cadiz. Columbus sailed from Palos de Moguer, a small port some distance up the Spanish Atlantic coast from Cadiz. In those days, it would have been at least a day's journey between the two ports.

Should Baltimore be selected as the host city for the flotilla, perhaps some of the activities planned by the U.S. government, the Organization of American States, foreign embassies and other agencies in Washington that plan to commemorate Columbus' discovery of the New World could be tied into that event.

The people who make the selection should bear in mind that New York City has had more than its share of this kind of international event, including the visit of the tall ships on the occasion of the bicentennial of the independence of the United States and, more recently, the centennial celebration of the Statue of Liberty. Choosing Baltimore as the host city for the flotilla would make the event much more significant to all of us in the Washington-Baltimore area. JOSE E. VARGAS Garrett Park
