BALTIMORE (AP) _ Mayor Clarence Du Burns drove the first spike into an 80-foot keel for the Pride of Baltimore II as construction got under way Sunday on a replacement for the schooner that sank in the Atlantic nearly a year ago.

The new schooner will be bigger and sturdier than the original and, unlike its predecessor, will be built to standards that will permit it to carry passengers.

The Pride of Baltimore, a replica of a Baltimore Clipper schooner and a goodwill ambassador for the city, sank May 14 about 250 miles north of Puerto Rico, claiming the lives of the captain and three crew members.

Only one of the eight crew members rescued during the sinking was among the hundreds of people on hand for Sunday's ceremony.

''It's a very uplifting time for everybody,'' said G. Peter Boudreau, a former captain of the Pride of Baltimore who is in charge of building its replacement.

A $4.5 million fund-raising drive is under way.

The Pride of Baltimore II is being built along the edge of Baltimore's Inner Harbor so that visitors to the waterfront can watch the construction, expected to take 18 months.
