 Painstakingly restored in the 1950s by Harold Sommer, captain of the last wooden tugboat on San Francisco Bay, "Freda" became a fixture in the local Master Mariner fleet regattas, but has since suffered from years of deterioration.Originally built with rock elm frames, Douglas fir decks, black elm and fir hanging knees, fir planks, and lignum vitae deadeyes, "Freda" embodies the creativity and self-reliance of San Francisco Bay wooden boat builders.
