Kicking off the San Francisco boating season in style, this century-old tradition brings over 100 decorated vessels sailing past Marina Green, from historic fireboats to classic yachts flying streamers. Watch the Blessing of the Fleet at 10:30 AM, then catch the "Myths and Legends" themed parade at noon: skippers go all out decorating their boats as sea monsters, mermaids, and maritime folklore come to life on the bay.
