We are located at Pier 39 in San Francisco Ca. at Gate "C" located behind "The Aquarium of the Bay" and "The Hard Rock Cafe" Arrive no later then 30 minutes prior to departure. Dress in layers. No one has ever complained "it's too hot" on the bay. The Bay Area has many micro-climates. For example, it may be cloudy in Napa but sunny in San Francisco. Furthermore, if it's raining in the morning it often clears up in the afternoon. Some of our best sailing days are right after the rain. If it rains in the morning the water is smoother, the winds are kinder, and the air is very clear so visibility is enhanced. Because of this, we do not allow cancellations on the day of a trip due to inclement weather. Please see http://www.bayvoyager.com for more details.
