Spot Guide › United States › California › Treasure Island east side → Berkeley Pier downwind route
California, United States · 37.8490, -122.3350
Best wind
Strong west-sector bay wind; reported around 25 mph at the start
Season
Condition-dependent
Water
Short-fetch San Francisco Bay wind swell, about 1–2 ft in the report
Experience
Advanced tidal-bay foiler with support boat or reliable self-start
Hazards
Strong tide, rapidly fading wind, short fetch and dependence on a supported start. Ebb was considered better for standing waves than the reported flood; the forum does not provide a traffic or rescue plan.
Parking & access
The documented attempt used a support boat. Do not infer public launch or landing rights; establish legal Treasure Island water access, Berkeley recovery and vessel logistics in advance.
“Progression Project forum first-hand report documents a roughly 3.5-mile route from the east side of Treasure Island to Berkeley Pier. The rider used boat assistance to start in one-to-two-foot bay wind swell; the start measured about 25 mph before wind weakened along the short-fetch course.”
