Swim Trip Jump Times

Slack water in the Bay is set by the current, not by tide height. Pick a trip and a date, and we'll recommend a daylight jump time from NOAA current predictions at the stations that govern each route. Prices are per boat. Once you have a date, book the swim online from its page, or send Captain Molly your plan with the Ask Molly button.
