Tides and Currents and the Inside Passage

Sign up or log in to save this to your schedule and see who's attending!

A good understanding of the Tides and Currents can mean the difference between a smooth ride and a rough ride for a captain and crew. The Inside Passage has a unique water system where the tides power strong currents around the islands and in many of the key passes. In this session, we will begin with an understanding of how the lunar cycles create water movement and the various stages of the tidal cycles - in short, the conditions for slack can mean different things based on the lunar cycle, the winds and even the geography. The course will explore the many gates that are keys points in travel and understand the key concepts of vertical movement (tides) and horizontal movement (current) of water. Understanding local knowledge and the resources available to plot times of slack and understanding the tidal range and current speed in a given day and hour are emphasized. Next, the impact of wind is reviewed. Wind against wave can lead to ugly and uncomfortable seas. A brief understanding of the weather reports will allow you to avoid uncomfortable seas, where waiting an hour or two can make all the difference and a comfortable sea state for safe passage.
