An Introduction to the 500 Mb Chart

Seminar provides boaters with the 101 fundamentals involved with wind & swell wave development, propagation, & decay. Specifically: Define & illustrate what an ocean wave is & its characteristics. Discuss the dominant role that wind energy has in creating “wind waves” & what happens when “wind waves” leave their generating area as “swell waves”. A further discussion of the critical parameters of wind direction & speed, duration, & fetch as it impacts both “wind & swell wave” energy. A boater, whether cruising inside Strait of Juan De Fuca & Georgia, & even Malaspina Straits, sailing coastal Vancouver Island exposed to the North Pacific Ocean, or just blue water cruising further offshore in the North Pacific Ocean (or any other ocean), needs to understand how differing waves characteristics will impact their vessel for safe keeping. This seminar is an important prerequisite for the prepaid 2.5-hour “Understanding Weather & Cruise Decision Making Workshop”, scheduled from 3:30-6 PM. Note also the workshop is scheduled immediately after the prerequisite free seminar “An Introduction to the 500 Mb Chart” scheduled from 2:15-3:15 PM, which is also a prerequisite to this same workshop that immediately follows.
