In this 3 hour program Peter Isler delves into two of Expedition’s most valuable and powerful tools: Expedition’s Weather and Route Optimization features.
The course will be recorded and attendees will have full access to the recording (online, not downloadable) through the end of the year.
The Weather portion shows how to download and display weather forecast GRIBs. Peter enumerates the various sources of Wind/ Weather GRIB files (and also current and tide info) and the details of how to download the files and display them in Expedition. He also provides criteria to help you evaluate the likely accuracy of the files and shows how to compare information from the various sources.
We’ve got the forecast. Now what? Once you have a forecast, a polar file, a start time and a course, Expedition can calculate your the optimum route. Peter takes you through the details of that process and highlights common errors. In addition, you’ll learn how to differentiate between routes with narrow optimum choices and those that offer wider course options. He also shows how to compare routes built from different GRIBs, how to evaluate their likely accuracy, and how to update mid-race.
Gotta Have It
This module is absolutely essential for offshore racers and passage-making cruisers. For distance racing and passage cruising effective Weather Routing is what it is all about. (For passage-making Peter details how Expedition allows you to route across a span of departure times and then optimize for the best departure time. Way cool.) For Buoy Racers the weather info and GRIB display features provide critical reinforcement to real-time observations and allow for more confident strategic planning.
As with all the North U Expedition Webinars, Peter Isler is a key ingredient. An outstanding racer, and world-class navigator, Peter is also a gifted instructor. Don’t go to sea without these skills.
