My problem was finding the dataset rather than opening it in Expedition.  I did finally find what I was looking for at File Share | Weather Coach (sailwx.com).  I want to recreate the historical route and wind study Chris Bedford did for the North Sails N2B 2020 seminar NEWPORT TO BERMUDA RACE PRESENTATION 2020 (northsails.com) for my boat.  Now that I have the source data, on to the next step of figuring out how to do that.
