I am the tactician on the Beneteau 40.7 Wired.  This spring our captain acquired Expedition, and being a tech guy, I began learning it.  It was absolutely crucial to our finishing first in the 40.7 fleet and 4th overall out of 270 in the race.  The ability to begin analyzing weather a week before the race and plotting potential routes was phenomenal.
Even though our weather did not adhere to any of the forecasts I reviewed, the in depth exploration allowed me to analyze the race conditions from a much more knowledgeable position.  Then during the race, expedition helped me update and route the race, as well as give the crew performance targets to attempt to reach.
It was a tough Mackinac race this year, and Wired’s best has only been 5th in section, Expedition was a gamer changer for us
