That actually sounds about right.
Typically the GPS's in the boats read around 3% to 5% higher. I'm sure it's a combination of the angle of the guns in comparison to the line on the boat. The fastest speeds seem to start way wide on the right side of the course, then buzz the left side of the course finish buoy directly under the guns.
But they are still not shooting directly straight on......
I think on My Way's 208, his on board GPS's were 217.
So if you lose 1000 lbs of fuel and 1000 lbs of wifes cooking utensils, clothes, water toys, and who knows what else (plus fix your alternator). You should be well over 100.....
A heck of a run though. Congrats again Class Winner....
