Great stuff so far!
The issue of ground crew is easily glossed over when considering a multi-day race but is so very important.
It has to be people who are willing to spend the time without the glory/fun of racing. For the Worrell this will be a 15+ day in a row commitment.
I believe every team needs at least two on the ground. In the shorter 4-5 day races some get away with one good ground crew but then every day that person has to beg for help moving the boat.
The sailors can plan to help with the ground crew work all they want, but at the end of a tough leg after a bunch of tough days in a row it won't always happen.
