In the Tybee, you can have help from your ground crew during any leg without being disqualified. If you break a rudder, they can bring you a new one and help install it on the beach. If anyone out there decides they want to do it, I've got many spare spares for I20 that could be bought pretty cheaply. The best spares are:
spinnaker
dagger
rudder
spin pole <---just ask JC!
all rudder parts (gudgeons,castings, springs, everything!)
tiller stick
crew <--always have spare crew
Corona
Limes
Mexican food
