Rigging a 420 (Assembling your boat): https://www.youtube.com/watch?v=6xTaFsJpwo8
Notes for rigging 420s at CBI: There are no covers on the boats. We tie 8 knots on the halyards instead of using the plastic ball. We do not raise the mainsail all the way up while the boat is still on the dock. The rudder retention lines at CBI do not work for the most part (use them if you can, but this will be limited).
