Re: Help what sail to raise 1st?
I do not recall how similar the sail set-up is between 420's and FJ's. Sailing 420's, the jib is always raised first as the tension takes the load off of the front stay and pulls the mast forward. The mast is not very stable if this is not done correctly. It is much more difficult to tighten the jib halyard as much as needed if the main is raised first.
I think this procedure is much different on dinghy's because it can be done at the dock/launch while facing into the wind instead of sailing/motoring. I try to put the centerboard down first (if the boat is in water deep enough) to reduce the steps required after the sails are raised.
