Here is another diagram:3) The centerboard is most needed when close-hauled and is not needed at all when running. At points in between, the board is needed in varying degrees, like this in general:
Close-hauled: board fully down
Beam reach: board halfway to three-quarters down
Broad reach: board one-quarter down
Run: board fully raised

It was mentioned earlier that solo sailing in dangerous. It should not have to be. I do it often, and I don't have any lines lines led aft. I also don't go out by myself under conditions that require exceptional diligence. If a situation does come upon me, I can lower the sails quickly, and start the motor. It just takes practice.
