I have a new hunter 27 and am trying to figure out how to set the cars for the jib. I set them to the same "hole" and when on a port tack the sail does not develop the nice shape and power I get on the starboard tack. I was thinking I should measure from the chainplate to the start of the track to determine how far they are off and then use that for a reference. That said I am also confused as to the direction to move the car vs wind speed. Having read both. My final problem is that I have no telltails on the end of my main and have an in-mast furling system. Is it worth putting them on? How do I do it without climbing the mast? If I am not interested in racing and just relaxing cruises with my wife is it all that important in the first place?Thanks for the help.
