Don -- I have the Sail Trim Chart and have found it very informative. I am trying to find a creative way to obtain funding approval for the User's Guide from my wife 
I am interested in your comments on any special tricks to trimming sails on Hunter's B&R rig. They have no backstay, no cunningham, full batten main with a large roach and a very small jib. I have a H29.5 which I use for day sailing mostly. I am not involved in racing, although my primary joy from sailing is getting her to move as fast and efficiently as possible under present conditions. The only tale tells on my main are ribbons located along the leech. If critical as trim indicators, are mainsail luff tale tells difficult to install and where should they be located? Thanks in advance.
