Thanks Rich I will definitely read those articles. The backstay turnbuckle is at its maximum right now but I don't have a gauge to measure it. There is noticeable rake so I assume I am at the best I can do for that. The weather helm for the Pearson 303 is well documented and mine seems to fit in what others describe so I will concentrate on sail shape (new sails) and learning how to read the telltales.
Again thanks so much for the help.
