I am still in skipper denial phase of learning to sail. Blame it on the boat!!!!.

From my recent sailing preformance I am no expert and perhaps I am dangerous, but if you are into spreadsheets and formulas Lester Gilbert has one which looks at many of the variables. For the techno geeks his site is useful to read.

The site is really interesting reading. It can be way over our heads in detail but he confirms that the Jib should travel slower than the main or the main should catch up to the jib on a drum winch.[:X]
