What we have learned by sailing and racing the sixteen (now 27 as of last weekend) Oz Geese in the Philippines. Some money saving simplifications and some tweaks that will give a lot more performance to most lug rigged (and other boats). There is nothing unusual in these methods, just a translation of regular racing practice in more conventional boats. Don’t scoff – you can say “I’m a cruiser” – but there are times when everyone wants or needs to get upwind 10 or 20 percent faster.
