Here is some sail for thought. This is the sixty-six foot AAPT entrant from the 2004 Sydney to Hobart race skippered by Sean Langman showing off their kite spinnaker. Kites were disallowed the following year but in 2004 they were legal. AAPT placed 2nd in 2004 into Hobart in 04 from 3rd the year before. This whopping sail/kite is 420sqm (4,570 sqft!!!). Remember thats a 66ft long boat. Just something to keep the brain juices flowing for everyone out there building a boat. Link: 12-5-07 AAPT kite Spinnaker
