Three boards, 6.5m & 4.7m, both rigged Big. No data card in GT31... saved to card back at home, logged track is crap. But a nice sunny warm day at Sandy Point, pleased somewhat with day, the polardiagram shows a SW- not really! Majority of high speeds with the 4.7m on the 94l Starboard, not the 6.5, work that out! The 110L was a handful, and the Fanatic- not today! The 4.7 and ^.5 rigged Big, both great to handle
