4.7 is my favorite sail size. Yes it is yes it is yes it is. You can have your 4.2 days (I'll take those too, actually, and everything else!) I like 4.7 best.
That's what we got at Sebonac yesterday. Scott on his new 75 liter, plus the Wolf, Jonathan, Kurt, Rich, Jan and Bruce, Christian and Frank under the sun (blinding sun on starboard) in 25 gusting to 35 NW. NW? Yeah we shoulda been at Meschutt, where it might have been a teensy bit better, but still, Sebonac went off! Towards the end of the afternoon the wind came up big time (4.2? 4.0?)...I didn't have the will to rerig, and thought about sailing overpowered, until Scott can flying through the inside, as fast as I've ever seen anyone sail, barely holding it together as he flew to the east side beach. "That is some sailing" Jonathan said. I thought I'd explode in that much wind, and so called it a day.*
*also I was getting cold in my 4/3 plus neoprene shirt. Time to switch to the drysuit.
