Goodsteel/151. I have # 363 and my sail is the exact same color scheme, but in a different order. That smells original, but he logo and its placement are completely different on my mainsail, plus my sail is numbered 363 (matching the hull), which leads me to believe that yours is a replacement...
Ok, one more post by me for an "action shot." Note a couple things on this. One, the skipper is my buddy (on his second time sailing my boat). Two, note the FISH jumping in the foreground. Three, seconds AFTER this shot, we got a gust, stood her on her beam, filled the cockpit with water, I dumped the jib (note I am playing the jib as he sails), and we flattened her and took off again! Thankfully he LOVED it.
