First race for a while. Light air day, hovering around the 8-9 knots, but we only had 4 on board and a clean bum, so we're doing ok. We get to a longer leg, it's a broad reach, and grinning we pull out the really big lite air kite, perfect leg to pull some guys back in.
Kite is hoisted and set, and we chug along, diligently trimming and tweaking, keeping movement to a minimum, we're all dialled in and looking serious.
After about 30 mins, we're going backwards, I'm losing ground. Everything looked and felt wrong, we can't seem to trim the clew height, the kite luff is too tight and isn't behaving, so I start asking the guys to check everything.
A triumphant shout from the foredeck, they've put the aso on backwards. The tack is hanging 20 feet outside the boat, and my clew is snugly attached to the bowsprit (you could see it clearly written in BIG letters). I look at the crew, they look at me, and I here a sheepish "sorry mate, my boats symmetrical".
So much for us race hardened gurus being on the ball

.
We were so far back no-one noticed, and It was light thankfully, we quietly unclipped the clew and the tack and swapped them on the next gybe.
Funny how an asymmetrical kite can be...well.....asymmetrical.
