Beyond the conditions, the Iwa foil seemed to be a champ in the higher wind conditions. I didn't feel the cavitation (???) or 'burping' that I did using the Maliko 200 at similar speeds.
I was able to get a bunch of long rides - pretty much runs from one end of the race track to the other. There were several runs where I didn't even feel the sail pressure (sail was fully sheeted out).
All was not honky-dory... a few runs had porpoising, and one of those runs had the mast striking the board nose. I got a crack on the top deck of the nose and a small blow out on the front rail. Not a bad ding, but it'll be a pain to fix. I'm going to modify the nose to prevent this from happening again... But looks like I won't be windsurfing this setup for a couple of weeks. La and the kids were at the beach and La got some great pictures of me flying the foil. It is great learning something new!
