made a deeper bigger blade for the bulbed 830 and it was awesome. made the ross go much better to windward which is unusual for that downwind flyer. i think i went up to 20% deeper. but remember the loads will increase substantially the depper you go. also made a deeper rudder on the next boat the Farr 31 but I think that was only around 15% deeper ie. 150mm.
