Hi Mark, I was on a broad reach in the situation I described. The spin was in the bag and the apparent wind was nearly abeam. This particular run during this 25 mile race involved heading upwind for a mile or two before bearing off on a broad reach. I was surprised by the way the boat kept working it's way upwind despite my efforts to go down. I eased the mainsheet and not the traveller because I was maintaining good boatspeed. I had another boat to use for reference. It surprised me that I had to work to get the boat down while the mainsail was properly trimmed. It made me think that the centerboards were working too efficiently for this point of sail with main only.
