Another nice day for a sail, good to see Blackjack back on the water - in her usual place! Twinfinity's CB Rating has now been updated as she has completed 4 races. The original guesstimate was accurate (for a change) and hasn't made any difference to the results on back calculation. Surprisingly a lot of boats were singlehanded and one skipper came back with a few extra lumps on his head after losing the argument with his boom!
The results are in the file below .
