I tried out the first of the sail floats on Friday and it was a complete success. I capsized and was able to stand on the mast head and still not invert the boat. There was no noticeable loss in performance on any point of sail.
Unless you are very confident that you can right an inverted catamaran unaided you should get the floats added to the top of your sail before the start of the season.
The floats can be removed by untying string.
They are class legal at Shanklin.
They cost £84 from Sailcare in Cowes Yacht Haven - http://sailcare.co.uk/ - 01983 248589.
