2 x 75s holy shit those things are fast downwind they go like a train, i did antigua sail week and did a day sail on one ( i forget the name but when we put the kite up the thing took off like a scolded cat.we did 5 crossings across the pond in the 57 great fun . All the very best of luck to you M8 hope you dont get too many tosser charter partys, as they can be really hard work,mind you your job will be 24/7 but ENJOY. regards Bob
