poor day at the office struggled in the chop was on my 95 litre most of the time managed 27.4ish knots max then dragged out the 80 litre f2 sx for a spin thats when i got some top end speed hardly suprising but was'nt happy flying over the chop felt like super power steering and my 30 cm fin lost it a few times one time resulting in a good catapult  cant wait to get it on some flat water though .
