two of my mates were out on a 4m and 5m kites,wind gusts were up to 48 kts on the windmeter,no jumping just riding and hanging on, another time we were out on 5.5m kite in the morning and in the afternoon there were 2 guys out on 3.5m kites and surfboards,not really that much fun,they were able to ride in the flat water{well sort off} but as soon as they were in the waves they fell,wind is too gusty and volitile,think a 2m-4m kite might be the go for 59 kts ,might help if your being kiting for 10 years and are a little crazy

,really strong wind is no fun and is SO dangerous
