Starting at Ryde, Eric took 5 hours 2 minutes to complete the journey, which took him past Yarmouth, Ventnor and Appley.
This marathon round the Isle of Wight journey had the goal to raise funds for Macmillan Cancer Support.
Eric, who works at GKN in East Cowes, battled blustery conditions to complete the 55-mile challenge has raised almost £4,000 for the charity.
He said: “Apart from a near wipe-out near The Needles, which ended up with my kite inverted in the sky and wasted about 20 minutes, it went perfectly.
“It was pretty rough though. One of the support crew was thrown from his RIB via the wind shield after hitting a big wave but luckily no serious bodily harm was incurred.
Congrats to Eric Diamond and to the Macmillan Cancer Support
