"Our condolences go to his family and friends and our thoughts are with everyone involved in this sad event."
The institute said b oth its lifeboats from Redcar were launched at about 2.15pm after the alarm was raised by a member of the public who saw a kitesurfer attempting to bring the windsurfer to shore and carry out resuscitation.
