It is believed the father-of-three became separated from the eight rowers he was coaching when they launched. His motorboat and sports bag was found upturned near moored vessels by a passer-by who raised the alarm.
David Goodhew, headteacher at Latymer Upper School, described Mr Hill as a “much loved and respected member of our rowing coach team”.
He said: “This is an extremely distressing time for all at the School – in particular Michael’s colleagues in the boat club and pupil crews who make up the close-knit rowing community at Latymer Upper School.
“Our thoughts and prayers go out to his family at this terrible time.”
