Michael Henry was reportedly in a two-person boat when it capsized near Boulmer on the evening of 7 July.
The other man swam to a buoy and was picked up by coastguard, but despite a days-long search, rescuers couldn’t find Mr Henry.
Northumbria Police has now confirmed his body was located off the Blyth coast on 26 July.
It has been formally identified, and a report has been sent to the coroner.
Mr Henry’s family said he was a “keen sportsman who loved the outdoors” and a “much-loved son, brother, grandson, nephew, team-mate and friend”.
They said the teenager – from the Rothbury area – was preparing to go travelling this summer and hoping to go to university the next academic year.
Thanking emergency services, they added: “Michael will be forever in our thoughts, and we will miss him.”
