OSLO, Norway (AP) — Norway's royal household says the king's brother-in-law Johan Martin Ferner, who was part of the sailing team that won silver at the 1952 Summer Olympics in Helsinki, has died. He was 87.

In a statement, King Harald V announced "with great sadness" that Ferner died Saturday. The statement did not give a cause of death.

Ferner was a commoner who married Harald's sister Princess Astrid in 1961. They had five children.

He was part of a five-man team that grabbed silver in the 6-meter class that was part of the Olympic sailing program from 1908-1952.
