A couple found dead on a boat on the Norfolk Broads died from carbon monoxide poisoning, an inquest has been told.
The bodies of Alan Frost, 64, and Tina Wilkins, 51, from Grays, Essex, as well as a dog, were found on the vessel moored near Wroxham Island, on 9 June.
Concerns were raised after the boat had not moved for some time.
Earlier this month, Norfolk Police said the deaths were not being treated as suspicious.
The inquest was told Mr Frost was a carpenter and Ms Wilkins a housewife.
The hearing at Norfolk Coroners Court was adjourned until 30 November.
