Hi
As he died in the Bristol Channel. Bristol published newspapers might also have mentioned the incident because shipping accidents would be of interest to the shipping community on both sides of the channel.
For instance published at the time
The Bristol Mercury and Daily Post, Western Counties and South Wales Advertiser.
The Bristol Examiner, Bath Record, West of England and South Wales Advertiser.
The Bristol Gazette and Public Advertiser.
The Bristol Mirror.
Bristol Times and Bath Advocate.
Worth checking Bristol Library to see what they hold.
There look to be two possible Cardiff newspapers - one, the latter, very short lived.
Cardiff and Merthyr Guardian, Glamorgan, Monmouth, and Brecon Gazette.
The Cardiff & Merthyr Advertiser.
If the first has been microfilmed you might expect to find it more widely held than the British Library. Bridgend Library seems to indicate it is on microfilm and more widely held.

Pre 1855 newspapers covered larger areas and catered for a readership that was less interested in local events that concerned ordinary working people.
