Dear Sir/ Madam,

With reference to the ongoing public inquiry into the loss of MFV Trident and the recent controversy about the availability to the public of a 1976 National Maritime Institute (NMI) report on the Trident model tests, I would be grateful if you could provide us with the following documents:

1. A good copy of the first draft of the 1976 NMI report detailing the NMI experiments on a model of the Trident and their research conclusions

2. Any subsequent minutes of meeting, discussing the document mentioned above and any possible alterations thereof.

3. A copy of the final agreed version

To ease your search, I can provide you with one of the relevant (MCA) file references: MS 92/12/09

Thank you

Yours faithfully,

Daniela Drysdale

The model tests you refer to may be those carried out at Feltham tank. If so they were comparative tests between two trawlers approx. 80 ft. in length in various wave conditions. If my memory serves me correctly, a paper was printed in one of the publications of The Royal Institution of Naval Architects. I was in attendance, by invitation, at some of those tests, having been involved in the design of one of the vessels. I hope this is of some assistance.

Best Regards,

Many thanks for your comments

Yes indeed, the Trident model tests were carried out at the Feltham tank alongside tests on another typical fishing vessel hull (included for comparison purposes) in the period 75/76.

Dr Tony Morrall was the project leader for these tests and eventually in 1979 a technical paper was drafted by NMI and cleared for publication at a RINA meeting by the DOT.

This FOI request does not concern the RINA technical paper, which is already in the public domain, it concerns the NMI report that was prepared for the Department of Trade.

The RINA paper differs from that report. Please also see

Best regards
