HC Deb 28 March 1892 vol 3 c36
MR. KIMBER (Wandsworth)

I beg to ask the First Lord of the Admiralty whether his attention has been drawn to the "Submarine Sentry," recently described in the principal papers and reported upon by special representatives of some of them, as a means of giving warning to ships of the proximity of shallow waters, and so of saving life and property at sea; and, if so, whether his examination has enabled him to decide whether it might afford a means of averting the calamity and loss occasioned by the occasional stranding of Her, Majesty's ships, or to what other result has his inquiry led?

LORD G. HAMILTON

The "Submarine Sentry" has been experimented upon in some of Her Majesty's surveying ships, and seems to promise to be useful in searching for dangers; but it is not considered, in its present form, a necessary or desirable adjunct to Her Majesty's ships for the purposes of navigation.
