asked the First Lord of the Admiralty if the date for the coming naval mobilisation and review by His Majesty at Spithead is definitely fixed for 18th July; what is the number and description of each class of vessel which will be assembled there for review; if any provision is contemplated whereby Members of both Houses of Parliament can be present at this review as in former years; if he will place in the Tea Room a chart showing the position of the ships; if he will state if the regulations which yachts, passenger vessels, and other merchant ships will have to obey during the review have yet been issued; and, if not, how soon they will be available?
Sixth-rate was the designation used by the Royal Navy for small warships mounting between 18 and 28 nine-pounder guns on a single deck, sometimes with guns on the upper works and sometimes without. Sixth-rate ships typically had a crew of about 150 and measured between 450 and 550 tons. Usually sixth-rates were small frigates. Some larger ship-rigged, flush-decked vessels, were rated, which meant they were large enough to rate a Post-Captain in command, instead of a Lieutenant or Commander.
In later years sixth-rate frigates were sometimes called "jackass frigates", as they were really not quite big enough for proper frigate duties.
