General Notes: All Emergency War Programme. These boats are said to be an attempt by the Admiralty to combine the "Admiralty R" design with that of the Yarrow "Later Ms." They are said to be not quite so satisfactory as the Admiralty M's and R's, but good sea-boats.

To distinguish: Very long and high fo'xle, which is not not sheered or turtle-backed as in "S" boats, Charthouse built on fo'xle. Fore funnel very close to foremast. Funnels nearly equal in size with boats in davits abeam of after funnel. Quarter-deck abaft of mainmast is shorter than in "Yarrow M" boats, and has 4 inch in bandstand.

War losses: Ullysses (Doxford).

URCHIN. Some boats have platform on after pair of tubes, as above.          Photo, Topical.
