"Trots of Cocooned and Arked Minesweepers"
Lines of ships singly or more than one abreast, moored in a bay, river or creek - also alongside a bigger ship - "(ship) on her trots" - In the RAN we say "rafted up alongside" or "raft on a (ship)" - "tie up alongside another (ship)".
To keep the interior of ships dry, Royal Navy reserve ships were covered with nylon mesh - sprayed with 8 coats of Nylon, Bitumen and Paint to make the "cocoon" airtight. Inspection ports and an entry point was then cut in the cocoon and after the ship was humidified and cathodeically protected the openings were sealed.
In the case of the Tons they first had a timber frame built over the upper deck prior to being preserved. This proceedure was used extensively by the RN in UK, Gibraltar, Malta and Singapore to preserve the Ton and Inshore Minesweepers. The process was also used by other NATO Navies. Larger ships had individual parts cocooned (such as gun turrets and radar aerials)
A ship was "arked" prior to cocooning, which meant she was fueled and watered, fully stored (dry stores), Manuals for machinery and armament, Operating Proceedures, Standing Orders & Daily Orders etc provided and only needed a crew and fresh provisions to re-enter service quickly.
