Small Plate Patch
 
Small plate patches were used for temporary repairs. The patch was 12 to 18 inches with a hole drilled in the center. A 2-inch manila line was passed through the hole and knotted. This handling line was then attached to a stanchion or other secure stable structure topside. A Sailor stood by in the damaged compartment below with a “J” or boat hook, which was used to pull the line and patch into position. The line was then tied off and used to secure the patch when it was installed. In the flooded compartment, the handling line was attached and wrapped around a stanchion or other secure stable structure. A Spanish windless was then fabricated, with a small pipe or wooden stick inserted in the lines and turned several times to tighten the line. Once tightened, the pipe or stick was secured with a small ½-inch line to prevent it from spinning out of position. This procedure created tension on the line, holding the plate patch in place from the inside.

A DC or ME 1 was in charge of small plate patch repairs, with four to five personnel required to rig and install the patch. This team was usually from repairs 1 or 3 and the unit lockers and consisted of one boatswain’s mate for rigging, two or three damage controlmen or carpenters’ mates, and one metalsmith.
