cud[abbrev. of cuddy, a cabin abaft in a large ship]N.S.
n. the cosy, built-in forward part of a fishing boat.
1945  The boats that fish from Mud Island, and have to be hauled up over skids there, must sacrifice the comfort of the "cud" . . . for lightness in weight.
1960  Then I noticed an inch or two of water on the cud floor.
