DOLPHIN of the Mast, a peculiar kind of wreath, formed of plaited cordage, to be fastened occasionally round the masts, as a support to the puddening, whose use is to sustain the weight of the fore and main yards, in case the rigging, or chains, by which those yards are suspended, should be shot away in the time of battle; a circumstance which might render their failure useless at a season when their assistance is extremely necessary. See the article Puddening.
