The whale-boat, evolved from the needs of this fishery, is one of the most perfect pieces of marine architecture afloat--a true adaptation of means to an end. It is clinker-built, about 27 feet long, by 6 feet beam, with a depth of about 2 feet 6 inches; sharp at both ends and clean-sided as a mackerel. Each boat carried five oarsmen, who wielded oars of from nine to sixteen feet in length, while the mate steers with a prodigious oar ten feet long. The bow oarsman is the harpooner, but when he has made fast to the whale he goes aft and takes the mate's place at the steering oar, while the latter goes forward with the lances to deal the final murderous strokes. This curious and dangerous change of position in the boat, often with a heavy sea running, and with a 100-ton whale tugging at the tug-line seems to have grown out of nothing more sensible than the insistence of mates on recognition of their rank. But a whale-boat is not the only place where a spill is threatened because some one in power insists on doing something at once useless and dangerous. The whale-boat also carried a stout mast, rigging two sprit sails. The mast was instantly unshipped when the whale was struck. The American boats also carried centerboards, lifting into a framework extending through the center of the craft, but the English whalemen omitted these appendages. A rudder was hung over the side, for use in emergencies. Into this boat were packed, with the utmost care and system, two line-tubs, each holding from 100 to 200 fathoms of fine manila rope, one and one-half inches round, and of a texture like yellow silk; three harpoons, wood and iron, measuring about eight feet over all, and weighing about ten pounds; three lances of the finest steel, with wooden handles, in all about eight feet long; a keg of drinking water and one of biscuits; a bucket and piggin for bailing, a small spade, knives, axes, and a shoulder bomb-gun. It can be understood easily that six men, maneuvering in so crowded a boat, with a huge whale flouncing about within a few feet, a line whizzing down the center, to be caught in which meant instant death, and the sea often running high, had need to keep their wits about them.
