The fishing Ivahahs vary in length from about forty feet to the smallest size, which is about ten; all that are of the length of twenty-five feet and upwards, of whatever sort, occasionally carry sail.  The travelling Ivahah is always double, and furnished with a small neat house about five or six feet broad, and six or seven feet long, which is fastened upon the fore-part for the convenience of the principal people, who sit in them by day, and sleep in them at night.  The fishing Ivahahs are sometimes joined together, and have a house on board; but this is not common.

Those which are shorter than five-and-twenty feet, seldom or never carry sail; and, though the stern rises about four or five feet, have a flat head, and a board that projects forward about four feet.

The Pahie is also of different sizes, from sixty to thirty feet long; but, like the Ivahah, is very narrow.  One that I measured was fifty-one feet long, and only one foot and a half wide at the top.  In the widest part, it was about three feet; and this is the general proportion.  It does not, however, widen by a gradual swell; but the sides being straight, and parallel, for a little way below the gunwale, it swells abruptly, and draws to a ridge at the bottom; so that a transverse section of it has somewhat the appearance of the mark upon cards called a Spade, the whole being much wider in proportion to its length.  These, like the largest Ivahahs, are used for fighting; but principally for long voyages.  The fighting Pahie, which is the largest, is fitted with the stage or platform, which is proportionably larger than those of the Ivahah, as their form enables them to sustain a much greater weight.  Those that are used for sailing are generally double; and the middle size are said to be the best sea-boats.  They are sometimes out a month together, going from island to island; and sometimes, as we were credibly informed, they are a fortnight or twenty days at sea, and could keep it longer if they had more stowage for provisions, and conveniences to hold fresh water.

When any of these boats carry sail single, they make use of a log of wood which is fastened to the end of two poles that lie cross the vessel, and project from six to ten feet, according to the size of the vessel, beyond its side, somewhat like what is used by the flying proa of the Ladrone Islands, and called in the account of Lord Anson’s Voyage, an Outrigger.  To this outrigger the shrouds are fastened, and it is essentially necessary in trimming the boat when it blows fresh.[20]

[Footnote 20:  For a short but sufficient notice of what is called an Outrigger, see our account of Anson’s Voyage, in vol. xi. p. 464.  The reader will find a drawing representing it in the translation of the Account of Bougainville’s Voyage.—­E.]
