IVAHAH is the name of a canoe of the South sea islanders for short excursions to sea: it is wall-sided, flat-bottomed, and of different sizes, from 72 feet to 10: but their breadth is by no means in proportion; for those of ten feet are about a foot wide, and those of more than 70 are scarcely two. The fighting ivahah is the longest, with its head and stern considerably raised. The fishing ivahahs are from 40 feet long to 10; those of 25 feet and upwards occasionally carry fish. The travelling ivahah is always double, and furnished with a small neat house.
