DONEY. The doney of the Coromandel coast is about 70 feet long, 20 feet
broad, and 12 feet deep; with a flat bottom or keel part, which at the
broadest place is 7 feet, and diminishes to 10 inches in the siding of
the stem and stern-post. The fore and after bodies are similar in form
from midships. Their light draught of water is about 4 feet, and when
loaded about 9 feet. These unshapely vessels in the fine season trade
from Madras and Ceylon, and many of them to the Gulf of Manar, as the
water is shoal between Ceylon and the southern part of the continent.
They have only one mast, and are navigated by the natives in the rudest
way; their means for finding the latitude being a little square board,
with a string fast to the centre, at the other end of which are certain
knots. The upper edge of the board is held by one hand so as to touch
the north star, and the lower edge the horizon. Then the string is
brought with the other hand to touch the tip of the nose, and the knot
which comes in contact with the tip of the nose tells the latitude.
