Marine Navigation

Abstract

WHILE we may applaud Lieutenant–Commander Weems's efforts to simplify, to shorten and even to obviate the computations incidental to navigation, we cannot but regret his verbosity and his lack of lucidity. It is difficult to see for whom his book has been written. It would confuse and might well mislead a beginner. It will prove tiresome to an old hand trying to bring himself up to date, who will have to refer to the index and turn up several pages before he can arrive at a complete account of the new method and an example worked by it. A case in point is that of star altitude curves. A sample page showing some of the curves is given on p. 334, directions for use and some sort of explanation on pp. 353–57 and a worked example on p. 367.
