Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1885 edition. Excerpt: ...during the first 4 hours, and with great rapidity. During the last 2 hours a weaker current set East, N.E., and North. The current of ebb runs S.W. in the Fromveur Channel; but during springs it is sometimes met by the first of flood and deflected to N.N.W. and North outside the island, before low water. There is more danger with a weather ebb tide than with a weather flood in the Fromveur. In the Chenal Dd Four the tidal currents run knots at springs; but with much lees velocity at neaps, although abreast of La Grande Vinotriere they still run 3 knots. The set"of the flood is N.N.W., that of ebb S.S.E. Off Kermorvan Point the ebb is first felt at the time of high water at Brest; at Les PIStresses half an hour later; between La Grande Vinotriere and Beniguet Island it sets towards and on Les Bossemen during the first 2 hours, --flowing to eastward of them afterwards. The current of flood is first felt off Kermorvan Penineula one hour before the time of low water at Brest; at Les Pl&tresses one hour after; at Le Four hours after; and at La Helle 2 hours after. Eastward Of Benigdet Island, and also in the vicinity of Les Chambres, the flood sets N.E., and the ebb S.W.; both generally strong. Through the Goulet the tidal currents run strongly in and out, attaining a velocity of 3 knots at springs. In The Iroise the tidal currents when undisturbed by extraneous causes are quite regular. In the centre of the space they have not much apparent strength, but their velocity increases on approaching the opening of the Ushant Channels and the Raz de Sein. Their varying force in consequence of the influence of winds, renders the navigation of the Iroise difficult in thick weather, and under such circumstances it is advisable to anchor when...show more
