Note 52 — Chapter III

“Caution.—During strong winds, between W.S.W., round westerly, and N.N.W., the coast to the eastward of Ailly Point is dangerous to be on, and shipwrecks are of frequent occurrence; vessels therefore of every description at that period should keep a good offing, and when obliged to approach it, must do so with great caution; for although the general mass of the above banks appear to be stationary, yet great attention must be paid to the lead, and in observing the confused state of the sea in the various eddies, so as to guard against suddenly meeting with dangers which may be of recent formation. The lights for the purpose of pointing out the position of the headlands and dangers between Capes Antifer and Gris-Nez at night, are so disposed that in clear weather two can always be seen at a time, and the greater number of the harbours have one or more tide lights shown during the time the harbour can be entered.
