Marks of the Channel are as follows.
You must bring the Southermost round Tower of Yarmouth to bear with the two Southermost Windmills; and so run, until you bring the said Tower open of the Mills, the breadth of the Tower; and so steer into the Northward with that Mark, which will carry you out between the two Sands.
Also there is another nearer Mark, which is there∣fore better, (but they come all to one) which is; The Wind-mill which stands on the North-west part of the Town, a little Sayls breadth to the Westward of the North-west Tower of Yarmouth, it sheweth like unto a Dove-house; this Mark will lead to the Northwards, and you shall not have less than six or seven fathom, un∣til you come to the Sea-heads, which is a Shoal that lyeth thwart between the two Sands, on which there is not above four fathom, or four fathom and a half at low-water; and when the Wind-mills come one upon another, then you enter upon the South part of the Shoal, which will continue without deepning or shoal∣ing, until Winterton-Church and the Light-house be one in the other, and then you may presently come into deeper water, and may steer away unto the North∣ward N. W. or N. W. by West, or N. W. by North, and this course shall carry you clear within the Rock that lyeth E. N. E. and W. S. W. from Winterton, on which you shall not find fifteen foot at low-water in some places.
If you be coming from the Northward, and would go into this Channel, follow this direction: To the North-west of Haseborough you shall see a low flat Church, keep that a Sayls breadth off Haseborough-Cliff, and steering directly with this Mark, will bring you in∣to the Channel before mentioned.
