Tenerife, though considerably without the tropic, is so nearly within the limits of the tradewind that navigators generally steer to it from the eastward. The road of Santa Cruz lies on the east side of the island, at the end of a range of craggy hills, barren and very lofty, along with you sail west by south by compass into the road, with a sea unfathomable until near the shore. The anchoring ground may be accounted from fifty fathoms to twenty, or even fifteen. The bank is very steep and gives but little time to sound; for which reason it should be done effectually with a heavy lead, or a ship will be too near in before a stranger is aware of it: he will likewise too soon expect to find bottom, owing to the great deception of the adjacent high land. To obviate these difficulties it is necessary to observe that while a town which lies some distance to the southward of Santa Cruz is open with the castle on the south part of the road, though you may appear near to the shore, there is no anchorage; but after it is shut entirely in you get on the bank. The church bearing west or west by south and the south point of the road south-west half south to south-west by west is a good situation for anchoring: the depth about twenty-five fathoms. The distance from the shore will be three quarters of a mile; and the southernmost land that can be seen then will be a half or quarter point of the compass farther out than the south point of the road. The bottom is black soft mud, with some patches of rocks; for which reason vessels that lie here any length of time buoy their cables. This precaution, besides being useful in that particular, they think makes them ride more easy when there is much sea setting into the road, which, with the wind any way to the southward of east or at south-west, must be very considerable; it is therefore usual to moor with four anchors, though more than two are scarce ever of use. Mooring is however advisable if a ship is only to remain twenty-four hours, and the tighter the better, that the cables may keep clear of the ground. The landing on the beach is generally impracticable with our own boats, at least without great risk; but there is a very fine pier on which people may land without difficulty if there is not much swell in the road. To this pier the water is conveyed by pipes for the use of shipping, and for which all merchant-ships pay.
