But, for a ship only wanting fuel and water, there is a sandy bay in the south-west corner of the sound, in which two or three streams of excellent water run into the sea over the sand, from which a ship might complete her hold in a day or two, by digging a well to collect it.
Wood may also be procured at this place, but not of so large a size, or perhaps of so good a quality as at other parts.

This bay is readily found, by its being the first to the westward of a rocky point, that projects from some remarkable bare sand hillocks, as also from its being the second sandy beach to the westward of the low flat rocky islet at the back of Seal Island.
The anchorage is good, being a bottom of sand and weeds, and is sufficiently protected from easterly winds by BREAKSEA and MICHAELMAS ISLANDS.

The anchorage between SEAL ISLAND and the first sandy beach to the westward of BALD HEAD, with the low flat rocky islet bearing west, in six or seven fathoms sand and weeds, should be preferred during the summer months; for the easterly winds then prevail, and sometimes blow strong, even as late as March; the anchorage is landlocked, excepting in the direction of East by North, the only quarter to which it is exposed, and even in that direction the angle subtending the sea horizon is not greater than ten degrees of the circle, which is of insignificant consequence.
There is no water nearer to this anchorage than in the sandy bay above mentioned, but the distance is trifling for a ship that can send boats with men enough to protect themselves while employed in filling the casks, for notwithstanding the friendly communication we have had with the inhabitants of this sound, they are not to be trusted, unless their character is different from the rest of their countrymen that we have seen.
Water is procured at Princess Royal and Oyster Harbours by digging holes at the edge of the sand under the hills; but, at the latter place, the stream that we used outside the bar affords plenty, of excellent quality, without the trouble of digging.
Over the bar of Oyster Harbour there is not more than ten and a half feet at low water, and in the neaps twelve feet at high water; but it is likely that, at spring-tides, there may be fourteen feet, or perhaps more if the wind is blowing into the harbour; but during the springs high water always takes place at night, and it would not, therefore, be prudent to attempt to pass the bar at that time.
A vessel intending to go to Oyster Harbour should anchor off the sandy beach immediately to the eastward of the entrance, that is, between the breakers off the point and the bar, in three fathoms sand, bringing the summit of Green Island, in the harbour, on with the extremity of the bushes of the west point of entrance, and the highest part of Breaksea Island in a line with the outer point of the bay: a boat should then be sent to sound the bar.

The mark for the deepest part is when the western summit of some flat-topped land, at the back of Oyster Harbour, is a little open of the rocks off the east side of the entrance.
After the bar is passed, the channel is deepest when the centre of the flat land is kept midway between the points of entrance, avoiding a spit of rocks that projects from the rocky point at the west end of the watering beach.

The strongest winds are from the westward, and therefore bower anchors should be placed to the south-west and north-west: warps and the stream cable will be sufficient to secure her from easterly winds, as the hills rise immediately over the vessel on that shore.
