The bay has a pleasant sand/shingle beach along its northern end, which turns into a sand mud beach at the south-eastern side.
.Note that the wharf has less than a metre of water at LWS.
In the southern end of the bay there is the hulk of the sailing ship, Amokura, on the beach. This hulk is privately owned and has for many years been slowly dismantled for scrap.
To the west of the hulk of the Amokura and approximately 60 meters out from the shore, is a reef of rocks at HW.
These rocks are not marked on the nautical chart. Mariners are warned to exercise caution when entering St Omer Bay by giving the area off Amokura a wide girth of greater than 60 meters.
This bay gives good holding and shelter in most winds. In N sector winds the best anchorage is near the peninsula on the northern side of the bay.
A stern line is undesirable as the wind tends to come in gusts from varying directions and can be preferable to allow the boat to move and face these gusts.
In S sector winds there is good shelter near the southern shore, between the hulk of the Amokura and the moored boats in this area.
The bottom is a combination of mud and clay and combined with the relatively shallow depth, anchors will hold extremely well.
