As in Te Awaiti, the whole of this bay is shallow and only about three meters deep. The bottom is a mixture of malodorous (foul-smelling) sand and mud that grips anchors like glue.
The bay is an excellent anchorage in winter months. During summer months, green lettuce seaweed will clog anchors. This bay is sheltered from all except E to SE winds and misses most of the ferry wash.
There is little depth of water past the wharf at LW.
At the end of the wharf there is two meters of water. The bay is good holding but exposed to most winds.
A boat builder lives in Jacksons Bay but now does not have a slipway.
