US Army WT85 Protrude is a tow/tug boat built in 1943 by John Wright and Son Shipyards, in Tuncurry, Australia.

Wooden support craft were preferred over metal-hulled ships for reasons of security against mines.

On 24 July 1944 WT85 was taken out over the bar at Tuncurry by a local fishing boat, the Eldorado then handed over to US Army WT68.

In 1948 the boat was sold to the ferry operators Nicholson Bros. Harbour Transport, and named Protrude.

It is one of the last surviving craft built by John Wright and Son Shipyards.
