About Henry Bolte
The Henry Bolte was launched in January 1966 at the NSW State Dockyard in Newcastle for the Victorian Department of Ports and Harbours and named after the Victorian premier. A 383-ton, 40.7 m firefighting tug powered by an eight-cylinder 1,500 bhp diesel, she worked mainly in Western Port. After being laid up in the mid-1980s she passed to an Eden company, and in 1988 dive operator Gary Becus bought her and the Tasman Hauler for $1 each and scuttled her about 1 August 1988, just south of Red Point. Items including her telegraph, wheel and binnacle are now in the Eden Killer Whale Museum.
The Bolte came down onto a small patch of rocky reef that tore open the starboard bow and a fuel tank and damaged the prop shroud. In 1993 McFadyen found her basically intact with a 45° list to port; the superstructure behind the bridge had already collapsed in 1992. Around 1997, age and big seas broke the wreck into four major pieces and some smaller bits. The bow is still recognisable, with a small forward hold and a bridge that can be entered, but behind the bridge the hull has ripped from keel to deck and fallen outwards. The stern, the largest section, has rolled to about 80° and stands high off the bottom; inside is a huge school of nannygai, the split gearbox, fuel tanks and a crushed muffler. At the stern are the towing winch, bollards and a steering compartment with hydraulic arms, and the prop with its shattered shroud.
Depths range from about 20 m on top of the bridge to 22 m on the stern and 25 m on the sand. It lacks the colour and intactness of the Hauler, but McFadyen found excellent fish life – including 10 or more big bastard trumpeter – and a jumble of wreckage that is fascinating to piece together.

Getting there & entry
Firefighting tug scuttled in 1988 a few hundred metres from the Tasman Hauler south of Red Point, Twofold Bay; now broken into four main pieces with a heavy list, 20–25 m.
Boat access only. From Eden (Snug Cove or Quarantine Bay ramp) it is a 10-minute run south across Twofold Bay to Red Point. The wreck is normally moored bow and stern (McFadyen).
The Tasman Hauler is a few hundred metres away, so the two are often dived on the same trip. Descend the bow line.
Entry: Giant stride from boat; descend the bow mooring
Facilities: Quarantine Bay ramp and Snug Cove, Eden; fills at Dive Eden and Merimbula Divers Lodge; Eden Killer Whale Museum holds the tug's fittings.
Weather, swell & tides
Like the Tasman Hauler, the Bolte is sheltered from southerly swell on the southern shore of Twofold Bay and can be dived in most winds, with strong easterly swell the main limitation. McFadyen found visibility averaged 10–15 m, not as good as on the Hauler. Large seas contributed to the wreck's collapse in 1997.
Best season: Year round

How the dive is usually run
Descend the bow mooring, look into the small forward hold and the bridge, then exit through the living compartments to the broken midsection. Explore the starboard compartment (toilets, corridors), cross the sand to the high stern section with its gearbox and fuel tanks, visit the steering compartment and the prop and broken shroud, then return along the keel to the bow and the upper bridge.
