In 1987 the Australian National Maritime Museum purchased a set of original shipyard plans produced by the Scottish marine engineering and shipbuilding company Gourlay Brothers & Co. in Dundee. Like the best of discoveries, it seems the plans were destined for the rubbish but were saved at the eleventh hour. Together the plans represent images of early Australian cargo vessels, as well as a wide range of Australian shipowners and a long tradition in ship construction procedures.

April Fool’s Day – The wind has been steadily increasing overnight and some of the team – including Frits and Lee – have abandoned Hellraiser 2 to seek more comfortable berths on board the much larger SWII which does not bounce around so much in the increasing swell.
Plans for the day are much the same as yesterday, with the exception that the team will be joined by Steve and Sparra in Hellraiser 2 which – because we are operating more than eight miles away from the main vessel SWII – will act as a temporary rest stop for the teams working out of the smaller dive tenders.
Four teams on and in the water today – Frits and John ‘magging’ in Maggie; Gil, Greg, Lee and Freddy diving anomalies in Caribe; Xanthe, Jacqui, Andrew, Rick, Glen and I ‘magging’ and diving in the Hydro-sport; and Sparra, Steve and Grant on Hellraiser 2.

After a somewhat late night for the expedition team members and crew who had been waiting for the arrival of Hellraiser 2, the team members got together early the next morning to discuss the practicalities of working the ‘end of flood tide’ on the wrecksite so Xanthe could get a complete photomosaic of the site.
We decided to send a small team of divers, including Xanthe, Greg, Gil and Andrew, over to the site just before the ‘end of flood’ at 0700 so that Xanthe would have enough water depth to complete the photomosaic. Just in case, Freddy and Kieran would act as stand-by divers so that the in-water divers could be pulled out of the water if the ebb-tide came in earlier than expected.
Luckily conditions on site were perfect with the strong south-easterly (wind) holding up the ebbing tide long enough for the photomosaic to be completed without incident.
In the afternoon we planned for Frits and John to mag the northern part of the lagoon, have Andrew and Grant record the features of the carronades (cannon) on site, have Gil and Greg record the dimensions of all the various bits on the anchor chain, and Jacqui and I would record the knee and bilge pump dimensions. Unfortunately and unexpectedly the tides refused to cooperate – although for the last couple of days, the tides were behaving relatively normally with gaps of approximately 6 hours between High and Low tide – today the ebb tide was more prolonged, possible due to the effect of the New Moon. This meant the dive tender and Maggie (the shallow drafted magnetometer boat) were unable to get over the western edge of the reef and onto the wreck site.
After waiting for three hours – and noticing no discernible difference in the level of the water over the reef – the team called the dive and returned to Silentworld II.
Tuesday 26 March
This morning the weather conditions appeared to be improving on yesterday’s so we sent off four teams to work on the Ferguson site.
Team One consisting of Frits and John dove on a series of magnetic anomalies off the south western side of Ferguson Reef, Gil and Greg in Team Two measured up an anchor at the northern part of the site, Peter and Jacqui in Team Three measured a ‘flat’ anchor and Grant and Andrew in Team Four measured an anchor in the surf zone. Whilst all this was going on Xanthe took photographs of the work in progress and I monitored the work from the surface whilst taking part in an open classroom discussion via telephone through the DART virtual excursion program of the NSW Department of Education.
As the teams returned from the wrecksite the whole area was struck by a series of rain squalls drenching everyone – well at least it saved us the job of washing the dive gear.
After lunch, sea conditions appeared to have quietened down once again and in almost perfect conditions we set off to dive on the site. Gil, Greg and I went to measure the length of a stud link anchor chain that was attached to a ‘picked in’ anchor. Peter and Jacqui jumped in to measure up the various iron knees, assisted by Andrew, John and Frits armed with metal detectors they commenced a non-disturbance metal detector survey of the site to find out ‘what lies beneath’.

As the expedition winds down for 2009 the weather has been winding up – the wind and the seas have been gradually increasing over the last three days. Whilst its still possible to dive on Endeavour Reef an expected wind shift to the south and east will making diving on the HMB Endeavour stranding site very difficult.
The first dive teams were in the water quite early this morning trying to finish off the Endeavour Reef research prior to the wind shift.
Nigel had tracked down archival information on the early salvage work on the site. This information indicated that the early salvor’s had recovered most of the stone ballast from an area 26 meters at 080 degrees from the tripod. The records also indicated that most of the iron kentledge was recovered from an area 28 meters at 105 degrees from the tripod.
The stone ballast team consisting of Peter, Nigel, Lee and Warren and the kentledge ballast team, consisting of Xanthe, Ed, Grant and myself located the railway iron tripod and ran out tapes on the designated bearings. Luckily for us the salvor’s information proved accurate and the two teams quickly located the areas.
Visual surveys of the two areas indicated that the reef areas still showed signs of the explosives with a large depression 10 meters in diameter and 1 meter deep marking the area where the kentledge had been recovered. This depression, devoid of any coral, was stripped back to bare coral rock. A metal detector survey of this area produced no magnetic anomalies however Ed Slaughter did locate a significant anomaly about 14 meters away from the tripod.
The stone ballast team did not see evidence of blasting but did not locate several other ballast stones and more lead sheathing.
Following this dive the decision was taken to close down the work on the Endeavour Reef and prepare to head down the coast in Spoilsport to Flora Reef and the team from Nimrod / Silentworld.
I hope you have been following Alice and Megan’s blogs on the 2009 Mermaid Project over the last six days. Over the last couple of days the dive team have made a number of significant discoveries on Flora Reef. Two days ago during a magnetometer survey on the southern side of the reef the team picked up a small but impressive magnetometer signal about 150 meters offshore from what was then Flora Reef Unidentified shipwreck No 2. A team of divers were sent in and after only a short search located a 5 foot long, wrought iron kedge anchor sitting on top of a coral bommie in 7 meters of water. We know from historical accounts of the wreck that the crew of the Mermaid dropped a small kedge anchor about half a cable length from the stern of the vessel in an attempt to kedge (pull) the Mermaid off the reef. Their attempt failed and the kedge anchor and its coirfibre cable were abandoned.
In itself the discovery of the anchor did not proove that that the wrecksite was HMCS Mermaid and the team continued to survey the site looking for additional information. Yesterday a metal detector survey uncovered a series of anomlies scattered amongst coral rubble on the southern side of the site. These anomlies have now been identified as being casement or cannister shot (packets of ball bearings contained within a small canvas bag of small wooden cannister) the team have also found fragments of copper sheathing, sheathing nails, ship’s fastenings, lead patches and several large magnetic anomalies on the wrecksite. This information along with the position of the wreck and the size of its remains has meant that we are now quite positive that the site is that of HMCS Mermaid wrecked off the Frankland Islands in 1829.
Archaeologists, scientific divers and volunteers divers and snorkellers are continuing their investigation of the site hoping to reveal more information about this fascinating vessel.
