Launch
Prelude
Before completing the work on the boat by
early August 2006 I revisited the Goolwa Barrage as I was getting nervous
about the Water Authorities agreement to open the removable section to
allow Alcatraz through in order to exit the river.
It was soon confirmed that in view of the
drought they wouldn't be able to open it until April 07 at the earliest
and then there was no guarantee.
There was a suggestion I consider crane launching
at the boat-ramp about 5 kms down river and after inspecting it and the
state of river mouth I decided to adopt this strategy.
Having confirmed this it took 6 weeks to
get all the different permits and clearances needed, which I won't elaborate
on as they will be different for everybody. Suffice it to say it should
be very early on any agenda to build a boat to find out who the local
authorities are and what they will / will not let you do.
From the beginning I had always anticipated
to load the boat onto the truck without the use of a crane as I felt we
could jack it up prior to the trucks arrival and then lower it down onto
the truck once it was in position.
In preparation for the move the boat was
partially jacked up, using 4 Ton bottle jacks and cement blocks under
the cradles it was build on. We worked the fore and aft pairs consecutively
to minimise the lateral load on the cradles, but quit after raising the
boat 400 mm, in lieu of 600 intended, as they were starting to show signs
of stress. We decided the final 200 could be jacked once the truck was
in position. The ute parked underneath illustrates how much room there
was.
Day 1 - Loading the boat
To get the truck under the boat, with the
paddock grass still not fully dried out, it had to back up the our access
road up a reasonably steep hill. It could not manage it by itself and
2 tractors from the vineyard next door helped by pulling it up and the
under the boat. Achieving the correct positioning was aided by the tyre
alignment lines I spray painted on the surface.
Once positioned under the boat the ramps
were lifted up in the transport position and only just cleared the bow
beam.
The trailer was an air pneumatic type that
could adjust the width of the bed in addition raising itself vertically
by 200 to pick up its load. After the width was set we build up under
the bulkheads (Mast & Aft) with hardwood pallets.
Once these were in position the spreader
beams I had made up in advance were temporarily placed and the boat was
jacked up a further 200 mm whilst the truck supported most of the load.
Following the jacking, the spreader beams were removed, more pallets inserted
and the spreader put back.
The boat, pallets etc. were then secured
to the truck with numerous webbing straps as the truckie was nervous about
the load shifting on the way down the hill
Day 1 - Moving off the block
Once the truck negotiate the bend just out
of the tunnel it disappeared down the hill that quickly most of the on-lookers
were caught out and left behind. The corner at the bottom, which was anticipated
to be a big problem again negotiated without a fuss.
After a loop diversion into a paddock to
get around a very tight corner a set of handrails along a culvert, spaced
5 m apart, was avoided by straddling one side.
The final major hurdle was the railway crossing
signal lights, which were to close together, despite my protestations
at the time they were erected (I'd started to build by then) This was
overcome by a crew laying one light down without disconnecting it, while
the truck passed.
After the rail crossing we pulled over on
the verge, which was 8 meters wide, where we spend the night after a long
day.
Day 2 - Road Transport
The journey this far had only been 400 meters
from the block on small lanes which the council had given me permission
to close while we on there, the rest of the journey was on the Department
of Transport controlled roads, for which I had to, obtain a permit.
The conditions associated with the permit
were 2 motorcycle police escorts, 2 escort vehicles and a team in front
and behind the procession to dismantle and re-erect signs as required.
Also travelling times were restricted to minimise traffic congestion.
The photo shows the truck travelling through
Littlehampton, a small village, at 7.15 am. As part of the follow up team
I got to realise just how many people, all keen to get to work, get held
up by an exercise like this.
The route nominated by DoT send us inland,
the first 30 km portion along the freeway, where the truck must have travelled
at the speed limit, 110 km/hr
Once, off the freeway, things slowed down
a bit, especially where the road undulated or where we had to negotiate
obstructions, culvert edges, roundabouts etc. but the 80 km journey to
Goolwa was completed in about 1.5 hrs. In fact we got there too early
and had to wait for the shool traffic to stop
Day 2 - Unloading & Launch
Once we'd arrived at the boat ramp we had
to wait for an hour before the crane arrived, as we were early. When it
did we unloaded the mast first in order to re assemble the forward jumpers
(removed to minimise the load height)
The crane then set up at the boat ramp, from
where it could lift both the boat and the mast within its load radius.
The boat was launched utilising the lifting
eyes I'd build in during construction and because both the fore and aft
sets were build into bulkheads we used no lateral spreader beams.
The fore & aft spreader was more for
convenience then load distribution.
The rigger didn't quite get the balance right
in the way he rigged the spreader beam and as a result the boat lifted
dipping forward.
This could have be awkward if we'd lacked
depth, but as things turned out the crane had plenty up its sleave, as
the load indicator clocked in at a fraction over 7 Ton (there was about
a ton of water/fuel and supplies aboard). He could extend out far enough
to have plenty of depth under the bow.
Once in the water I quickly inspected both
hulls and was happy to see there were no leaks. Also she was floating
nicely on her lines.
Day 2 - Mast
The mast was then lifted and positioned by
the crane and as the stays had already been swaged, secured and finally
aligned. The mast and rigging clocked in at 0.2 T, which indicates a dry
weight of about 6.2T for the completed vessel.
Here the rigger can been seen unhooking the
sling when the mast was secure.
Total cranage for the exercise, without travelling
was 4 hours.
After a long day, we were glad to get away
from the ramp and we anchored just down from the barrage where we awaited
the right conditions to exit the Murray Mouth.
As things turned out this happened within
days, before we'd had a chance to rig the furler and sails, so we motored
out and from there to Victor Harbor on the way to Wirrinna Cove marina
in Gulf St Vincent
Once we were there we had ideal conditions
to complete the job which is just as well as I had to get up to the top
of the mast to install the wind vane/transducer.
