3/02/2014 Anchoring,
Anchoring, Bloody Anchoring.
The past few days on our Sailing Around Australia Adventures, have
been taken up with working out the best place to hide from the strong Easterly
Gales that have now set in to Duke of Orleans bay.
The art of anchoring on Easy Tiger is perfecting the dropping of 25
kilos of steel on to sand on the ocean floor. Then having it fall on to the ocean
floor the right side up so that it buries into the sand. Then you have to get
it to actually bury into the sand and trust that it will stay there while
attached to 50 or so meters of chain, from which is dangling the pride and joy
that you have just invested your life savings (and then some) into. If you drop
it into weed it will roll the weed up into a ball and sit on top of that, not
bedded in and not holding. You then expect that this 25 kilos of steel, will
stop a 9 tonne boat from being pushed by 40 to 50 kilometres an hour winds
either on to rocks or beach or even from ending up in a different post code
from where you started.
This is attempted with an anchor witch of a winch that is supposed
to wind up the or down the 50metres of chain, the anchor witch is at the front
of the boat just a little too far back to be able to see what is happening to
the anchor chain as it disappears into the water by the person on the bow. The
person controlling the boat is at the back on the port side and cannot see the
anchor, the anchor chain or the person on the bow. We use headset transmitters
and receivers to solve this problem. The thing is, so do Brian and Maree on
Urchin. Sometimes if we are working in the vicinity of Urchin as they are
anchoring, I can pick up Maree, not Leanne and Brian gets Leanne. Other times
the wind is too strong and noisy for any of us to hear anything at all through
the headsets.
From these descriptions I hope I give you the picture that anchoring
can be quite a frustrating and tricky activity. The possibility of anchoring
lead divorce is off the scale.
So almost as much thought and planning is put into when, where and
how we will be anchoring at the end of each journey.
To determine the best place to be so that we can be protected as
much as possible from nature’s forces, we look at the weather up to 4 days in
advance, to determine the wind strength and direction, as well as the swell
height and direction.
We then have a couple of books and internet sites, plus nautical
charts that show us the geographical outlines of the surrounding areas. So in
an easterly wind we want to be on the west side of headland or a hill, for
example.
We received a forecast on Friday, that Monday would see Easterly
winds at 20 to 30 knots in our area. Consultation to the books and a look at
the chart showed that a bay called Victory Boat Harbour would be well protected
from the east.
Closer inspection of Victory Boat harbour on Google earth, showed
that it also has a sandy bottom, which is a real treat for us. A meeting
between the three boats was held. It was decided that we needed to look at the
possibility of moving the 6 or 7 nautical miles around to Victory Boat harbour.
Then a question from Maree came, “ What about the swell?” We hadn’t looked at
that.
Back to the books, back to google maps, back to the weather forecasts.
All this revealed that a large southwesterly swell was forecast. A large
southwesterly swell would enter Victory Boat Harbour. The last thing we need
when anchored is to have waves breaking on top of the boat. Also on closer
inspection, the anchorage at Victory Boat Harbour is quite narrow and we would
have to anchor in single file. That would mean the one closest to shore could
be smashed by the breaking swell, the one the furthest out would not be
protected from the wind and if the one in the middle dragged anchor it would
collide with one of the others. No-one could sleep with those possibilities, so
the re-anchor in Victory Boat harbour was abandoned. We decided to stay in Duke
of Orleans bay.
Nares Island to the south seemed to be quite exposed to the east.
Table Island to the North West was where we had anchored the other day in
strong winds, to find that the wind came in bullets after “wrapping” around Table
Island. Plus to get protection we needed to be dangerously close to the
unforgiving rocks. (see previous blogs).
It was back to Nares Island as the best of a bad lot. Once we
arrived in the area, we drove around, around and around some more, looking for
a suitable patch of sand to drop our anchor into. There are only a dozen or so
clear patches of sand around Nares Island. Four of these are taken up by
locals, who have put down permanent moorings for their boats. B2 on Zofia had
anchored nicely in a big sand patch but that made 2 others inaccessible for us.
It was looking like we were going to have to try our luck by
dropping into the thick ribbon weed. Finally we saw a patch of sand about the
size of your average coffee table. It was close however and I mean very close
to a local’s small catamaran that is swinging about on a permanent mooring. We
managed to get the anchor in to the sand OK and have spent the time since
watching Easy Tiger move around in a sort or circular dance with the other
boat.
On Friday morning after our weather and planning get together we saw
B1 and Maree from Urchin wandering around in their dinghy. They were inspecting
their anchor it seemed. I went over in my dinghy to see what the fun was about.
They explained that they thought their anchor chain was snagged on something
and once we got the dinghies arranged into the right position we could see
their anchor chain wrapped around a train wheel on the bottom of the ocean. Old
train wheels are often used as anchoring points for permanent moorings.
After many attempts to haul their chain clear from the train wheel
snag from the dinghy, it was decided that the only way to get it free was for
someone to dive on it. So Maree suited up while B2 and I arranged our dinghies over the top of
the anchor. Down she went into the weedy, cold depths. After a few bubbles and
some super human effort from Maree, the chain was freed.
Next morning I got up to find our anchor buoy off our starboard side
hull. Normally this would be straight out from the middle of the boat. OH
NO! it seemed like we were snagged. I
hatched a plan to un-wrap our chain by driving Easy Tiger around in a circle
and letting out or pulling up the chain as we went. The last thing I wanted to
do is dive into the weedy, dark, chilly water.
To my great relief on the first pull the boat came right up to the
anchor, meaning we weren’t snagged at all.
On Saturday we got a call from people we met in Esperance that also
own a Fusion 40. Fud and Faye Mackenzie said that they would like to drive out
from Esperance and pay us a visit. How nice this was. They offered to bring
supplies (a godsend) and Fud offered to drive us around to Victory boat harbour
to have a look should we want. What great people Fusion 40 cat owners are.
When we relayed all our bad anchor stories to Fud on the
Its just a matter of trusting that you have successfully dropped of
25 kilos of steel on to sand on the ocean floor. Had it fall on to the ocean
floor the right side up so that it buried into the sand. Now trust that it will
stay there while attached to 50 or so meters of chain tied on to a 9 tonne boat
that is being pushed by 50 kmh winds towards the beach.
What’s to worry about?
This little catamaran is moored on a permanent mooring. If we drag our anchor it may become our new hood ornament. |
One advantage of being anchored near weed. Leanne caught a squid. |
