Nature’s lift for the Albatross
In his article in May Afloat Bruce Stannard informed us of the
plight of the Albatross. However, the flight of this bird holds an
According to New Scientist magazine, research into birds that
soar and glide over vast distances revealed that many of them
have black tops to their wings, Albatross, Ibis et al, and this
gives them 10-15% extra lift over birds with white topped wings.
One wonders whether any research has been done on how
this might affect the performance of black sails?

Invasion of the Killer Algae
Having just read Bruce Stannard’s article on the Shy Albatross
(Afloat May’18) I’d like to say Bravo Bruce, bloody well done! We
are entirely in agreement with the views you expressed on global
warming and the damage it causes to our marine environment.
We are stuffing our environment, and there needs to be a lot
more said and done.
We experienced more evidence of global warming just a
few days ago when leaving our berth in Stony Creek on Lake
Macquarie. We have never had trouble getting in and out of the
creek, but on this occasion we were brought to almost a stand
still from sea grass around the propeller, which required constant
reversing to clear it.
Once we were out I went for a swim and recovered the grass
from the prop. When we arrived at Port Stephens I showed it to
the local B.S.O. He was not sure what it was but did say they
were starting to find a lot of it around the Port Stephen area,
and it was causing big problems.
I have sent it off to be identified, but after some research on
the internet it appears to be Caulerpa taxifolia (commonly known
as Killer Algae).
This bright green noxious aquatic weed, introduced from
the Indo-Pacific, was found in the lake about 15 years ago. A big
effort was made then to eliminate it which involved taking 400
tons of salt to the affected area and covering it. We transported
the salt with our workboat Alkira. The job was declared a total
success at the time.
Unfortunately the weed is back and spreading. The powers
that be in the lake know about it but are taking the view that the
best way to handle it is to leave it and don’t disturb it.
From our experience in the creek it is too late for that. I am
sure that the extended warm weather and warmer water has
played a big part in its proliferation.
The Battle of Scorpius and Orion
I have been reading with interest Bruce Stannard’s article on
the declining numbers of the Shy Albatross in Bass Strait. As
ever y sailor knows, to see an albatross of any breed following your
ship is something of awe. To think that any breed is endangered
due to climate change is truly a blight on we the ‘smart apes’.
Climate change is a massive contributor as to why nature
is imploding. Also as Capt. Dick Gandy points out in the third
edition of his Boating Manual, a book that I used as my bible while
studying for my Master Class 5, the magnetic poles are splitting
and wandering. Does this contribute to climate change and/or
seasons changing? Last Christmas we were sitting around in
