G'day,

Sture's suggestion is the only one that would work, so far. A mast head
tricolour needs a non rotating tube inside the mast. This is possible, but
plays havoc at the base where it is rigidly fixed.

The spar with the original box section boom rotates with the boom. When I
fitted a wing mast on Harrigami, the mast rotated seperately to the box
boom. Worked well. The current boom is a diamond shaped structure, tied to
the boom. At present it more or less rotates with the boom, future versions
will rotate independantly. There will be a discussion of the pros and cons
of each on the web page in the near future.

Sture and others, you asked for some indicative materials prices. The
following are delivered to the wharf in Brisbane, Australia. I can get
quotes to any other port, but they usually have a gap for "local charges" at
the other end. Better that you make enquiries from local shipping agents.
Any problems, let me know.

For harrigami or harry:

400 gsm double bias glass 150 sq m $960
70 sq m 43 x 8mm kiri $2,050
300 litres Boat Cote epoxy resin $3,200 with choice of hardeners.

This is the material we use, as it does not have the bloom problems of WEST,
and is a simpler 2:1 mix ratio. http://www.boatcraft.com.au for
information on Boat Cote

We can also supply all the other materials required.

Regards,

Rob

Hi all,

Couldn´t the nav lights be mounted on a pole on each end of the leeward
hull (cannot be windward because they would be blanketed by the sails). I
remember Rob suggested something like this. On each pole would be a
combination red/green one monted high enough to be visible over the front
part of the WW hull (within the recuired angle) and a stern light lower
down. They would be wired so the red/green one in the bow and the stern one
in the stern, obviously :o) are connected. At the shunts there must be a
switch of some kind, automatic or manual, which turns on the other pair.
This would be enough for sailing.

For motoring just the red/green light would be used together with a white
masthead light. This should be legal as far as I know. Any sector light
cannot be mounted on a rotating spar. It does not always rotate 180 degrees
or.........

By the way, how much does the spar rotate when shunting upwind? Does it
rotate little enough for the sail to keep a clean leeward side with the
mast on the ww side?

Could the national flag be hoisted along one of the two shrouds? But how
high? And the courtesy flag and other banners on the other, higher up? Or
on the same one?

Sture Erickson
