Merry Christmas to all

Merry Christmas to all

s/v Code Blue Followers, 12-24-14

Just thought I’d send a Merry Christmas note to everyone. We’re in
Whangarei Marina, New Zealand. Here’s our Christmas picture for you. They
are having a potluck at the marina for Christmas eve. We’re headed into
Auckland to spend some time with fellow boaters for Christmas dinner and
then some activities in Auckland the next day.

We’ve decided on 393 Hydra Net by Dimension Polyant sailcloth for our Genoa
with tri-radial cut pattern and 8.77 Marblehead Dacron by
Challenge Sailcloth for the main. Both of these are about 8.5 oz.
material. The Hydra Net is a woven material with Dyneema in the cloth.
Here’s a link for Hydra Net.

Our choice of sail maker is Calibre Sails who designs and makes the sails
in their Whangarei sail loft.

Dyneema from Wikipedia
*Ultra-high-molecular-weight polyethylene* (*UHMWPE*, *UHMW*) is a subset
of the thermoplastic <http://en.wikipedia.org/wiki/Thermoplastic>
polyethylene <http://en.wikipedia.org/wiki/Polyethylene>. Also known
as *high-modulus
polyethylene*, (*HMPE*), or *high-performance polyethylene* (*HPPE*), it
has extremely long chains, with a molecular mass
<http://en.wikipedia.org/wiki/Molecular_mass> usually
between 2 and 6
million u <http://en.wikipedia.org/wiki/Atomic_mass_unit>. The
longer chain
serves to transfer load more effectively to the polymer backbone by
strengthening intermolecular interactions. This results in a very tough
material, with the highest impact strength
<http://en.wikipedia.org/wiki/Impact_force> of any
thermoplastic presently
made.[1]
<http://en.wikipedia.org/wiki/Ultra-high-molecular-weight_polyethylene#cite_note-1>

UHMWPE is odorless, tasteless, and nontoxic.[2]
<http://en.wikipedia.org/wiki/Ultra-high-molecular-weight_polyethylene#cite_note-2>
It is highly resistant to corrosive chemicals except oxidizing acids
<http://en.wikipedia.org/wiki/Oxidizing_acid>; has
extremely low moisture
absorption and a very low coefficient of friction
<http://en.wikipedia.org/wiki/Coefficient_of_friction>;
is
self-lubricating; and is highly resistant to abrasion
<http://en.wikipedia.org/wiki/Wear#Abrasive_wear>, in
some forms being 15
times more resistant to abrasion than carbon steel
<http://en.wikipedia.org/wiki/Carbon_steel>. Its
coefficient of friction is
significantly lower than that of nylon <http://en.wikipedia.org/wiki/Nylon&gt;
and acetal <http://en.wikipedia.org/wiki/Polyoxymethylene>, and is
comparable to that of polytetrafluoroethylene
<http://en.wikipedia.org/wiki/Polytetrafluoroethylene>
(PTFE, Teflon), but
UHMWPE has better abrasion resistance than PTFE

A fellow boat we know has had Hydra Net sailcloth for their sails with 7
years service and 80,000 miles.

It’s summer here but still we get wet once in a while. Drier after the new
year they say and hopefully sunny.

Merry Christmas and Happy New Year
