Marine Anchors

Mariners take it for granted. Landlubbers seldom give it a thought. And yet the
Anchor has become a symbol of the very sea itself. On this one page, we hope
to give you a brief history of its development.
Primitive & Ancient

When man first invented the boat and took to the water, he soon discovered
that tides, currents and winds often took him where he didn’t want to go. And
this was particularly irritating when he wanted to stay right where he was. So
he invented the anchor. The first anchor (and it seemed like a good idea at the
time) was simply a heavy stone tied to a crude rope. Several lost boats later,
grooves were cut into the stone to stop the rope from slipping off.
But weight alone was not enough to hold a boat in one place for long. An
efficient anchor needed some kind of hooking device. So the early boatmen
added wooden crosses or iron hooks to their stones to increase the holding
power. These “killicks” are still used by primitive peoples around the world.
The Chinese developed true hooking anchors 4000 years ago - and they’re still
standard equipment on Chinese junks! Double-armed anchors with opposing
stocks were known to the ancient Greeks in the 8th century B.C., and a
Sardinian Scarab dated 650 B.C. shows a stockless double-armed anchor,
thought to be the first anchor made of iron. Three or four hundred years later,
vessels of the Athenian Navy were carrying iron anchors weighing nearly 500
pounds. And at about this time came the first rudimentary palms. Ships could
now drop anchor, and reasonably expect to stay where-they were. But there
were still plenty of improvements to be made.

British Anchors
The Britons were late starters in the anchor-making business - the earliest
known British anchor is a mere 2000 years old! The first English iron anchors
are said to have been forged in East Anglia in 578 A.D. They had very small
palms, and were designed to be used with a wooden stock. The Bayeux
Tapestry shows what could be the first imported anchor being carried ashore
by the invading Normans. By this time anchor making was a growing trade,
and anchor-smiths even had their own Patron Saint. Known as St. Clements
4th Pope said to have been thrown into the sea tied to an anchor. This was a
then known form of execution.

In the 15th century, the Statutes of Genoa required a 1500 ton ship to carry
twelve anchors weighing well over half a ton each. And the large, traditional
Kedge type anchors with wooden stocks were seen on the ships of the great
navigators of the day. Kedges were effective, but extremely heavy. And the
development of iron stocks in the late 18th century didn’t do much to solve the
weight problem. But over the years gradual improvements took place. Better
welding. Shorter shanks. Increased arm curvature. And by 1846 the Royal
Navy had adopted the modified ‘Admiralty’ iron-stocked kedge. Meanwhile,
however, work had been going on in other directions. Notably the
development of a tumbling fluke anchor introduced in 1818 by one Lieutenant
Belcher R.N. Cant-palms had been added to Belcher’s design by aman named
Trotman, and in 1852 a British Commission declared that the Trotman anchor
was the best anchor of all. But its success was short-lived - due largely to the
development of the Hawkins patent tumbling fluke stockless anchor. The
great advantage of the stockless anchor is the ease of stowage in a hawse pipe;
and today stockless anchors are practically the only type used on larger ships.

1 ORDINARY PATTERN ANCHOR This
traditional design, known variously as the
“Admiralty”, “Kedge” or “Common” anchor,
became established with the Royal Navy in its
present form around the middle of the last
century. And it’s still in use — mostly on small
fishing vessels — to this day. I
The anchor is manufactured in weights from 1
cwt. to 40 cwt. (50 to 2000 kilos).
2 SINGLE ARM MOORING ANCHOR Used
principally as a permanent mooring anchor, its
single arm feature prevents fouling of other .
vessels at low tide. The crown shackle is fitted
to facilitate removal and for fixing of a marker ;
buoy line.
Manufactured in weights from 56 lbs. to 30 a
cwts. (25 to 1500 kilos).
3 PLOUGH ANCHOR Developed
before the last war and recently re-designed,
this anchor is popular with small boat owners.
It’s an efficient anchor, but doesn’t equal the
performance of the Meon anchor of comparable
weight. \
The plough is made in weights from 5
Ibs. to 280 Ibs. (2 to 128 kilos.)
4 MUSHROOM ANCHOR First introduced ‘
more than a century ago, the Mushroom is used
mainly for lightships and other permanent
moorings, or when the bottom is soft and
muddy.
The Mushroom is manufactured in weights
from 1) lbs. to 20 cwt. (% to 1,000 kilos). la
SMALL MUSHROOM ANCHORS The Small /
Mushroom is a really new idea. It’s nylon is
coated, with no sharp corners. So ot’s just the ‘a
job for a rubber dinghy particularly in muddy C—— y |
bottomed rivers and sandy shores. f
Small Mushroom Anchors weigh approximately y p Sa
3 Ibs. (1% kilos). (3 y a

(FISHERMAN TYPE( The popular Fishermen ?

Anchor has remained virtually unchanged since :

1846, and its history has been much the same

as that of the Ordinary Pattern Anchor. It’s still D
a favourite today, especially with fishermen

operating around rocky shores. ZA d s
Manufactured in weights from 4 lbs. to 150 Ibs. 5 ;

(2 to 70 kilos). Z

6 COMMON ANCHOR This anchor similar to ~ S

the Ordinary Pattern Anchor, is also in general

use on small fishing vessels. Its development

following closely that of the “Admiralty” and }

“Kedge” anchors.

Manufactured in weights from 30 lbs. to 230

Ibs. (14 to 100 kilos(.

7 ROND ANCHOR The Rond is strictly for river

or canal use. Made in weights from 1 lb. to 3

Ibs. (2 to 1/2 kilos) it’s used by simply sticking

it into the bank.

8 FIVE PRONG GRAPNELS The Five Prong 38
Grapnel is really no more than a five fluke

anchor, fitted with a collar. It’s manufactured in :

weights from 4 lbs. to 112 lbs. (2 to 50 kilos)

but larger sizes can be specially made to order.

The Grapnel is ideal for use on rocky shores 7

and for inshore mooring of small craft. It’s used

too, as a grappling iron, and for dragging the A
river clearance. .

The principal market for Grapnels is South

America, where they are used for gold /
prospecting as well as for normal marine

applications.

9 A.M. 12 ANCHOR A single Fluke Anchor SN

developed by the Armiralty for permanent Navy

moorings.

10 A.C. 14 ANCHOR This is the Admiralty

High Holding Power Anchor, designed by them

for Navy use. Better suited to recessed type

stowage now considered necessary in a [}

warship. Although principally used by the tg

Royal Navy it is available commercially, where

the Classification Societies apply the 25%
weight concession rule.

CHASING
The Bruce anchor is recognised as the ideal anchor design for chasing applications.
Its fluke to shank separation eliminates any possibility of chaser jamming while its
centre of gravity ensures an easy transfer from the semi-submersible’s anchor rack
due to the natural tendency of the anchor to tip forwards during this procedure.
For the same reason, anchor lifting during retrieval is easy and the risk of the chaser
slipping off the anchor, and picking up a bight of chain or mooring cable, is
eliminated.

The new design gives a better grip in sand. Because
of a higher centre of gravity the anchor will quickly settle
in correct position, and the new shape of the flukes will
ensure a better grip.
SAV Folding Anchor takes a minimum of space to store,
and has no sharp edges that can cause damage to deck
and topsides.
