2. BASIC SEAMANSHIP
• SEAMANSHIP IS THE ART ,KNOWLEDGE,
COMPETENCE OF OPEREATING A SHIP, BOAT OR
OTHER CRAFT ON WATER.
• IT includes topics and development of specialized skills
including navigation and international maritime law and
regulatory knowledge, cables, small boat
handling,anchors,communication,sailing,engines.
3. Navigation
• NAVIGATION is the art and science of safely and efficiently
dire4cting the movements of a vessel from one point to
another.piloting uses water depth and visual references , while
death reckoning uses courses and distance from the last
person.
• Navigation also uses electronics such as GPS ,and LORON.
• Along with general navigation seamanship involves being
respond to weather at sea
• Seamanship also involves recognation of navigation with
BUOYS such as lateral marks,cardinal marks ,etc.
5. BOAT SEAMANSHIP
• A BOAT REFERS TO A NON COMMISIONED WATER BORN
VESSEL THAT IS NOT DESIGNATED AS A SERVICE VESSEL
• SERVICE CRAFT:
• THE TERM SERVICE CRAFT REFERS TO WATER BOERNE CRAFT
THAT ARE DESIGNED FOR SPECIAL USE. HARBOR TUGS,FERRY
BOATS,FLOATING DRY DOCKS ARE DESIGNED SERVICE CRAFT.
• COMBATANT CRAFT:
• COMBATANT CRAFT REFERS TO DESIGNED FOR COMBAT
ROLES PATRON , RIVERINE ARE SPECIAL COMBATANT CRAFT.
6. PILOTAGE
• Most commercial vessels of excessive size limits determined
by local authorities are handled in confined areas by maritime
pilots
• They are also experts in the geographical areas they work
7. MAINTANANCE AND DRY
DOCKING
• Seamanship involves the correct and adequate maintanance
of the ship structure and vessel to keep the vessel seaworthy
• Seamanship knowledge and experience is a integral part of dry
docking.This includes careful planning and adequate
preparations, dry-docking calculation and checks upon
departure.
8. TRADITIONAL SEAMANSHIP
SKILLS
• Traditional seamanship skills are less used in modern ships,but
are still practiced in training colleges and small ships.
• Boatwork is a traditional seamanship skills ,on commercial
ships this is usually limited to boat works and life boats.
• Other traditional practices are applying forms of address of
captain used in boat flag.
9. MOORING AND ANCHORING
• Seamanship applies to general mooring practices and
anchoring, and established marine procedures for anchoring,
this involves the use of drogues as applicable.
• Anchor work involves the understanding and awareness of
types of anchors ,cables and shackles.
10. TACKLE
• A Tackle is an assemblage of ropes and blocks, and is known in
mechanics as a system of pulleys.
• The simplest contrivance of this kind is the single whip, or girtline, which
consists of a rope rove through a single stationary block. By this
arrangement, a better lead is given the rope, but no power is gained by
it.
• But this arrangement is extremely convenient and often absolutely
necessary, as in hoisting articles from the holds to the upper decks, or
from the decks to the masts and yards.
• It is quite different, however, when the single block is movable, or
attached to the weight to be moved, and generally these two principles
obtain in all tackles, namely, that stationary blocks give no gain, but only
serve as a lead to the rope, and all increase of power is derived from
movable blocks.
• The block having the greatest number of parts of the fall should be
attached to the weight to be moved, in order to gain the greatest
mechanical advantage. The power gained is equal to the number of
parts at the movable block.
11. To Knot a Rope Yarn, Fig 19, Plate 8. Split in halves the
two ends of a rope-yarn, scrape them down with a
knife, crotch and tie the two opposite ends; jam the tie
and trim off the ends.
An Over-hand Knot, Fig. 20, Plate 8. Pass the end of a
rope (b) over the standing part (a) and through the
bight above (c).
Figure-of-Eight Knot, Fig. 21, Plate 8. Take the end of a
rope (a) round the standing part (b), under its own part
(d), and through the bight (c).
12. • A Reef Knot, Make an overhand knot, as before directed,
round a yard or spar; bring the end (a), being the next towards
you, over to the left, and (b) to the right, take (a) round (b),
draw them taut, and it is done, . This knot is used in tying reef
points and small stuff generally. Observe to bring the end out
next its own part, otherwise it will be a Granny’s Knot, which
jams and is difficult to cast off.
13. KNOTTING AND SPLICING
• A Bow-Line Knot, Take the end of the rope (a), In the right
hand, and the standing part (b) in the left, laying the end over
the standing part; with the left hand turn a bight of
the standing part over it; lead the end round the standing
part, through the bight again. The bight turned in the standing
part is often called a Cuckold’s Neck.
14. • A Running Bow-Line Knot, Take the end of a rope, round the
standing part (b) and through the bight (c); make the single
bow-line knot upon the part (d), and it is done.
15. • A Cat’s Paw, for the same purpose, Lay the end of a rope (a),
over the standing part (b), forming the bight (e), take the side
of the bight (c) in the right hand, and the side (d) in the left,
turn them over from you three times, and there will be a bight
in each hand (c d). Through these put the hook of a tackle
16. • A Sheep Shank, This is made for shortening a back-stay, &c.-a
half-hitch is taken with the standing parts (a) round the bights
(b), when it will appear like the figure.
17. • A Fisherman’s Bend, With the end part of a rope take two
turns (c) round a spar; a half-hitch round the standing part (b),
and under the turns (c); then another half-hitch round the
standing part (b). This is sometimes used for bending the
studding-sail halliards to the yard, but more frequently for
bending a hawser to the ring of an anchor, in which case the
end should be stopped down with spun-yarn.
18. DUTIES OF MID SHIPMEN
• STEERAGE officers (of the line) on board ship are generally
assigned to duty as officers of the forecastle, midshipmen of
the quarterdeck and tops, mates of the decks, hull and hold,
boat officers and junior officers of the divisions.
• A midshipman may also be detailed as assistant to the
navigator, or as clerk to the commanding officer; in one of the
latter capacities he will probably also act as signal officer.
19. BOATS
• There are three different methods of building
boats, namely:-
• The Carvel-built, which have fore-and-aft planks,
the edges meeting but not overlapping.
• The Clinker-built, also fore-and-aft planks, with
the edges overlapping each other, like shingling.
• The Diagonal-built, having, as the name implies,
their planking running diagonally, the inside planks
running in a contrary direction to the outside ones,
and their edges meeting.
• Boats are single or double banked, as they have
one or two rowers to a thwart.
20. RIGGING SHIP
WHEN a ship is taken in hand to be rigged, her lower masts are
standing, temporarily or permanently wedged, and with girtlines
on each side of the mast-heads. The bowsprit is in place, as are
also the lower dead-eyes for the lower rigging. Hearts on the
bowsprit and shackles on the bows may also be supposed in
place before the riggers begin work.
We will rig the bowsprit first, as the staying of the fore-mast
depends upon it, and would otherwise be delayed
21. ROPES
• THERE are four varieties of rope in the United States naval
service: that made of the fibres of the hemp plant; the Manilla
rope, made of the fibres of a species of the wild banana; hide
rope, made of strips of green hide, and wire rope.
• In some countries, ropes made of horse hair, of the fibrous
husk of the cocoanut, called coir-rope, and of tough grasses,
are quite common. In our own country, rope has been made
from the flax and cotton plants.
22. LIFE SAVING SERVICE
Rescue with the Life-Boat or Surf-Boat. The patrolman
after discovering your vessel ashore and burning a
Coston signal hastens to his station for assistance. If the
use of a boat is practicable, either the large life-boat is
launched from its ways in the station and proceeds to
the wreck by water, or the lighter surf-boat is hauled
overland to a point opposite the wreck and launched,
as circumstances may require.
23. • Rescue with the Breeches-Buoy or Life-
Car. Should it be in expedient to use either
the life-boat or surf-boat, recourse will be
had to the wreck-gun and beach apparatus
for the rescue by the breeches-buoy or the
life-car.
