Study Notes
Military Science 2 Chapter 3
- Marlinspike
- Knots, Bends, and Hitches
- Deck Seamanship
- Painting
Marlinspike Seamanship
- Marlinspike Seamanship involves handling and working with fiber and wire rope, including knotting, splicing, serving, and fancy work
- Lines are used for mooring, docking, rigging and painting
- Wire Rope is typically used for supply replenishment and highline transfers
Rope
- Rope is made from wire, fiber, or a combination of both materials
- Fiber rope, also known as line, is made from natural or synthetic fibers
- Sailors refer to fiber rope as line and wire rope as rope or wire
- A line is a piece of rope, either fiber or synthetic, used for a specific purpose, like a lifeline, heaving line, or lead line
Construction of Line
- Navy lines: three-strand, braided, or plaited construction
- Three-strand line is made by twisting fibers into yarns, yarns into strands, and strands back into line
- Lines are twisted into cable in the Navy
- Line's lay is determined by direction strands are twisted
- Lines twisted to the right are right-laid
Use and care of Line
- Coil right-laid line right-handed or clockwise and that braided and plaited line should be flaked
- Lines should be kept separate from stays, guys, and standing rigging
- Surging lines around bitts, take off enough turns for smooth surge
- Splice chafed/damaged lines, after cutting, do not cut a line without permission
- Do not lubricate lines
- Whip all line ends for care
- Fiber line is subject to frequent inspection of the fibers and internal wear.
- Lines dragged over sharp or rough objects will break outer layers and cause the inner layers to cut.
- Atmospheric exposure will deteriorate lines, up to 30% in 2 years.
- If you discover a supply of lines that are 3 years old, they should be returned noting its uneconomical state.
Small Stuff
- Line with a circumference of 1 1/2 inches or less is considered small stuff or threads
- Round line is three-strand, right-laid tarred hemp and it is used for seizing and servings where neatness is required.
- Sail twine is small stuff laid up right-handed by machine and is used when a fancier job is desired like a marline
- Cod line is a light, white line used decoratively and previously used in hammock clews for suspending a hammock.
Securing Ends
- Never leave a line end dangling loosely without whipping to prevent unlaying. Fraying happens on its own
- Use temporary plain whipping of rope as a preventative measure
Knots
- Bowline knot is versatile and made for loops as they are required
- Naval Seamen use knots to bend lines back to themselves forming secured eyes or knobs
Bending to a Hook, Ring, or Spar
- Hitches can secure a line to a hook, ring, or spar
- A hitch differs from a knot when tied to a ring, spar, stanchion, or another line but not tied back on itself to create an eye or bend two lines.
Eye Splice
- Eye splice with manila or synthetic lines requires untwisting the line's strands anywhere from 4 inches to 2 feet
- Then splice into the standing part by tucking unlaid strands from the end into the standing part
Short Splice
- Short splices join lines when an enlarged diameter isn't critical as when constructing slings using short spliced lines
Four Classes of Knots
-
Class 1 Knots: Knots in the end lines, fastening a line upon itself or around an object -Overhand Knot -Bowline -Running bowline -Bowline on a bight -French Bowline -Spanish bowline -Sheepshank -Cats Paw -Figure Eight -Black Wall Hitch
-
Class 2 Knots: Knots for binding two lines together -Square or reef knot -Granny knot -Sheet or becket bend (single) -Sheet or becket bend (double) -Two bowlines -Carrick Bend -Reeving line bend
-
Class 3 Knots: Knots that secure a line to a ring or spar (hitches or bends) -Fisherman's Bend -Tolling hitch -Round Turn and Two Half Hitches -Clove or Ratline Hitch -Half hitch or two half hitch -Stopper hitch -Cats paw
-
Class 4 Knots: Knots used to give finished to the end of a line and to prevent unreeling or for ornamental purposes -Wall knot -Crown knot -Manrope -Mathew Walker
Wire Rope
- Wire rope's fundamental component is a single wire made of steel or other metals in varying sizes twisted into strands.
- Strands in a wire will vary based on the purpose of rope
- Strands are laid to form the rope itself
- The denomination of rope is designated based on stands numbers on the rope over the number of wires on the strand.
- Diameter consistency is shared between 6 X 19 and 6 X 37 wiring
- Wire rope is made out of annealed steal, traction steal, or improved plow steal that is treated with either plain or galvanized.
Deck Seamanship
- Rigging is a significant part of deck seamanship, ship's standing rigging consisting of lines, wires, turnbuckles, and gear supporting the stacks, masts, and topside structure.
- Running rigging uses rigging to hoist/lower heavy weights or position/operate movable deck gear.
Ground Tackles
- Ground tackles consist of equipment used to moor and anchor, the list of tackle equipment is as follows: -Anchor chain, wire rope, synthetic line -Connecting/Detaching shackles/links -Pear-shaped links -End links -Bending shackles, mooring shackles, mooring swivels, detachable-link tool sets -Clear hawse pendants, dip ropes, chain stoppers, wrenches for chain stoppers, outboard swivel shots -Chain cable jacks, mooring hooks, chain hooks, and anchor bars
Types of Anchors
- Types include: stockless lightweight or stock-incrown, and two-fluke balanced-fluke anchors
- Stock anchors and mushroom anchors are no longer specified for Navy ships
Stockless Anchor
- Three designs of stockless anchors are used on naval ships: commercial, standard Navy, and the Mark 2.
Lightweight Anchor
- The Mk 2 LWT and wedge block LWT anchor are two types of lightweight anchors for Navy ships
Two-Fluke Balanced-Fluke Anchor
- Two-fluke balanced-fluke anchors are found on newer submarines and surface vessels as they are normally housed at the bottom of the ship
- Additionally its bower anchor is in place for its anti-interference with ships sonar dome.
Stock Anchor
- Stock anchors have been abandoned by merchant and Navy ships for being difficult to stow.
Mushroom Anchor
- Mushroom anchors resemble a mushroom with a long, narrow stem resembling a shank
Chain and Appendages
- Navy anchor chain of the flash butt welded type is standard for new ship constructions
- It replaces die-lock chain as required for back fit an made of several common links
- Variety of equipment and fittings provide anchor chain maintenance
Chain and Appendages (cont.)
- Detachable Links
- Chain Swivels
- Chain Stopper
- Mooring Shackle
- Mooring Swivels
- Clear Hawse Pendants
Anchor Windlass
- Windlasses are used to handle/secure the anchor, chain and for towing
Deck Fittings
- Deck fittings are devices attached to the hull and assist in the handling and securing the ship.
Painting Navy ships to protect surfaces
- Protects metal surfaces
- Paints and varnishes decorate surfaces
- Good paint is required to fight rust properly on metal surfaces
Preparing Surfaces for Painting
- The most expensive paint is useless without an excellent foundation
- Surfaces should be cleared, with no loose paint and fully prepared steel
- Remove all scale, grease, rust and/or moisture to prevent covered rust
- Steel treatments and coats very depending on steel plating
Tools for Removing Rust and Old Paint
- Scraper
- Wire Brush
- Sand Paper
- Chipping Hammer
- Scaling Hammer (Jitterbug)
- Rotary Power Brush
- Power Sander
- Rotary Chipping Tool
- Blow Torch
Application of Paint for Brush
- Handle brushes near the handle, keep hands clean of leads, or small cuts
- Angle right to the surface starting the return stroke
- Only partially fill brushes for the end bristles to contact the surface. Dont overcharge brushes on usage
- Make long, parallel strokes with wood grain direction
- For vertical surfaces layout vertically.
- For overhead surfaces, ceiling panels should be laid off fore and aft and the beams athwartships and keep paint well-mixed
- Thin coatings is best to obtain good results
Types of Paint Brushes and Uses
-Flat Paint Brush - large surface -Oval Sash and Trim Brush - small surface -Fitch Brush - small and small surfaces -Oval Varnish Brush - rough -Flat Varnish Brush - medium work -French Bristle Brush - high grade work -Lettering Brush -small surface & large work -Painter Duster- cleaning work
Care of Brushes
- Before using, rinse brushes with paint thinner and soak in boiled oil for 48 hours to make them flexible/easy to clean, containerize short-term storage, or distortions may occur.
Care of Brushes After Use
-The bristles must not touch the bottom as they get distorted eventually. -Brushes must be cleaned to prepared for their next deployment -Hang Brushes to dry or wrapped in wax to use at a later time -Do not soak brushes as the bristles will eventually come apart
Proper Cleaners for Brushes with Different Finishes
-Oil-based paints and varnishes -Water-based paint -Shellac -Lacquer -Enamel paint =turpentine or mineral spirits. =water =alcohol =lacquer =paint thinner
Painting Safety precautions
- Complete ventilation of the compartment to ensure immediate removal of vapors and paint dusts.
- Wear clothing that fits smartly to prevent the user from dusts and particles.
- Approved respirator for protection by covering skin with petroleum.
- Smoking, open flames, welding, grounding of spray equipments, chipping, and other spark-producing operations are prohibited in the compartment to lower any chance of ignition.
- Use explosion proof portable lights.
- Bulbs must not be replaced until the ship is completely ventilated.
- Approach old vented areas with caution.
- Avoid direct contact of varnish as cuts can become harmed
- Be wary in confined spaces
- Use cold water for irritation, and consult the medical officer
- Use hand soap on skin to avoid being poisoned by turpentine/spirits
