HAMPTON ROADS NROTC

learning objectives
Learning Objectives
  • The student will:
    • Have knowledge of different types of knots
    • Be able to identify different boat types
    • Identify parts of a sailboat
    • Have a basic understanding of how a sailboat operates
    • Have a better understanding of how wind and weather affect sailing
knots
Knots
  • Figure Eight
  • Bowline
  • Square Knot
  • Clove Hitch
  • Half Hitch
  • Sheet Bend
  • Proper way to secure a line to a cleat
slide5
Rig:

the configuration type of the mast and sails

Cat-rigged:

single or two-masted boat with NO jib (LASER)

Gaff-rigged:

sail is square with top edge supported by a spar called a gaff

Double-headsail-rigged:

two jib sails flown at same time, as found on cutters

slide6
Laser

sports an efficient “cat” rig with standard control lines (cunningham, outhaul, and vang)

low-drag, high lift foil section for the daggerboard and rudder

fast, responsive, LESS forgiving than other training boats

LOA: 14’

Displacement: 130 pounds

slide7
Dinghy: a small, light sailboat or rowboat
  • Small boat: a daysailor that is less than 30 feet long
slide9
Catamaran: a multihull with two hulls separated by a deck or crossbeams from which a trampoline is suspended
slide12
Ketch: a two-masted boat whose after mast, the mizzenmast, is shorter than the forward mast, the mainmast, and is located forward of the rudder post
slide13
Yawl: a two-masted boat whose after mast, the mizzenmast, is shorter than the forward mast, the mainmast, and is located after the rudder post
slide14
Schooner: boat with two or more masts, the forwardmost of which, the foremast, is shorter than the aftermast, the mainmast
standing rigging
STANDING RIGGING

Wire construction, holds mast in place under strain

b. Adjustable with turnbuckles

c. Permanently installed as long as boat in commission

d. Shrouds support athwartships; stays support fore and aft

running rigging
RUNNING RIGGING

Usually fiber line, or wire rope with fiber tail for halyard.

b. Adjustable, and can be unrigged between sailing periods

c. Used to control sails

d. Halyards hoist

e. Sheets trim or ease (change angle of attack))

f. Vangs and preventers restrain

cleats
CLEATS

Regular, horned type

stability
STABILITY

Ballast:

In centerboard dingy, provided by persons in boat

In Keel Boats, built into boat during construction

Hike out to counter wind gusts

Center of Buoyancy (CB)

The point on the boat through

which all Buoyant forces act

BOAT BALANCE

Center of Gravity (CG)

The point on the boat through

which all Gravitational

forces act

BOAT BALANCE

Center of Effort (CE)

The point on the boat through

which all Aerodynamic

forces act

Center of Lateral Resistance (CLR)

The point on the boat through

which all Hydrodynamic

forces act

Capsizing
  • Causes
  • Recovery From Capsizing
wind weather
Wind / Weather
  • True vs. Apparent Wind
  • Natural Wind Indicators
  • Onshore vs. Offshore Winds
  • Tides

Rule 2 (a) The Rule of Good Seamanship
    • Nothing in these Rules shall exonerate any vessel, or the owner, master or crew thereof, from the consequences of any neglect to comply with these Rules or of the neglect of any precaution which may be required by the ordinary practice of seamen, or by the special circumstances of the case.
    • This part can be paraphrased as “There ain’t no excuse.” Remember you can be relieved of your command in the event of a collision.
slide51
Rule 2 (b) The General Prudential Rule
    • In construing and complying with these Rules due regard shall be had to all dangers of navigation and collision and to any special circumstances, including the limitationsof the vessels involved, which may make & departure from the Rules necessary to avoid immediate danger.
    • This can be paraphrased as “Always use common sense.” Note that this rule says that a departure from the Rules may be required to avoid danger. The “special circumstances” noted most often are situations involving more than two vessels The other Rules only address those situations involving two vessels.
slide52
Rule 12 Sailing Vessels
    • (a) When two sailing vessels are approaching one another so as to involve risk of collision, one of them shall keep out of the way of the other as follows:
      • (i) when each has the wind on a different side, the vessel which has the wind on the port side shall keep out of the way of the other;
      • (ii) when both have the wind on the same side, the vessel which is to windward shall keep out of he way of the vessel which is to leeward; and
      • (iii) if a vessel with the wind on the port side sees a vessel to windward and cannot determine with certainty whether the other vessel has the wind on the port or on the starboard side, she shall keep out of the way of the other.
    • (b) For the purpose of this Rule the windward side shall be deemed to be the side opposite to that on which the mainsail is carried
rule 13 overtaking
Rule 13 - Overtaking
  • Notwithstanding anything contained in Rules 4 through 18, any vessel overtaking any other shall keep out of the way of the vessel being overtaken.
  • This states that you should keep clear when passing another vessel. Note that there is no stipulation of a vessel under sail or a vessel under power.
rule 18 responsibilities between vessels
Rule 18 - Responsibilities Between Vessels
  • Except where Rules 9, 10 and 13 otherwise require:
    • A power-driven vessel underway shall keep out of the way of:
      • a vessel not under command;
      • a vessel restricted in her ability to maneuver;
      • a vessel engaged in fishing; and
      • a sailing vessel.
    • A sailing vessel underway shall keep out of the way of:
      • a vessel not under command;
      • a vessel restricted in her ability to maneuver; and
      • a vessel engaged in fishing.
    • A vessel engaged in fishing when underway shall, so far as possible, keep out of the way of:
      • a vessel not under command; and
      • a vessel restricted in her ability to maneuver.
