keel types
bar keel
flat plate keel
bar keel-vertical or upright members which increase strength,protects the boats hull plating if the boat grounds on a hard bottom. reduces rolling. it increases the boats draft extending below the plating.
flat plate keel-has a plate that is perpendicular to the centerline of the hull. a vertical center keel that runs internal to the hull at the centerline typically supports the flat plate keel.
define keel

which does the 47 have?
keel-the backbone of the boat. it runs fore and aft along the center bottom of the boat.

define:used to further explain fire combustion and extinguishment. removing one or more of the sides will cause the fire to be extinguished.

classes of fire and extinguishing agents used?
class Alpha-common combustable material (wood,paper,plastic) water,co2,pkp
class Bravo-combustable liquids (oil,fuel,lubricants) AFFF-aqueous film forming foam,co2,pkp
class Charlie-energized electrical equipment (switchboards,breakers) co2,pkp
class Delta-combustable metals (mercury) water wide v,sand under the object, jettison
three methods to apply water straight stream wide V-high velocity fog narrow V-low velocity fog flush
- long reach and penetrating power
- can cool a wide surface area
- less cooling surface area

static dynamic static dynamic
define static and dynamic
two forces that affect vessels stability.
static-weight within the hull(fuel,water,gear)
dynamic-actions outside the hull(wind,waves,swells)
stability define: longitudinal transverse righting moment
longitudinal-fore/aft. prevents it from pitching end over end
transverse-athwartship.stability tends to keep the boat from rolling
righting moment-is the force causing the vessel to react against a roll and to return to an even keel.

explain:
- cooling
- smothering
- chain breaking
- oxygen dilution
- reduces the temp below ignition point
- separates it from its oxygen supply
- disrupts the chemical process necessary to sustain a fire
- a smothering process that reduces the amount of oxygen available to a level below that required to sustain combustion.
define stability
the tendency of a vessel to remain upright
center of gravity
the point at which the weight of the boat acts vertically downward
buoyancy
the upward force of water displaced by the hull
equilibrum
when a boat is at rest, the center of buoyancy acting upwards(vertically) is below the center of gravity acting downward. at this point the boat is considered to be in equilibrium.
parts of a keel?
define
name
frames-attached to keel which extend athwartship(from one side to the other) the skin of the boat is attached to the frames. the keel and the frames strengthen the hull to resist external forces and distribute the weight.
stem-an extension of the forward end of the keel. there are a common number or shapes, all are normally slanted forward(raked) at an upward angle to reduce water friction.
sternpost- a vertical extention of the aft end of the keel
what is: displacement gross ton net ton dead weight
the weight of a boat , and is measured in long tons(2,240lbs)
the entire cubic capacity of a boat expressed in tons of a 100 cubic feet
the carrying capacity of a boat expressed in tons of 100 cubic feet. it is calculated by measuring the cubic content of the cargo and passenger spaces.
