Shoreside Questions with complete
Solutions
list burn types and treatments
1 - first layer of skin: water, bandaid
2 - 2nd layer of skin, causing blisters: water, bandaid
3 - all layers: call station, cover area
List Maine survival times
40-50: 1-3 hrs
50-60: 1-6
60-70: 2-40
list types of bleeding
capillary: slow oozing
venous: steady flow
arterial: spurts
what are the 3 types of hull?
displacement
planing
semi-displacement
What is a displacement hull?
pushes water away from the vessel or displace the water
What is a planing hull?
a displacement hull that, when acted on by certain forces, planes on top of the water
What is a semi-displacement hull?
, A displacement hull that can move up but never fully leaves the water
what are the types of keel?
Flat bottom: shallow draft, planes easy; less stable
V-bottom: stable, more control; smoother ride
Deep-V (rounded) - stable, controlled; smooth ride
Multi-hull: wide stance, very stable
State the factors that should be determined before you open watertight doors, hatches,
and scuttle covers on a damaged boat
a. flooding did not occur (then ok to open)
b. if flooded, further flooding will not occur if the closure is opened
c. use extreme caution opening compartments below the waterline near hull damage
how do watertight doors work?
door forced into a coaming
What two factors affect boat stability?
Gravity and bouyancy
CG is where boat force points straight down
What are the two forces that effect stability? Define
Static - affected by placement of weight on the boat
Dynamic - outside forces, wind, waves etc
define equilibrium
CB and CG are equal
define longitudinal and transverse stability
longitudinal: runs fore and aft, prevents pitching
transverse: runs athwartships, prevents rolling
what boat features influence stability?
