Boat Handling Flashcards
1
Q
________ effects are a cause
of the single propeller action where water is displaced to one side or another, causing a movement of the hull from the deflection of the water flow.
The effects of transverse thrust when going ahead are so minimal they can generally be ignored but when operating astern propulsion, the water flow expels water in the forward direction. This in turn is deflected by the hull form causing a sideways push on the hull.
A
TRANSVERSE THRUST

Q
Anchoring
Shackles put out for anchoring in 16m
A
Calculation: 1.5 x square root
Square root of 16 = 4
4 x 1.5 = 6
Therefor 6 SHACKLES
