第9题:
a watch which is kept with lower standard
a watch which is kept when the ship isnt sailing
a watch which is kept when the ship is sailing

第10题:
Downwind so that the apparent wind is close to nil
A course that will keep a free flow of air,clear of smoke,over the hoist area
A course that will have the hoist area in the lee of the superstructure
With the wind dead ahead because the helicopter is more maneuverable when going into the wind
第11题:
aid turning the ship
obtain a fine bearing
increase ship swings to wind or tide
lighten the stress of anchor chains
第12题:
A ship has to turn to stem the tide because the wind is strong when she is getting alongside a wharf.
Sometimes the wind is strong and the current is rough, so a ship has to turn to stem the tide when she is getting alongside a wharf.
The wind is big, a ship must get alongside a wharf so she has to turn to stem the tide.
A ship has to turn to stem the tide so she can get alongside a wharf.
