furling line
In the case of most offshore yachts, yes, they can be "reefed" (furled and tied down) to reduce the amount of surface area exposed to the wind. However this does depend on the type of furling gear used, some (mostly jibs) can only be used fully unfurled (In general a solid forestay is required for a roller-reefing jib.)
'Yearling', 'Curling', 'Hurling' and 'furling' (as in furling or unfurling a flag) come to mind; can't think of any more offhand, but I'll give it thought!
It work by moter to start off.
Action and reaction forces work while roller staking by the action force being that you and your roller skates move forward. The reaction force is when the roller skates slide backwards on the ground.

NO. The 86 is not a roller block.
A foam roller might work, but a foam pad is better. Stain is too thin to go on with a regular roller.

No
well you have to die
YES, they sure will.
