As the purpose of the foot rope is to limit the stretch of the foot of
the sail, using a nylon rope would defeat the basic reason for the
roping as nylon rope has up to 40% stretch and it would be impossible
to sew the rope to the sail to do this - it would mean that the foot
would be 40% shorter with tension released.

Just because it can be stretched to 40% elongation with_ some_ amount
of force, doesn't mean that this is magically the real life figure.
Been my experience with 15 to 20 foot daysailers that the bolt ropes,
for all practical purposes, don't stretch much. Maybe an inch or two.
Not six or seven feet.
