For example, if a cog is in waters without a
current and a wind of 100 feet per round that moves
from the south to the north, then since a cog has
40% Wind Potential, the cog has the potential to
capture 40% of the wind’s 100 feet per round. Since
40% of 100 is 40, the cog may move at 40 feet per
round if the cog is moving to the north. However,
the sailor in charge of the sails rolls a 27 for their
Sailing skill check. In this case, 27 x 3 = 81, and
81% of 40 is 32. Therefore, a cog traveling north
moves at 32 feet per round in calm waters with a
north wind of 100 feet per round when its sailor
rolls an 27 for their skill ckeck.

Wind Duration
No character ever truly knows which way
the wind will blow. For this reason, once a direction
of wind is determined, its duration is also important.
To determine the duration of the current wind,
roll 1d100 and consult the table below:
Roll Wind

01-453d20minutes 46-901d20hours 91-1001d20days Once the duration of the current wind expires,
a new direction and strength must be determined.
