[alberg30] Which Winches.

[Guy Lalonde]

From: Guy Lalonde <lalondegc at videotron.ca>

For the most part, the winch numbers for Harken, Lewmar & Andersen represent
their power ratio. I know Barient winch numbers do not as well as some
others. I've seen used Barient 22s advertised to be equivalent to Lewmar
40s. If unsure about what your winch number represents, the power ratio can
be calculated this way.

First determine the gearing ratio of your winch. Turn the winch handle one
turn and determine how many turns are made by the body of the winch. If 6.5
turns of the body are generated by one turn of the winch handle, then gear
ratio is 6.5 to 1. If it is a one to one relationship then your winch is not
geared or for purposes of power ratio calculation it is 1 to 1.

Then calculate the power ratio:

(gear ratio    multiplied by    winch handle length in inches)    divided by
radius of the drum in inches

the drum being the part where the sheet winds around the winch

If your gearing ratio is 6.5 to 1, your winch handle is 10 inches long and
the radius of you drum is 2 inches then

(6.5 x 10) / 2  = 32.5 is your power ratio

If your winch is 2 speed, determine the gearing ratio when turning in the
other direction and redo the calculation.
