SAIL SIZE VS SAILOR WEIGHT, REV 3/27

Post by DBlackm » Thu, 28 Mar 1996 04:00:00


The fairly large response to recent "Big Sailor?" posting inspires me to
try Sail Size versus Body Weight questionnaire again.  Please post for all
to see.  I'll post summaries of area/weight ratios from time to time.  

WIND RANGE                                    IDEAL SAIL SIZE
mph            knots         km/hr                 sq meter

35+            30+            56+              =          
20-35        17-30        32-56          =
15-20        13-17        24-32          =
10-15          9-13        16-24          =
  7-10          6-9          11-16          =
  5-7            4-6            6-11          =

Weight =         kg ==         lbs
Height =         cm ==         in
     Age =
Gender (M/F): (  )
Skill (x): Novice (  ),  Intermediate (  ),  Expert (  )
Outhaul Control Underway (Y/N): (  )
Downhaul Control Underway (Y/N): (  )

As long as we're redoing old topics, I guess I should remind
folks that this type of analysis is useless unless location is
specified.  It is fact that you will use a bigger sail in
thinner air (due to altitude and somewhat to temperature).  As
an example, at altitude=3500 ft (most lakes in NM), I would
sail a 7.5 until the wind was over 20-25 knots.  At sea
level--same weight, skill, etc.--I would be on a 4.7, perhaps
even a 4.5.

I know this is a topic of interest the world 'round (what'cha
riggin' there, buddy?), but local observations will provide a
much more useable database.

  Another factor (besides altitude and air temp) is fresh water vs.
salt water.  You will plane sooner in salt water due to the extra
bouyancy, so you can usually get away w/ a slightly smaller sail
compared to the same conditions on fresh water.

There are a lot of people that could use a 'sea level' version of this chart.
I've been tryig to come up with a formula, with no luck.
Something on the order of   28knots/185lbs = 4.7sqmeters. BINGO!
