approxamate planning - sail size - wind speed question ??
dan sawyer
I am new and am just moving to a 'short board'. I am using a
Pro AM that is about 9 feet and I weigh about 220. What
are the minimum wind ranges to initiate a plan with:
4.7 flater Hurricane
5.2 fuller Hurricane
5.8 fuller Hurricane
I tried today with the 5.2 and about 14 mph winds. That was
a full stop effort to even get close. The board would move
enough to be manouverable but it was definatly a stern
dragging ride. This was my first attempt with a shorter
board from a transition board so I am certainly not sailing
optimally.
Thanks again in advance,
Dan Sawyer

What can I say - "power up, dude!". 14mph equals 12 knots. This is WAY too
little wind for any of these sails. I am 205lb myself and I find 5.8
adequate for 20-25kt wind. If it drops anywhere below 20kt I would go for
6.4 or so, but even this doesn't seem comfortable for winds under 15kt.
Given your weight I would guess that 20+ kt wind would be fine for your 5.8.

Not familiar with your board or sails, what is the volume on it?
Unfortunately, at your weight I would say you will be needing something around
25mph on the 5.8 to get really powered up. Maybe a little less since you are a
beginner. I know my definition of "powered up" has changed since I was a
beginner.
I will also point out that you have 3 sails that are too closely grouped in
size. A guy your size should be packing a 7.5 or 8.0, then maybe a 6 and 5.0
hurricane sail.

really powered up but it's tough to get going dues to the weight of the
board and it's design characteristics. Try at least your 5.8 in 14mph. See
how that goes.

Do you mean the O'Brien Pro Am - (that is the board I learned to shortboard
on - bought it for $250, sold it two years later for $200.00) Heavy as a
truck, flat as hell rocker lines.
You need more sail. Lots more sail. I used to frequently sail my Pro Am
with a 7.5 M sail. It was not easy to get going, but once you get enough
water flowing over the fin, it is do-able.
I would really suggest:
a) more wind
b) bigger sail
c) newer board.

Huricane, but I want to add this:
I was 145-150 lbs. when I got my fuit shortboard. I took it out in
about 14 knots with a 7.5 and struggled to plane. A year or two later
and 10 lbs. heavier, I was planing in the same wind with a 5.5. Your
planing threshold will lower as your tehnique improves, but you are
definitely underpowered at the moment. I would think that, given your
weight, you might need 18 knots or so and a 7.5 to plane on that
board.

The consensus responce was more sail. Yesterday in the low
teens range the rig was definatly under powered however a
couple of days ago on a different board (older 10' 6" F2
Comet) I planned easily with 4.7 with wind in the low 20's.
Can I assume I could plan on the O'Brien Pro AM 9' 4" with a
4.7 in low 20's as well??
What is the range of a single sail. If a sail plans nicly at
say 20 when would it become overpowered??
Again, thank you all,

I am an intermediate who recently moved onto a short board. I can affer
this much based on my little experience: Like everyone else said, you are
way underpowered. I am 155lbs, 273 board, recently got a new 7.2 sail (by
new I mean newer model) and I easily use it in 18+ knots "inconsistent"
conditions. Why a big sail? It helps me make it thru lulls in inconsistent
gusty/lull conditions. The new sails have an increadible wide range that
depending how you rig it (down/out haul), a 7.2 sail can be used like a
5.x-7.x. Please note that I am NOT suggesting that a 7.x sail can replace a
5.x one - not at all. I am saying that if I don't have the perfect sail
size for a given condition, I'd rather be in a "controlled" over-powered
situation (very down-hauled bigger sail) than an under-powered one.
At least that has been my personal experience. I am sure others may agree
or correct me on this.

need at least a 5.8 to plane up in the low 20s. I weight 170 Lbs and I would
use a 5.7 in those conditions.
As to your range question, it depends on the size and type of sail. Bigger sails
tend to have more range (which has more to do with the square increase in force
per linear increase in wind speed). Some big race sails have a 15 MPH range,
i.e. you can run them from 10 to 25 MPH. Small sails can't accomodate this range
i.e. a 3.2 will be pretty good at 40 MPH but not 55 MPH..
A typical full coverage quiver for me is 8.5, 6.5, 5.5, 4.7, 4.2, 3.7, 3.2.
At 55 MPH, I really need a 2.7, but I just don't see those conditions very often.
Much of this depends on the board, water conditions, and rider ability as well.
For me a sail which planes nicely at 20 MPH will start feeling big at 27 MPH and
be
grossly overpowered at 30 MPH.
Does that help?

Depending on the board width and fin, you should be running 8.5 to 9.0 in 14
mph.

To avoid getting into a very long essay, and just sum it up,
a long board is an entirely different beast than a short board. It's (almost)
the difference between walking on 2 foot deep snow with snow shoes versus plain
boots .
I am sure that you're definitely moving faster and things are getting fun but I
would doubt that the board is on a full plane, or maybe you're underestimating
the speed of the wind?
To give you a little frame of reference, I'm 140 lbs and I start using a 5.0 in
the low 20's on a short board. In the same conditions, some sailors I know that
are closer to your weight are using 6.5.

liter board. These are my sails and the general windspeeds in which I
rig them up. Sometimes the water conditions, flat or choppy, and the
gusty nature of the wind alters this, but this is generally how it
works out for me, after alittle tweaking of the trim. Perhaps this
will be of some help to you, since you are only 10-15 lbs. more than
I.
4.7m2, 28-31cm fin, 25-33kts, 8'8" 85 liter board.
5.5m2, 31cm fin, 20-25kts, 23kts+, I swicth to a 8'8" 85 liter board
6.0m2, 31-33cm fin, 17-22kts
7.0m2, 34cm fin, 14-18kts
7.5m2, 48cm fin, 13-17kts on a 9'9 board

But am in Freshwater in the Gorge. I use a 110 litre slalom. It is always
gusty. I included in parentheses fin size for more constant winds and salt
water (Maui especially. I prefer our SR-6b CG-10 CNC.
6.3 : 34 and 36 (32 and 34)
7.0: 36 and 38 (34 and 36)
7.8: 38 and 42 (36 and 38)
If you are heavier and on smaller board different fins will make a huge
difference.
It also depends on conditions. Note Dan is my wieght but has a smaller board
AND smaller tail, he might be mostly in salt water, not sure. For either of us
all other factors equal, fin choice will also change between 101 and 110 litres
(plus mine is a 200s, 14" tail)
Once you are dialed slalom sailing is a rush. Also if you are much heavier,
different designs and bigger sails may work better for you, especially if it is
gusty and the lighter end of the wind range
