SAIL MAINTENANCE
• Let your sail dry before de-rigging.
• Shake the sand off before rolling up your sail at the beach, as this will extend
your sail’s life considerably. Rinse the sail with fresh water occasionally, including
inside the mast sleeve, to avoid
salt and sand buildup.
• Avoid rigging on hard or abrasive
surfaces.
• If left rigged all-day or overnight,
release the outhaul and
downhaul.
• Store your rigged sail out of
direct sunlight. UV degrades
monofilm.
• To prevent creases in the
monofilm, roll your sail on the
tube it came on, or roll it tightly
and store it where it won’t get
flattened.
• Repair tears promptly through a
qualified sail repairperson. Make
temporary repairs to the monofilm
with Mylar packing tape or a
sticker on both sides.
• Do not use solvents for cleaning
near seams, as this will dissolve
the seam tape adhesives. Use
water and mild soap.
• When on the beach, secure your
sail from blowing away.
• Avoid getting sand or dirt inside the mast
sleeve and batten pockets. This reduces sail
performance by increasing friction and wear
on the mast.
• Loosen the batten tension if you are not
going to use the sail for an extended period.

Welcome to the Revolution.
We are confident that you will be
thrilled with your new Revolution
SR4 in any type of water or wind
conditions, from bump & jump
blasting to down-the-line wave
sailing. The Revolution SR4 is
highly adjustable, so you can easily
tune the rig balance to your sailing
style and the conditions you sail in. Follow this rigging guide to
maximize your windsurfing experience!
The Revolution SR4 has new features that make it easier to assemble
and use:
• New streamlined SBT’s (Screw Batten Tensioners) for faster rigging
and a cleaner leech - set it and forget it.
• A mast sleeve that’s wider and tapers less, making it easier to insert
a mast. This extra sleeve width also keeps the foot batten from hanging
up on the mast in transitions and makes rotation smoother.

REVOLUTION SR4 - specifications
dimensions mast requirement
FIRST TIME RIGGING
USE THE RIGHT MAST
One of the most important parts of your equipment is the mast, and its stiffness.
The mast acts quite literally as the backbone of the rig and it’s extremely
important to the correct sail performance.
The mast requirements for the REVOLUTION SR4 are printed on the sailbag and
at the tack of your sail. Listed on page 1 is a broader range of mast specifications
describing the mast lengths and stiffness (IMCS #) necessary to be compatible
with the shaping and tension profile of your sail. Your mast MUST be within this
required range, regardless of the brand or model. Note that NOT all sail sizes work
on the same mast. As a rule, larger sails need longer and stiffer masts while
smaller sails require shorter and softer masts.
Two common problems are:
i) Using too long, or too stiff a mast. This restricts wind range
by over-tensioning the sail.
ii) Using too short or too soft a mast. This also restricts wind range
by insufficiently stabilizing the sail.
USE A MAST DESIGNED FOR SURF SAILING IF YOU WILL BE
SAILING IN OR NEAR BREAKING WAVES!
Note: The REVOLUTION SR4 sails are designed and balanced on specific Sailworks
masts to suit conditions typical for the “average” size sailor (140 -190 lb/63 - 86 kg).
If you are lighter than this average, or prefer a softer handling, consider using
the next mast softer or shorter listed in the specification table. Note that the luff
and boom dimensions listed are intended as a guide to rig assembly and sail trim.
Depending on the rig components you choose, these dimensions may not always
correspond exactly to the settings which are best for you. Boom length is
measured from the front of the mast at the middle of the boom opening to the
back of the clew. Luff length is measured from the top of the mast sleeve, around
the front of the mast curve to a point opposite the center of the tack grommet.
SET THE HEADCAP LENGTH
The Revolution SR4 is fitted with an adjustable headcap system. This allows for
masts longer than the sail’s luff length. Check the luff length of your sail (printed
at the tack and on the sailbag), and compare it to your mast length. If your mast is
shorter than the luff length, adjust the headcap extension strap so the headcap is
as close to the top of the mast sleeve as you can set it. If your mast is longer than
the luff length, estimate the amount of mast that will extend out the top of the
sleeve (mast length minus luff length). Adjust the strap so that the top of the
headcap is 1-2 cm shorter than this distance away from the top of the mast sleeve.

RIG ASSEMBLY
1. INSERT THE MAST
Pull the sail down the mast in sections using the tack handle and working the mast tip to the top of
the luff before pulling the tack of the sail all the way down to the base of the mast. Try to keep the
battens all rotated to the under-side of the mast. Check that the headcap is seated completely onto the
mast and that the two-piece coupling of the mast is joined properly before downhauling.
2. INSERT THE MAST BASE
Estimate the amount of mast base extension needed by subtracting your mast length from the luff length
of the sail. Your downhaul pulley system should have 6:1 purchase and enough line to make lacing easy.
Lace the downhaul line through the tack grommet. Keep the line looping in the same direction each time
you feed it through the grommet and through your base pulley. We recommend coming up through the
grommet and lacing counter clockwise through your base pulley. Try not to cross the lines, as this
increases friction and will make the downhaul harder to pull. Do not fully downhaul the sail yet - leave
the downhaul just “hand-tight”.
3. ATTACH THE BOOM
Adjust your boom to the length specified for the sail. If you are in doubt where to set the boom, attach it
at the middle of the opening and re-adjust it after the sail is fully rigged. Be careful not to attach your
boom too high in the boom opening - you must account for the sail to be downhauled further. Also be
careful not to pinch the mast sleeve under the boom clamp. Lace the outhaul through the clew grommet,
and pull the outhaul completely so the sail is flat using the recommended boom length.
4. TUNING THE DOWNHAUL
The downhaul controls the sail’s shape and performance. Discover its effect by pulling and slowly releasing
the line. Use an easy-rig or downhauling tool so the line is easier to pull hard. Watch the change in
depth and tension of the leading edge (front 1/3 of the sail), and the flattening and loosening of the
head area (upper leech) as more downhaul is pulled. Also notice the change in the angles, or twist, of
the battens; the top batten should open to leeward the furthest-called “progressive twist”. Twist is cut
into the sail, but is ultimately controlled by the downhaul tension. More downhaul induces more twist;
less downhaul allows less twist. Twist improves sail efficiency by lowering the center of effort and
making the sail easier to control.
The optimum downhaul setting gives a tight luff and a lean (not full) entry, and the leech area between the
top two battens should become loose (see Revolution SR4 Settings Chart on pg.5/6). A good reference point
is the curved leech seam between the top two battens. If the looseness stops at this line, you have the
medium or optimal downhaul setting. If the looseness falls about 5 cm short of this seam from the leech
side, you will have the minimum setting. If the looseness extends forward past the seam, you will have the
maximum setting. This looseness is normal and is necessary to allow the sail to twist open properly.
Once you’re familiar with the correct downhaul setting, re-check the headcap length vs. mast base
height. If necessary, re-adjust these so that the tack grommet sits very close to the mast base cleat, and
the amount of mast extending out the top of the mast sleeve is minimized by lowering the mast base.
5. TENSION THE SBT’S (Streamlined Batten Tensioners)
The battens are tensioned using the hex-key tool found under the
strap above the tack handle. Insert the hex-key into the cap screw
inside the SBT at the leech end of
each batten. Turn the hex-key to the
right (clockwise) to tighten. Tension
the battens JUST until the wrinkles
across the batten pockets disappear.
Look for a continuous smooth shape
to the sailcloth next to the batten
pocket (see photos). You should see
a smooth reflection, with no wrinkles in the sailcloth alongside the
battens. CAUTION: DO NOT OVER-TENSION THE BATTENS - POOR
ROTATION, EXCESSIVE FOIL DEPTH AND DAMAGE TO THE SAIL CAN
RESULT. Replace the hex-key tool back in its pocket above the tack
handle. Once the batten tension is set, it’s not necessary to adjust
it for each session. Set it, forget it!
6. BALANCING THE OUTHAUL SETTING
Release any outhaul tension and allow the sail to relax naturally. Pull the outhaul a minimum of 3.0 cm
(1 1/4") from this neutral position. Check the foil depth by pushing on the sail area under your harness
lines or standing it up in the wind. Under pressure, the sail will increase in depth as the battens pull
back from the mast. When luffing or without pressure the sail will flatten. Less outhaul will make the
sail fuller and more powerful for reaching, but it will also be harder to control when over-powered or
sailing upwind. For upwind sailing or over-powered conditions, more outhaul tension will improve
performance by making the sail flatter and tighter.
TUNING TIPS FOR CONDITIONS AND RANGE
(please refer to REVOLUTION SR4 Optimum Settings Chart pg.5/6)
CONDITIONS
• In side shore, side-off shore waves or bumpy conditions, where you need a lot of recovery
balance, you won’t want the most powerful setting. Set the downhaul a little tighter than the
optimum setting, and the sail will feel smoother, softer and more controllable over the bumpy
conditions (much like tuning the sail for stronger wind conditions, allowing the sail to twist more).
• For wave riding and pulling fat moves, where you will be sailing at some extreme reaches off
the wind, you will want to reduce the chance of getting back-winded. So, you can increase the
amount of outhaul to flatten the sail. At this setting, the batten just above the boom clears
the mast without touching it.
• On flat water, the downhaul can be eased up to give the sail more power, and you can use a
little less outhaul tension, moving the draft forward in the sail. At this setting, the batten just
above the boom should touch the mast (lean entry), but should not extend forward of it. This
will let the sail fill up with wind when under power, because the battens will have enough slack
to pull away from the mast, giving the sail a deeper foil.
WIND RANGE
• More downhaul induces more twist, which is good for overpowering conditions; less downhaul
allows less twist, which is good for light wind and makes pumping more efficient. Recognize
twist by noticing the rotation of the batten tips around the mast in the head of the sail and
the looseness in the leech between the top two battens.
• Outhaul controls the depth of the foil. Less outhaul for less wind creates more power by
allowing the sail to be fuller. In stronger winds, more outhaul will flatten the sail for more
control. For upwind sailing, or overpowered conditions, more outhaul tension will improve
performance by making the sail flatter and tighter. This setting suits a sailor who likes to
attempt transition tricks and
other slick maneuvers, allowing
the sail to luff and re-power faster.
• Whenever you increase or release
downhaul, keep in mind that
you changed the outhaul
tension, as the two are closely
inter-related.
Note: These are general reference
points to aid you in rigging your
new Revolution SR4. But, your
best test for the optimum setting
is to rig it and go sailing! Use the
above as a starting point and try
different settings until you find
what works best for you.
Experiment with over-downhauling
by about 2 1/2 cm (1"), and
releasing tension to get the
downhaul to the setting you want. 4

Q. How do I know how much downhaul to give the sail in light-wind wave sailing?
A. You don’t want to pull too much downhaul making the leech the very loose, as this is
a heavy wind setting. The ideal light wind setting should have a little tension
in the leech with a little bit of looseness near the top of the sail, with only a little
bit of outhaul. This will give the sail more foil and more power for lighter wind.
Q. How does the downhaul affect the outhaul; why do I need to adjust both?
A. When you downhaul a sail, you are essentially bending the mast into the curve of the
sail’s mast sleeve. As you pull more downhaul, the clew moves away from the mast,
increasing the boom length. As you ease off the downhaul, the clew moves towards the
mast, decreasing the boom length.
Q. What is the proper amount of batten tension?
A. The proper batten tension is just enough to get rid of any wrinkles in the batten pocket
and any waves in the monofilm adjacent to the batten pocket. If you have too much
tension on the battens they will not rotate properly. Check tension before your second
sailing session, as new sailcloth will have “set”, or stretched slightly.
Q. How do I rig my sail for bump & jump conditions?
A. For bump & jump conditions you will want to set you sail up to get the most amount of
power and twist for control in gusts and chop. To do this you can pull the downhaul to
the optimum setting noted in the chart above, and pull the outhaul just enough to give
the sail tension without getting rid of the foil or depth.
Q. What do I do if I keep getting backwinded when wave sailing?
A. You can try to flatten the sail more by pulling the outhaul and downhaul, so the batten
above the boom clears the mast. If the foil is too deep it will backwind as you change
your reaching angles on a wave. A flatter sail will be more controllable in wave sailing
but will not be as powerful to get up on a plane.
Q. My back arm gets tired and I am having a hard time sheeting in.
A. You’re overpowered, or you may need to move your harness lines back, or simply pull
some more outhaul to move the draft forward. An extreme downhaul setting and very little
outhaul moves the draft back causing you to use your back arm more to compensate.
Q. My front arm gets tired and I feel like I am going to get launched forward all the time.
A. Check your harness line balance point: when you are hooked in, see if you can lift your
hands off the boom. If the sail moves to the front or the back of the board, try moving
your lines the other way. Or try to increase your downhaul tension (moving the draft
back) and do not touch the outhaul (it automatically gets looser by pulling the
downhaul. Increasing the outhaul would move your draft forward). This is where you
can really relate the two settings and find the perfect balance.
TROUBLESHOOTING
Getting the most from your gear
• If it doesn’t feel right, it probably isn’t. A well-tuned rig should be effortless to sail. Don’t be afraid
to make changes and explore different settings.
• When you have found settings - (boom length, mast base length, boom height, mast step position,
downhaul and outhaul position)- that feel balanced, record the position of each adjustment so that
good settings are easy to repeat next session. Mark the settings with a waterproof marker right on
your equipment.
You can expand the REVOLUTION SR4’s wind range significantly by adjusting the
downhaul and outhaul. IMPORTANT: Downhaul and outhaul tension are closely
interrelated. Whenever you pull or ease the downhaul, you inversely affect the
outhaul tension, so readjustment of the outhaul may be required.
