Winning in the
Welcome to the fun world of Santana 20 sailing. This
tuning guide’s purpose is to help you set up your boat properly and to
provide a tuning reference. Boats vary as do sailing styles, conditions and
sailors. Please use this guide as a base and modify it to fit your style and
what you find to be fast for your boat. If you have any questions or comments,
please call or e-mail us at the Ullman loft. We will be happy to assist you
and hear your tuning ideas.
The goal here is to have a boat that is fast, easy to
sail and will not fail. Make sure the keel, rudder and bottom are smooth and
fair. This will ensure good underwater flow. Set up the deck layout so it is
comfortable, functional and as simple as possible. This will
eliminate broken or poorly placed hardware hindering the crew. This is
very important so the crew can concentrate on the race and not the boat. The
next item is to make sure the mast and rigging are in good working order and
are as light, clean and streamlined as possible. This will prevent failure and
increase speed. The final item is to have sails that are of current designs
and not so worn that their designed shape is no longer functional.
The goal of rig tuning is to set the mast up so the
mast is at the proper rake to balance the helm, is centered in the boat and is
set for the current wind and wave conditions. To set the rake, tie a metal
tape measure to the main halyard, not the shackle, and raise it till it is two
blocked. Pull on enough backstay tension so the forestay is just tight,
without slack. Measure to the center of the transom where the hull and the
transom intersect near the water line. This rake number is 31 feet. This rake
can be adjusted with the forestay turnbuckle.
Once the rake is set, the next project is to center
the mast in the boat. Place a mark on both rails, equidistant from the tack
fitting, about 10” forward of the chainplates. This is a reference mark for
centering the mast. Hoist the tape measure on the spinnaker halyard till it is
two blocked. Measure to each reference mark and adjust the upper shroud
turnbuckles till the measurement number is the same.
After the mast is centered, sight up the mast track
on the aft side of the mast and adjust the lower shrouds till the middle of
the mast is in column with the mast tip. The mast should now be centered and
straight. The next step is to use a Loos Model A tension gauge to measure the
shroud tensions. Set the shroud tensions to the following numbers; Upper
Shrouds: 33 (320 lbs.), Lower Shrouds: 35. The adjustable aft lower tension
should be set so the tensions are the same on both sides of the boat and when
they are in their maximum aft position the mast has 3-4” of inverse
pre-bend, approximately 11 on the tension guage. Go sailing and site up the
mast for the final rig tune. The mast tip should remain centered on both tacks
and adjust the lower shroud tension so the mast is straight and remains in
column at the spreaders on both tacks.
Light Air: 0-5
The goal in these conditions is to keep the boat
moving as fast as possible at all times. Speed is more important than
pointing. Set the adjustable aft lower shrouds so the mast is perfectly
straight with a slight bit of backstay tension. Trim the mainsheet till the
top batten hooks 5 degrees to weather of centerline and then pull enough
backstay to twist the top batten till it is parallel with the boom. Set the
traveler so the boom is on the centerline of the boat and there should be no
boom vang tension in these conditions. Ease the outhaul 1-2” from its
maximum tight setting, 1” in flat water and 2” in choppy water. Set the
cunningham with slight horizontal wrinkles along the luff of the main. Adjust
the traveler and the mainsheet to keep the boat moving fast at all times.
Light to Medium
Air: 6-12 Knots
These are efficient and maximum power conditions. The
boat should be sailed flat and powered up to maximize speed and pointing.
Tension the aft lowers to invert the mast 1-2”. Set the mainsheet and
backstay the same way as above. Set the cunningham so it is max loose like
above. Play the traveler in the puffs and lulls to keep the boat flat. The
crew should hike hard in the puffs!
Medium to Heavy
Air: 13-18 Knots
The Santana begins to become overpowered in these
conditions and the goal becomes to keep the boat flat and reduce leeway. Set
the aft lowers with 3-4” of inverse bend. Trim the main really hard and
tighten the backstay till the top batten twists 10-15 degrees from parallel to
the boom. Tighten the outhaul to its maximum setting and tighten the
cunningham to remove all luff wrinkles. Take all of the slack out of the boom
vang to hold down the boom. Play the traveler to keep the boat flat and hike!
Heavy Air: 19+
As above, the goal is to keep the boat on its feet
and to reduce leeway. The mainsail should be as flat as possible. Set the aft
lowers to their maximum setting of 4” of inverse bend. Set the mainsheet and
backstay with 15-20 degrees of twist. The outhaul is set at maximum tension
and the cunningham is tight. Tighten the boom vang to flatten the bottom of
the main and keep the leech in control. Drop the traveler to keep the boat as
flat as possible and hike!
The goal for downwind main trim is a full sail and to
keep it on the verge of luffing at all times. Ease the aft lowers all the way
forward and ease the backstay so the mast is raked forward. Ease the outhaul
just enough to open up the foot, but not so much to loose projected area,
about 2-3”. Ease the cunningham all of the way off and play the vang so the
top batten is parallel to the boom. Play the mainsheet constantly to keep the
Light Air: 0-5
The goal in such light air is boat speed, keep it
moving forward. Set the genoa halyard so the luff is just smooth to provide a
wider steering groove. The foot of the genoa is trimmed 3-4” from the shroud
turnbuckles and the genoa leech is trimmed 2-3” from the spreader tip. Set
the leads to achieve this set up. Make sure the leech and foot lines are
completely eased. Trim the sheet in the puffs and ease in the lulls.
Light to Medium
Air: 6-12 Knots
These conditions are maximum power and pointing
conditions. Ease the halyard so there are slight luff wrinkles to increase
pointing. Set the leads so the genoa foot is 1-2” from the shroud turnbuckle
and the leech is 2-3” from the spreader tip. Trim the sheet in the puffs and
ease it in the lulls.
Medium to Heavy
Air: 13-18 Knots
These conditions are approaching the top of the
genoa’s effective range. Tighten the halyard to move the draft forward and
flatten the upper leech. Set the leads so the foot is tight against the shroud
turnbuckles and the leech is 4-6” from the spreader tip. Play the sheet to
keep the boat flat. In the big puffs, easing the sheet a couple of inches is
more effective than luffing the mainsail. Just remember to trim it back in as
soon as the puff ends.
For most crews this is small jib wind. The only
reason to have the genoa up is if the waves are larger than the wind speed and
if your crew weight is very heavy. If this is the case, set it up as above. We
recommend using the new inboard class jib tracks for the small jib. The
tighter sheeting angle and smaller jib increases pointing and improves crew
work. These two items far out weigh the small loss in sail size of the old
style 110% jibs. Tighten the jib halyard just enough to remove the wrinkles.
Set the leads so the top telltales break slightly before the bottom telltales.
You can also use the leech battens as a guide. The top batten should twist
open 5-10 degrees and the middle batten should be twisted 0-5 degrees. Place
tape marks on the spreaders to use as a trim reference to line the leech of
the jib with. Trim the jib between 3-5” in from the outboard end of the
spreader. If the water is rough and the wind is at the bottom of the jib
range, you may have to power up the mainsail to keep the boat moving fast.
The Santana is a blast to sail downwind and rewards
its crew for good spinnaker trim and crew work. The halyard should be raised
as high as possible to stabilize the spinnaker and increase projected area.
Play the pole height and trim constantly. Set the pole height so the spinnaker
curls on the luff just above the half-height. This is in the top third where
the top of the horizontal panel meets the bottom of the radial panels. If the
pole is too high, the curl will be too low in the spinnaker and if the pole is
too low the curl will be too high in the spinnaker. It is not as important,
but if it is easy, adjust the inboard end of the pole to keep the pole 90
degrees to the mast. Play the guy and the sheet to keep the spinnaker on the
verge of collapsing with a slight luff curl. Remember, an undertrimmed
spinnaker is faster than an overtrimmed spinnaker.
The trimmer and the skipper should be in constant
communication while talking about wind pressure in the spinnaker. In the
puffs, the skipper bears off and the trimmer squares the pole back and eases
the sheet. As the pressure eases or the wind lightens, the skipper heads up
and the trimmer eases the pole forward while trimming the sheet. This should
be a constant “S” course to maximize VMG downwind. The foredeck crew
should be looking aft and helping the skipper keep the boat in the most wind
velocity and clear air.
We recommend sailing with a combined crew weight of
490-600 lbs. The crew should sit as close together as possible. This
concentrates the weight and reduces the pitching of the boat. The skipper
should straddle the traveler bar and use it to hook his/her feet under it for
balance. The middle and forward crew should sit together just forward of the
skipper at the widest part of the boat. They should hike with their legs over
the side when on a tack for a long time and face in during close quarters or
when tacking a lot. Use your crew weight to roll tack the boat. In light air,
especially in waves, it is fast to have the foredeck crew sit below deck to
lower the weight, reduce windage and increase the visibility of the skipper.
The skipper should sit wherever he/she is comfortable
and can see, but near the traveler bar. The trimmer needs to be to weather to
see the spinnaker. The foredeck sits on the leeward side just aft of the cabin
and moves side to side and fore and aft to keep the boat balanced. In light
air, the foredeck can stand in the companionway. Use your crew weight to steer
the boat to reduce rudder movement. Heel to leeward to head up and to weather
to bear off. A roll to weather in the jibe helps steer the boat and rotate the
The Santana is a crew sensitive boat. Practice and
good crew work produce good race results and make sailing more fun.
The skipper’s job is to steer the boat as fast as
possible at all times. The skipper is responsible for main trim, the backstay,
traveler and calling the boom vang and outhaul adjustments. The Ullman
mainsail has a spreader window in the luff of the main so the skipper can call
the distance the genoa leech is from the spreader tip. The skipper should help
with strategy before the start and leave the tactics to the crew during the
race except for the close quarter boat tactics and mark roundings.
The upwind job is to help with tactics and call boat
speed relative to other boats. During tacks, he/she trims in the headsail and
hands it off to the forward crew to cross sheet on the windward winch. The
middle crew can sometimes help the skipper with the backstay adjustment.
Downwind the middle crew trims the spinnaker and does the twings in the jibes.
On the spinnaker douse, he/she releases the spinnaker halyard and trims the
headsail around the leeward mark.
The upwind job is to call puffs, waves and crossing
situations with other boats. He/she also fine tunes the headsail sheet after
the tacks, adjusts the boom vang, outhaul, cunningham and the aft lower
shrouds. At mark roundings he/she must set the pole, hoist the spinnaker, stow
the pole and gather the spinnaker. The downwind job is to jibe the pole and
keep the boat in the most velocity on the race course. The foredeck job is the
hardest on the boat and requires the most practice and crew support. The
better you get at it the better your boat handling will be. This will lead to
better results and give you the pleasure of passing people at mark roundings.
The key to this tuning guide is not just memorizing
these settings and recommendations, but understanding how they work and how
they influence each other. The goal is to be able to feel that something is
wrong and having the knowledge to quickly fix the problem to keep the boat
moving fast. We design the Ullman sails to be easy to trim and very forgiving
so you can concentrate on race tactics and strategy instead of sail trim. If
you have any further questions or would like to order new sails please call
Ullman Sails and ask for Charlie Ogletree in the One Design department.
