The J/111 is a relatively light boat which makes it very receptive to positive trimming. It is imperative to have the sail trim spot on but

also the fore and aft weight trim correct and whichever team does this the best will be rewarded with the best boat speed.

Having the weight in the right place is crucial. In simple terms, keep the weight out of the back of the boat both up and downwind and hike very hard to see visible gains made on the water.

Up to 10 kts the J/111 is always looking for more power so keep the sails powered up, focus on building speed efficiently out of transitions (tacks, gybes, ducks and mark roundings) and don’t over trim or you can easily kill the speed.

Tracking the Rig Tune Once the rig is tuned to our North Sails BASE setting (see J/111 Tuning Guide on page 5) you should be aiming to, at the bare minimum, change the forestay for the prevailing conditions each day. The top teams will adjust this between races. This will make a huge difference to your sail setup and ultimately your boat speed around the track. In heavy air winding the forestay shorter will enable you to get enough backstay on and bend the rig efficiently and in light air lengthening it will

enable you to keep depth in the sails to keep

the power on.

Take your rig tune seriously. Keep

whoever adjusts the rig

the same from the beginning to the end and you will be far more accurate all season long. It is one item on our list we can get right before we leave the dock.

Equipment Requirements

■■ Loos Gauge RT-10M (V1 and D1 shrouds)

■■ Loos Gauge PT-2 (D2 shrouds)

■■ 30m (100') tape measure (forestay pin-to-pin)

■■ 5m (16') steel tape measure (mast heel)

■■ Rig spanners (adjustments)

CalibrationWe strongly recommend you calibrate every available moving piece onboard the J/111 and then take notes of which settings are fast in which conditions, this is the only way of accumulating good data for your boat and being able to repeat fast settings.

J/111 Tuning Guide


Setting Up the RigOnly once you’ve calibrated everything and recorded the data strictly can you then be confident in how to repeat a fast setting.

All of the settings are crucial at the top level but a bare minimum you should create a cheat sheet for different wind strengths with the following information:

■ Jib halyard tension ■ In-hauler setting ■ Backstay position ■ Jib sheet location■ Jib car position ■ Spreader mark number

Mast Step position Measure 44 cm (1.44') from bulkhead to forward face of mast (not including base trim).

Headstay Set headstay length (center of upper pin to center of lower pin = 15.13 m [49.64']).

J/111 Tuning Guide


J/111 Tuning GuideThis guide is based on the experience of a number of North Sails experts, owners of J/111s and their trimmers. It is ‘just’ a guide. We all know ours is the most complicated sport in the world and any number of

factors can affect our performance. Use these numbers as your starting point from which you can improve, use your own calibrations and settings to give you and your team an edge going forward.

J/111 Tuning Guide


Mainsail Trim AdjustmentsTraveller Upwind, keep the boom on center line using the traveller.

Backstay This controls mainsail depth. As the breeze builds, use more backstay to flatten the mainsail, use less backstay in choppy seas to help power up the boat.

If you have too much backstay you will see over-bend creases in the mainsail from clew to luff in the lower third of the mainsail. Ease the backstay off until they are just not showing.

If you can’t flatten the mainsail enough with backstay because the ram is maxed out then you have the wrong rig tune and you should shorten the forestay.

Cunningham Only use cunningham to de-power the mainsail in over 16 kts of windspeed. Do not use it to take out small horizontal creases in the luff, if you are doing that then your main halyard has slipped.

Outhaul Controls depth in base of mainsail. Flatter water = tighter outhaul. Chop and waves = looser outhaul. In 10+ kts on the J/111 the mainsail foot should be just tight along the top of the boom, this will need extra tension as the breeze increases. In under 10 kts upwind you can ease the outhaul but no more than a fist-width gap between the boom and mainsail at the mid-point.

Headstay Adjustment

To make faster adjustments we suggest changing the original bolts to something easier to remove. Above: 2" eye bolts are used.

1. Remove the 2 bottom drum bolts.

2. Remove the 3 foil screws.

3. Remove the pre-feeder and let the foil gently rest on top of the upper roller swivel.

Backstay Use0 - 4 kts 0 - 25% backstay

4 - 8 kts 25 - 50% backstay

8 - 12 kts 50 - 80% backstay

12 - 16 kts 80 - 90% backstay

16+ kts + / - Max backstay

Traveller is a coarse control for heel angle and twist control.

The extent of traveller movement shown at left.

Remove the 3 screws that hold the pre-feeder and foil firmly in place. Take care, these screws can easily fall in the water!

After the screws and pre-feeder have been removed the foil will drop down to the top of the headswivel which must be at the tack for this adjustment.

J/111 Tuning Guide


4. Using a forward halyard attached to the jib tack fitting slowly raise the drum and entire foil above the trunbuckle.

5. Turn the turnbuckle the number of turns you require.

6. Insert and tighten new zip-ties.

7. Lower the furling unit back into place and reverse steps 1, 2 and 3.

Take care not to drop the 2 plastic inserts overboard. These are washers that slide between the drum base and the flange on the headstay stem fitting.

This red line is the maximum height you need to raise the bottom of the drum. Cut the headfoil to this length when hoisted like this with the turnbuckle at it’s shortest adjustment length.

It is necessary to use vice-grips on the barrel of the headstay. There are no flat spots on the barrel for a wrench.

Use zip-ties to stop the turnbuckle from spinning. This is quicker for the adjustment process.

J/111 Tuning Guide


Jib TrimJib Sheet Coarse control for leech tension and slot shape.

Jib Halyard Sets the sail depth and draft position. Increase halyard tension incrementally as the breeze increases.

Jib Car Controls sheeting angle and depth in the base. Car forward in light air to add depth and power, car aft in heavy air for flatter base to reduce power.

In-Hauler Used in conjunction with the jib car for slot shape and power control.

Backstay Sets forestay sag to control depth in the entry of the jib.

Spreader MarksWe recommend that you put marks on the spreaders so that you can repeat the trim settings easily.

White tape on the spreaders should be in the following locations:

Top Spreader■ 710 mm (2.33') outboard

from mast.

Bottom Spreader

■ 860 mm (2.82') outboard from mast.

■ 1060 mm (3.48') outboard from mast.

In-Hauler and Jib Car Settings

If the helm is struggling to build speed because of the sea-state you need to ease the in-hauler outboard to allow the bow to come down.

In very flat water you can in-haul tighter for increased pointing. In heavy air, if you see too much

backwind in the mainsail, ease the in-hauler outboard.

If you have overstood the windward mark, your first control to ease is the in-hauler so the helm can be fast in a bow-down mode.

Jib Car SettingsCode 1 =

LM4950 mm (16.24’)

from tack

Code 2 = MH

5050 mm (16.57’)from tack

Code 3.5 = HWJ

4750 mm (15.58’)from tack

In-Hauler SettingsCode 1 = LM 600 mm (1.97’) from centerline (inside handrail)

Code 2 = MH 660 mm (2.17’) from centerline (at handrail)

Code 3.5 = HWJ 700 mm (2.30’) from centerline (outside handrail)
