Evolution II Rig - User Manual

Attention!

Some Evolution II Rigs are in circulation in which the mast extension print has been wrongly positioned. See below image. If your mast extension matches version A, it is correct. You can follow the normal rigging instructions and read the extension specs on the sail. If your mast extension matches version B, you have to use 5cm more extension than instructed on the sail.

This step-by-step guide shows how to assemble and fine-tune your Unifiber Evolution II Rig.

Contents:

• Sail
• Mast - two parts
• Boom
• Mast extension with downhaul rope
• Uphaul string
• Batten tensioner key

Rigging:

1. Unpack all rig components and lay them out.

2. Unroll the sail downwind on a flat and gentle surface, like grass or sand.

3. Set the boom and mast extension to the required lengths as indicated on the sail.

4. Slide the mast up the luff sleeve.

5. Important! Ensure that the mast tip is completely inserted in the head of the sail. And check by feel that the mast parts are properly slotted together at the join.

6. Put the mast extension in the mast. Thread the rope through the sail’s foot eyelet, around one pulley, one more time through the eyelet and finally through the cleat of the mast extension, as shown in the picture:

7. Place your foot against the base of the mast extension and pull the downhaul line to tension the sail. When there is 5 cm (2 inches) between the eyelet and the pulley, the tension is within the recommended range.

Tip: use the Unifiber Downhaul Tool to easily tension the downhaul rope without hurting your hands.

8. Check that the sail battens are sufficiently pulled away from the mast. If it is hard to push the battens to the other side of the mast, the sail requires more downhaul tension.

9. Attach the boom’s front end to the mast at about shoulder height. Make sure the clamp is firm and there is no play between the boom and the mast. If necessary, adjust the rope length to loosen or tighten the clamp.

10. Thread the outhaul rope through the clew eyelet of the sail. Apply light tension, as in the picture below.

11. Stow the excess line by tying around the boom tube and mast base.

12. When the sail is first rigged it will be necessary to tension the sail battens. Turn the tensioner key clockwise until the wrinkles around the batten pocket disappear. Do not over tension.

Left: not enough batten tension    Right: batten tension is correct

13. Attach the non-elastic end of the uphaul to the small rope on the front end of the boom. Loop the elasticated end around the mast base.

You’re ready to sail!

Derigging:

Follow the rigging steps in reverse order. You can leave the battens tensioned and keep the uphaul line attached to the boom.

Fine-tuning:

When you feel that you need more power, you can release some outhaul tension so that the sail has a deeper profile. In stronger winds, or if the sail handling feels heavy, you can increase the outhaul tension to flatten the sail. Too much outhaul tension will make the sail feel nervous and difficult to control.

Maintenance:

Always rig the sail on a gentle surface (grass or sand) and avoid rocks or asphalt, to prevent scratching or damaging your gear.

When your gear is not being used keep it out of direct sunlight. Over-exposure to direct sunlight will shorten the life of the sail.

When your sail is damaged by a puncture wound or small tear, fix it immediately. Take it to a professional repair shop; or - for a temporary fix - use Dacron tape or clear monofilm tape as appropriate. Even duct tape is an option if nothing else is available. If you continue to use a sail that is damaged, the tear may spread and become much more difficult to repair.

We recommend letting the sail dry before putting it in its bag. Store the sail in a well-ventilated place.
