I mange år har Høj Jensen Sails eksperimenteret med sejldesign indenfor netop denne klasse.
Eksperimenterne har gjort, at vi nu producerer nogen af verdens hurtigste sejl til denne bådklasse
RIG and MAST
The distance between the stern(back) of the boat and the mainsail halyard hooked in top of the mast should be 808 centimeters
Spreader Angle:
Length : 60 cm , Angle: 24 cm.
Tuning Upper and Lower Shrouds.:
| Upper Shrouds | Lower Shrouds | |
| Light Conditions | 10 | The Middle of the mast to go 5 cm to leeward |
| Medium Conditions | 18,5 | The mast should be straight |
| Heavy Conditions | 25 | The top of the mast to go 5-10 cm to leeward |
Use a Loose Tension Gauge, Type PT-1
The basic sheeting point is measured as the distance between the jibs headattachement on the boat and the middle of the sheeting block.
On DEN 136 we have the following settings:
Light air: 196 cm
Medium/heavy: 194 cm
The tension on the halyard is only pulled so the wrinkles in the luff disappear – not tighter.
The wind strengt decide which jib to use:
Light Jib 0-5 m/sek. / 0 -12 knots
Medium/Heavy Jib 5-14 m/sek. / 10 knots and upwards
Jib setting in Waves:
When you have conditions with small short waves, we move the sheetingpoint traveller 1 position forward. If the wind increases we are only moving the sheeting point traveller 1 position backwards from our basic position.
In conditions with bigger waves we use the same philosophy. It is essential for the sharpe of the jib that you don´t go to much backwards or forward to your basic position to obtain correct twist.
On Upwind courses in wawes it is better to ease a little on the sheet instead of moving the traveller.
TRIMMING THE MAINSAIL:
The trim of the mainsail ic the critical point of the Yngling´s basic trim. If the trim is wrong you will loose speed and height. The mainsail is designed to close more in the leech when you sheet hard. Due to this concept you will have more preassure on the helm but also a better height.
The outhaul on the boom has following settings:
| Wind Strength | Smooth water | Waves |
| 1-3 m/sek | 5 cm from the black band | 5 cm from the black band |
| 4-10 m/sek | stretched out to the black band | 3 cm from the black band |
| 10 m/sek and up | streched out to the black band | streched out to the black band |
The backstay function is to open the top of the mainsail and to obtain the correct balance in the boat – if the boats will go to much to the windward, just pull the backstay until it is neutral. If you pull to much in the backstay you will loose height.
The mainsails traveller decides the twist of the mainsail. In light conditions the traveller position is a bit windward from the center of the boat. In medium and heavier conditions we keep the travveller in the center of the boat and decides the twist by using the backstay and the tension of the mainsheet.
The Cunningham is only used in medium and heavy conditions to move the sharpe forwards and open the mainsail.
When you reach or go downwind it is very important that the spinnaker pole is in a horizontal position or 10 cm above horizontal. Use a loose trimming of the sheet, this makes the spinnaker to fly in front of the boat and forestay. The foot of the spinnaker may not ever touch the forestay.
On the reach the spinnaker pole should be kept in a good distance from the forestay:
Light Conditions : 30 cm distance
Medium/Heavy Conditions: 50 cm distance
Have a pleasant sailling.
