The trimmer should keep a slight curl in the luff of the sail. Remember that an under trimmed spinnaker is much faster than an over trimmed and stalled spinnaker. Spinnaker trim needs to be constantly adjusted due to the changes in apparent wind caused by velocity changes, steering, waves and changes in boat speed. The ease of the sheet will move the driving force of the sail forward instead of healing the boat to leeward. When running, concentrate on steering your optimum down wind angle.
Good drivers are sensitive to small changes in boat speed.
When the boat is going slow, head up a little to increase boat speed. If the boat is moving fast or in a puff, bear off to ride the puff longer and use your extra boat speed to sail lower. Good communication between helmsman and trimmer is important. If you have any questions, comments or suggestions about your new Santana 20 sails, we will be glad to discuss them with you.
