Additional things to add to the log-book

If weather conditions permit... take a digital camera along and when the trim seems just perfect on a beat or on a run, take a shot from the center of the jib-foot looking up (spinnaker if it's a run) to the head and from the center of the main-foot looking up to the head. Try to get the ends of the trim stripes at the luff and leach in the frame, so that we can process the photo with the UKSails Accumeasure (tm) program.
Log the following with the picture:

• Date
• Sail
• Apparent Windspeed
• Apparent wind angle
• Halyard tension setting
• Backstay tension
• Forestay length.

Store the images in the archive directory of the boat laptop.
