Editing
All values which define the size of the sail can be edited. These values are bold and black.
Scale: determines visual size of sail plan. Smaller values give bigger size. Values increase automatically if too small a value is selected. Note that the scale is only able to be edited on the main sail and the jib is changed to the same value. This enables the two pages to be printed and matched to see what the rig looks like.
Total Luff: is the measurement between the mast bands (luff of sail)
Foot: is the perpendicular foot measurement.
Foot Height: determines the slope of the bottom of the sail and hence the slope of the boom supporting it.
Z, Y, X: produce extra width at each of measurement points and determine the shape of the leech. (The free values - 0 in this image - will default to the allowed free values if the rig is for a marblehead)
The Sail Type: (Main in this example) cannot be edited.
Description
The description is also able to be edited. This is the top value '10R No1' and is made available for editing by double clicking it. Each description must be unique but it makes sense to use a pattern for naming to make it easier to find and organise rigs.
Yacht Type
The name given to the type of yacht type (Ten Rater) on the image is also able to be edited by clicking on the green sign 'Click here to edit 'Yacht Type'. Any change made to the yacht type is reflected in all other rigs involving that yacht type.
Editing and Current Rig
Once editing has begun then the only available rig to view is the one displayed and the drop down box (lower 10R No1) is greyed out and not active. Both the main and jib are available to be edited to see the effects of changes such as the total Sail area or Main/Jib area ratio. Switch between them by using the 'Show' jib button
Saving Record
The 'Save Record - Y/N' button is active once a rig has been edited and should be clicked once editing has finished. The edits may may then be saved or discarded returning the information back to the original values. This allows the values to be varied to see their effects without committing them.
Areas and Ratios
Note that the sail areas and area ratios are not editable as they are calculated from the sails in that rig. For a Marblehead yacht the sail area ignores the added roach allowance in the rules and simple calculates the triangulated area from the luff and foot. Any additional extra width added via the 'X', 'Y' or 'Z' values will add area though. All other rigs base the area on the sail as they show with no free values and make an approximation of the real area which will need checking by the appropriate rules that apply to that yacht type.
