Start with the boat, then describe the job. Those two choices give the sailmaker the context behind every number that follows.
Select the boat
Choose the exact model, year and rig where they are known. The configurator records Boat Model, Boat Name and LOA, and a matched boat record gives us the starting rig data for review.
If the boat has more than one rig, or has been modified, identify the version in Note. A photograph of the boat under sail is useful when the rig no longer matches the standard record.
Define the usage
The system records Usage. The useful distinction is how the sail will actually be used:
| What it tells us | |
|---|---|
| Cruising | One manageable sail with a useful working range and forgiving behaviour |
| Racing | A more tightly defined wind and angle range, often as part of a larger inventory |
| Delivery or special use | A specific job that should be described before the cloth and shape are settled |
There is no universal S1-S4 specification for symmetric spinnakers, so we do not ask you to choose one. If the sail has a defined role, describe the wind range, angles and usual crew in Note.
One sail or part of an inventory
For a boat buying one symmetric spinnaker, the normal answer is a general-purpose running sail. A racing inventory may separate light-air, general-purpose and heavier-air roles, but those roles are defined by their job rather than by a universal number.
What happens next
Once the boat and usage are set, move to Dimensions. If you already have a sail or specification that works, its dimensions are the most direct starting point.
