Compare sails by the cost of delivering the required job over their useful life. Include the complete delivered price, realistic years or sailing hours of useful shape, maintenance and repairs, handling consequences, downtime and the cost of poor fit. A cheaper sail is only better value when it meets the same brief for an acceptable period.
Define the unit of value
A club racer might compare competitive seasons; a passage boat may compare dependable offshore miles; a weekend cruiser may compare years of easy, predictable service. Choose the unit before looking at price so each proposal is evaluated against the same outcome.
Build the complete delivered cost
Include GST, freight, measurement, hardware, UV protection, battens, fitting, commissioning and likely early adjustments. Record optional items separately. An incomplete quote can appear cheaper while transferring essential costs to the owner.
Estimate useful—not merely physical—life
A sail can remain structurally intact after its shape no longer meets the brief. Estimate shape life and structural life separately, using the proposed material, construction, expected loaded hours, UV exposure and care. Treat estimates as assumptions, not guarantees.
Include ownership consequences
Weight, reefing friction, furling quality, repair access and support can affect crew workload and downtime. For remote cruising, a repairable construction and available service may carry more value than a small initial saving. Record these consequences beside the arithmetic.
Decision table
| Input | Quote A | Quote B |
|---|---|---|
| Complete delivered price | Include all required items | Include all required items |
| Expected useful shape period | State years, hours or seasons | Use the same unit |
| Likely maintenance and repairs | Estimate and document | Estimate and document |
| Support and downtime | Record local access and lead time | Record local access and lead time |
| Cost per useful period | Total divided by useful period | Compare only after assumptions align |
What to put in the brief
- Choose the useful-life unit
- Normalise every inclusion and exclusion
- Estimate loaded hours and UV exposure
- Separate shape life from structural life
- Add maintenance, repairs and downtime
- Run conservative and optimistic scenarios
Frequently asked questions
Can a sailmaker guarantee useful life?
Usually not as a fixed number because exposure, use, handling and care vary. Ask for the design assumptions and warranty terms.
Should resale value be included?
Only when realistic and material to the choice. Used custom sails often have limited fit-specific resale value.
Is cost per square metre useful?
It can help explain size, but it does not normalise material, design, hardware, service or useful life.
How should racers calculate value?
Use competitive hours or seasons at the required performance level, then include recuts, class or rating constraints and campaign downtime.
