A sail does not die of depth. It dies of the draft creeping aft, and that starts years before anyone says the sail looks tired.
Ask most owners how many hours are on their mainsail and you get a shrug and an estimate. The estimate is almost always low. Ask them what their genoa cost per hour of use, or which sail to budget for next, and there is no answer at all — not because the question is hard, but because nobody wrote down the two numbers it needs.
This record holds the wardrobe: what each sail is, what it cost, where it actually lives, how many hours it has been set, and the two ratios that show it losing the shape it was cut with.
What you receive
A six-part record for the life of the wardrobe
- A 24-line reference page for the cloth, wind ranges and service intervals you transcribe from your own loft, with the source and page beside each
- A 20-line wardrobe inventory — cloth and weight, year, cost, sail number and, in the column almost nobody fills in, exactly where the bag is stowed
- Twelve sails across six seasons of cumulative hours on a single spread, with season notes underneath
- Draft depth and draft position measured as ratios, per sail and over time, with the method recorded once so the readings stay comparable
- A 20-line condition register and a separate 14-line loft assessment — deliberately not the same page
- An 18-line repair register and 6 calculation models for life consumed, usage rate, seasons remaining, depth, draft position and cost per hour
The two numbers that change how you buy sails
Model S2 is a usage rate: hours between two season closes, divided by the seasons. It sounds trivial and almost nobody has it. Model S3 takes that rate and the life your loft quoted and tells you how many seasons are left — which turns a new mainsail from a Friday-in-June emergency into a line in next winter's budget.
Model S5 is the sleeper: how far aft the point of maximum depth has moved, as a share of the chord. A stretched sail closes its leech and stops the boat pointing long before it looks worn out, and this is the measurement that catches it.
Not one published service life. Deliberately.
A cruising dacron mainsail and a racing membrane headsail of the same age have nothing in common. Service life depends on the cloth, the construction, the boat, the water it is sailed in and what you ask of it. Any single figure printed here would be wrong for most readers and expensively wrong for some. So you transcribe yours once, from your own loft — and if they gave you no figure, the blank line is itself a finding.
Judging a sail is a sailmaker's work. This is a record of it.
No page here tells you when a sail is finished, whether a recut is worth it, or whether a repair is economic. Those judgements are made with the sail flat on a loft floor by somebody who has seen a thousand of them. Part IV is split for exactly that reason: twenty lines for what you can see, feel and photograph, and a separate fourteen recording what a loft assessed, what they found and what they recommended — with their name against it.
The column crews thank you for
The inventory has a field for where each sail is stowed, in words a stranger could follow. “Forepeak, port side, third bag from the bulkhead” beats “forepeak” by an hour on the morning you need the storm jib, in the dark, with somebody else's crew aboard.
Who it is for
- Owners with a wardrobe accumulated over years and no idea what any of it has done
- Racing crews who need to know which sail is losing shape before the season, not during it
- Anyone weighing a recut against a replacement and wanting the arithmetic rather than the feeling
- Owners preparing to sell, where an undocumented wardrobe is valued as an old one
How it relates to the Standing Rigging Record
The Standing Rigging Record covers what holds the mast up. This one covers what drives the boat. They share a reference-page method and a season rhythm, and together they are the complete paper history of everything above deck — which is the half of a boat a surveyor can least easily reconstruct from an afternoon's inspection.

What it is not
This document records, structures and compares figures that you supply. It publishes no service life, no wind range, no draft depth, no replacement interval and no threshold at which a sail should be retired, and it reaches no conclusion about any sail.
It is not a sail assessment, not a trimming guide and not sailmaking advice. Those judgements belong to a qualified sailmaker working with the sail in front of them.
