Armstrong front wings and foilboards

Every Armstrong hydrofoil front wing: 52 wings across 11 families, with true area in cm² and span in mm, taken from Armstrong's own published specifications, except 12 read from a retailer, distributor or review. Aspect ratios include recorded calculations or values whose origin is not established; qualifications are explained below the table.

Every Armstrong front wing in the dataset. Area is true area in cm², converted where the brand publishes square inches or numbers its sizes by span. Aspect ratio retains the recorded value unless span² ÷ area differs by more than 10%; geometry is also used when no value is recorded. A calculation or unknown origin is marked, even when the numbers agree.

14 of 52 aspect ratios on this page are qualified. 7 marked derived from span/area: The brand publishes no aspect ratio; this one is derived from its published span and area (span² ÷ area). 6 marked published (geometry differs 5-10%): The brand publishes this aspect ratio, but its own span and area (span² ÷ area) give a figure 5–10% away. The published number is kept and marked. 1 marked recorded (origin unknown): This aspect ratio's origin is not established in the research record. Agreement with span and area does not establish that the brand published it. 52 of 52 areas on this page may be projected or flat: Armstrong does not state which it publishes, and the two run 3–8% apart. Those are marked like that, and hovering one gives the reason. Every other aspect ratio is Armstrong's own, and reconciles with Armstrong's own geometry.

How to read these numbers

The number a brand prints on a wing is not comparable across brands: some name a wing by its area in cm², some by its span in millimetres, some by square inches. Everything here is converted so the columns mean the same thing on every page. Where a brand's published aspect ratio contradicts its own span and area by more than 10%, the geometry is used instead and the row says so on the map.

Every Armstrong foilboard: 60 boards across 7 families, with volume in litres, length in feet/inches, width in inches and slenderness, taken from Armstrong's own published specifications.

How to read these numbers

Volume is printed in litres by nearly every brand, often in the model name. Board lengths are in feet and inches; widths and thicknesses in inches. Explicit source imperial figures are retained where they agree with the stored measurement. Otherwise lengths are converted to the nearest 0.1 inch and widths and thicknesses to 0.01 inch, using exactly 25.4 millimetres per inch. Volume stays in litres. Missing dimensions stay blank; calculations and drawings use the unrounded stored figures. Slenderness, length ÷ width, is computed from the brand's own two figures and never typed in: how long a board is for its width. Discontinued boards are shaded. Mount is the brand's own statement of how a mast attaches.
