Reference model · first version

Built from published nominal hull dimensions. Some moulded profiles are simplified; this is not yet a millimetre-verified replica.

Dimensions, sources and what’s provisional

The model uses the printed nominal values in the GRP hull measurement form, September 1998 issue, alongside the 2020 class rules. It does not use the handwritten measurements of the individual boat in the scanned form. Current drawings and rules still need to be reconciled before claiming complete dimensional accuracy.

Source dimensions: hull length; beam stations; bottom rocker stations; mast-hole position; daggerboard-slot position and opening.
Provisional: surfaces between stations; conversion from edge-zone measurements to physical chines; gunwale cross-section; laminate thickness; mast-support and midship-frame profiles; corner radii and drainage details.
The model is generic and has no manufacturer branding. It is an educational reference, not a construction or measurement-certification drawing.
