Sail plan, sail condition and actual loading affect behaviour. A single number cannot predict performance.

Comfort and behaviour at sea

The indicators below help compare proportions. Interpret them alongside hull shape, mass distribution, loading, condition and sailing conditions.

SA/D SA/D	—	Insufficient compatible data
D/L D/L	187.73	Calculation & limits (displacement_lb / 2240) / (0.01 × LWL_ft)³ conventional-monohull-v1 A conventional indicator calculated from this configuration's published data. It is neither a safety certification nor a prediction of an individual boat's condition. Input sources are shown with the corresponding specifications.

Theoretical hull speed Theoretical hull speed	7.9 kn	Calculation & limits 1.34 × √LWL_ft conventional-monohull-v1 Conventional approximation for displacement hulls, not a rigid limit or a guaranteed cruising speed. Input sources are shown with the corresponding specifications.

It is neither a safety certification nor a prediction of an individual boat's condition. Input sources are shown with the corresponding specifications.

These calculations are not safety certificates. STIX and AVS require specific documentation; they are not estimated from these ratios.

The original engine may have been replaced. Power, propeller, transmission and conditions together determine real use; consumption and range are not inferred from power alone.
