Westerly Fulmar

Fin, twin-keel and lifting-keel options with different drafts. The lifting-keel draft changes with keel position and should not be treated as one fixed figure.

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.

Ballast / displacement Ballast / displacement	—	Insufficient compatible data
SA/D SA/D	—	Insufficient compatible data
D/L D/L	251.46	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.
Comfort Ratio Comfort Ratio	22.68	Calculation & limits displacement_lb / [0.65 × (0.7 × LWL_ft + 0.3 × LOA_ft) × beam_ft^1.333] conventional-monohull-v1 Compare boats of similar size and type. Underwater hull shape, mass distribution and actual wave response are not represented. Input sources are shown with the corresponding specifications.
Capsize Screening Formula Capsize Screening Formula	2.03	Calculation & limits beam_ft / (displacement_lb / 64)^(1/3) 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	6.83 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.
Power per tonne Power per tonne	—	Insufficient compatible data

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

Propulsion

Engine power Engine power	—	Data awaiting verification

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.
