Performance & stability indicators
Calculated from the specifications below. Comparative aids only — not a stability assessment.
| SA/D — Sail area / displacement Power-to-weight ratio of the rig — the classic comparison ratio. Imperial: SA ft² ÷ (displacement lb ÷ 64)^⅔. Higher = more powerful for its weight. | 27.88 (12.95 m² per tonne) |
| BN — Bruce number Power-to-weight indicator of speed potential (√SA ft² ÷ displacement lb^⅓). Below ~1.3 is slow in light airs; ~1.6 reefs early offshore. | 1.32 (27.42 metric scale) |
| BSpd — Base speed Distance a boat could average over 24 hours, empirically derived (Richard Boehmer, 1989). Also used to handicap mixed-fleet races. | 11.67 kn (21.6 km/h) |
| KSP — Kelsall speed prediction Derek Kelsall's performance index (PI-C × 10), expressed in knots — an estimate of speed potential on a reach. A value of 8 ≈ 8 knots in a 10-knot wind. | 8.52 kn (15.8 km/h) |
| Texel — Texel rating (Multihull Dynamics) Multihull Dynamics simplified Texel approximation - matches the numbers they published. LOWER = faster. | — needs LWL + sail area + displacement |
| Texel* — Texel rating (official / global) The authoritative CTC / Watersportverbond Texel formula - the same core used by OMR (Australia) and Multi 2000 (France). Includes crew weight, so it sits on a higher numerical scale than the MD approximation (identical ordering). LOWER = faster. | 137.7 (lower = faster) |
| SSpd — Stability speed Wind speed (knots) at which the windward hull of a catamaran (or main hull of a trimaran) begins to lift — Shuttleworth, incl. a 40% gust factor. Higher = more stable. | 19.24 kn (35.6 km/h) |
| KSI — Kelsall stability indicator Indicator of resistance to sideways capsize (Derek Kelsall). Higher = more resistant. | 32.36 (35.6 km/h wind equiv.) |

Official Texel* — propeller adjustment
Texel* above uses a propeller factor of 1 (retractable / unknown). Propellers are commonly swapped between otherwise identical boats, so pick a configuration here to compare like-for-like. Board type recorded: Fixed keel (no board) (already reflected in Texel*).
Texel* with propellers: —
