What the indicator codes mean

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.
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.
BSpd	Base speed Distance a boat could average over 24 hours, empirically derived (Richard Boehmer, 1989). Also used to handicap mixed-fleet races.
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.
Texel	Texel rating (Multihull Dynamics) Multihull Dynamics simplified Texel approximation - matches the numbers they published. LOWER = faster.
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.
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.
KSI	Kelsall stability indicator Indicator of resistance to sideways capsize (Derek Kelsall). Higher = more resistant.

Performance indicators: SA/D, BN, BSpd (Boehmer), KSP (Kelsall), Texel. Stability indicators: SSpd, KSI. Calculated with the same equations published by the original Multihull Dynamics database. Texel* is the official CTC / Watersportverbond Texel rating (the global formula also used by OMR and Multi 2000) — it includes crew weight, so it reads on a higher scale than the MD Texel but ranks boats the same. Comparative aids only, not a stability assessment.
