Langan Design Partners recently completed work on a major refit for Axia, a 125’ ketch originally designed by Sparkman & Stephens. The project took place at Astilleros de Mallorca S.A. in Palma de Mallorca, changing the yacht’s deep racing keel to a shallow-draft bulb configuration for efficient cruising with minimal performance impact. Through advanced CFD analysis and structural redesign, we reduced the draft by over 3 feet while maintaining stability, lift, and handling. The rudder was also re-engineered to complement the new keel geometry.
