This thesis focuses on re-designing the hydrofoil mast-board connection of a kitesurf hydrofoil

board manufactured with a 3D-printed lattice core and composite sandwich skins, aiming to

improve structural performance and production repeatability in a real industrial collaboration.

Within the available test range, the PVC two-rail configuration performed best and most

consistently. All three rail samples reached the maximum available load (132.2 kg),

corresponding to approximately 1.39 kNm, without visible structural failure (testing was stopped

because no additional weights were available). This indicates at least a ≥1.39 capacity relative

to the 1.2 kNm design target within the tested range.
