<p>Pitch and heave are limiting motions when driving at high speed on water. The installation ofa T-foil is an effective solution that reduces these motions. Commercial T-foils are available,but today none of them are non-magnetic. This thesis studies the possibility to design anon-magnetic T-foil that can carry the considerable loads that such a constructionexperiences. The T-foil is designed for vessels such as the Visby Class corvette.</p><p>Vortex lattice theory is used to calculate the pressure distribution acting on the construction atdifferent load cases. Required laminate thickness is determined by iteration using a linearfinite element model of the fin.</p><p>The conclusion is that it is possible to manufacture a non-magnetic T-foil of the required size.A critical area in the construction is the T-joint between the vertical strut and the horizontalfoil. Future investigations should include laboratory tests of the T-joint as well as moredetailed hydrodynamic analysis for more accurate input parameters of the T-foil.</p>
