note that SailboatDemo is not a GLScene app. It uses Firemonkey 3D platform. On fmx 3d there is no dedicated UI interface for the 3d scene. 3D objects are part of form components ( 3d viewport childs). FMX 3d platform dev seems to be slow. A few projects use it, from what I see. One exception is GBE3D by Grégory Bersegeay, a set of components including dynamic grids like the wave surface. On the sail model on OPYC app, I used formulas similar to "thin airfoil theory" to calculate each sail segment...

In OPYC app, sails are modeled as a chain of interconnected line segments on a box2d scene. The wind on the segments generates forces, which along the forces on the keel, hull and rudder, power the boat in some direction. So the 3D sail is actually 2D polyline, repeated vertically with different chords. A popular way to simulate sailboat performance is to use polar charts (speed x twa). These are available for most sailboats. btw I'm in São Paulo

I uploaded version 2.0 of SailboatDemo. It was corrected and extended in many ways. I'm using this 3D scene in the game "OPYC" ( iOS, Android and Windows ) . SailboatDemo form is all rigged to be controlled by external code. check this video: https://www.youtube.com/watch?v=M9_Z5RxW3Pc
