In this work we present an optimization heuristic to approximate optimal minimum time sailing routes under non-uniform steady wind velocity fields. In the application of this heuristic, based in the simulated annealing method, the paths from point A to point B were modeled by concatenating a predefined few number
of oriented segments defined by previously established yaw points. The spatial non-uniformity of the wind field suggests the need to describe the trajectories from point A to point B using a cloud of numerous yaw points. The proposed methodology here called VSA (Vectorized Simulated Annealing) can address additionally the problem of existence of land masses or regions over which the crossing cannot be practiced. Preliminary numerical simulations indicate that the VSA methodology is effective in addressing the problem of finding optimal routes under non-uniform steady wind velocity fields. Besides, in the presence of a land masses blocking the way, the algorithm can generate credible alternative routes.
