Query: A Hybrid control approach to the route planning problem for sailing
  boats   We present an optimal hybrid control approach to the problem of stochastic
route planning for sailing boats, especially in short course fleet races, in
which minimum average time is an effective performance index. We show that the
hybrid setting is a natural way of taking into account tacking/gybing maneuvers
and other discrete control actions, and provide examples of increasing
complexity to model the problem. Moreover, we carry out a numerical validation
of the approach and show that results are in good agreement with theoretical
and practical knowledge.
