1. A submersible vehicle for use in a body of liquid, the submersible vehicle being an underwater glider, and comprising:
- a vehicle body;
a pair of fins coupled to the vehicle body on opposed sides thereof;
a dihedral angle control system operative to vary a fin dihedral angle of each of the fins; and
a buoyancy control system operable to selectively generate vertical force on the submersible vehicle by varying a buoyancy of the submersible vehicle;
wherein the shape of at least one of the vehicle body and the pair of fins is configured to convert at least part of the vertical force into a forward glide thrust on the submersible vehicle.
