Under RIPA Rule 14, what action must two power-driven vessels take when meeting on reciprocal or nearly reciprocal courses (Head-on situation / Situación de vuelta encontrada) so as to involve risk of collision?

1. Both vessels must stop engines and drift until one passes
2. Both vessels must alter course to port (left) and pass starboard to starboard
3. Each vessel must alter her course to starboard (right) so that each shall pass on the port (babor) side of the other
4. The faster vessel maintains course while the slower vessel makes a complete 360-degree circle
