Unless the sailboat is overtaking a power-driven vessel, the powerboat is the give-way vessel.
the power driven vessel needs to give-way for sailing ships.
when the power-driven vessel is towing another boat and has difficulty maneuvering
The power-driven vessel should change course and speed.
When a sailboat is crossing paths with a power-driven vessel which one is the Give-way vessel
When the motorized vessel is a commercial vessel or when the motorized vessel has another vessel or person in tow.
There are general rules for which vessel should give way but circumstances dictate which vessel does give way and which one stands on.For instance, there are many occasions when a sailing vessel not only should but must give way to a power driven vessel. A few examples are as follows.If the power driven vessel is:Engaged in fishingEngaged in diving operationsNot under commandHas restricted manouverability due to its draught.Has right of way.See the link below for Rules for Preventing Collisions at Sea for a more comprehensive collection.
A PWC is a Power Driven Vessel so she must give way.
When there is a danger of collision, the "stand-on" vessel is the one that must maintain its course while the other must take avoiding action. Sailboats usually are the stand-on vessel when meeting a power-driven vessel, even if that vessel is another sailboat (if its engine is powering the boat, and regardless of whether its sails are raised or not). There are exceptions: if the power-driven vessel is "working," such as a fishing boat dragging nets, or the power-driven vessel is confined to a narrow channel due to its draft, then the sailboat must stay out of the way, by altering course if necessary. If a collision is imminent and the other vessel shows no signs of altering course, then the sailboat should take whatever course is necessary to avoid it.
If you are operating a motorboat and your motorboat is being overtaken by a sailboat, you should maintain present course and speed. The vessel that is overtaking another vessel is the give-way vessel, regardless of whether it is a sailing vessel or a power-driven vessel. The vessel being overtaken is always the stand-on vessel.
A sailboat under sale usually has the right of way over a power driven vessel. The exception is when the powered fishing boat or large commercial vessel is in a restricted channel area. In this instance, the sailboat would need to yield.
When a sailboat overtakes a powerboat, the powerboat is the stand-on vessel. (Ref: SB-29)
