when the power-driven vessel is towing another boat and has difficulty maneuvering
The power-driven vessel should change course and speed.
Steer into the wind.
When the auxiliary engine is not running or is being assisted by sail power
Keep clear... The power driven vessel should, if possible, maintain course and speed. The only rule for overtaking is that you keep your distance while overtaking
No, there are a several rules about where and how a power driven vessel is deemed to be either the give way or stand on vessel. A link is provided below for both International and Inland Rules. Please refer to Rules !3, 16,17 & 18.
When the sails are furled and it is proceeding under its auxilliary engine
When sails are up and are producing more momentum then power (if the vessel is still using power to make way)
Fishing skiffs (flat-bottomed) are often fifteen feet long or less, and they are power-driven.
When the motorized vessel is a commercial vessel or when the motorized vessel has another vessel or person in tow.
