Right of way:

A sailing vessel has the right of way over all steam or power vessels, except when she is the overtaking craft; then she must keep out of the way of the vessel overtaken. A “steam vessel” in the eyes of the law is any vessel driven by machinery, no matter of what kind or sort, and includes all gasolene, kerosene and electric boats. An auxiliary, if using her engine, is a steam vessel, and must keep clear of sailing craft, no matter whether she has sail set or not. Sailing craft must keep clear of rowboats.
