If you can get ahold of a copy of “Chapman's Piloting, Seamanship, and Small Boat Handling,” I'm using the 62nd Edition, starting on page 134 it discusses the "Rules of the Road" with the pertinent parts being on page 138, "Determining Safe Speed"; page 139, "Determining Risk of Collision" and "Actions to Avoid Collisions"; page 140, "General Right of Way Provisions," "Actions by the Give-way Vessel"; page 142, "Sailing Vessel Rules"; particularly the part on Page 143 titled "Sail's right of way over power."
I think that these sections should give you enough background material to make the case.
