Sorry, Grace, but I have to quote the regs:
Sailboats under sail generally have right of way over most recreational powerboats, because sailboats are assumed to have more restricted maneuverability than powerboats (for example, a sailboat cannot turn and sail straight into the wind to avoid a collision). But by the same principle, sailboats must give way to any boat with less maneuverability.
Following is the order of increasing maneuverability. Any boat lower on the list must give way to boats higher on the list:
A disabled boat
A boat that is difficult to maneuver, like a dredge or barge in tow
A boat whose maneuverability is restricted by size or draft, like a freighter
A boat engaged in commercial fishing, like a trawler
A boat being rowed
A sailboat
A recreational powerboat
