Hope this helps!! I copied and pasted so all the wording remained as written. In short you were the stand-on vessel in this situation it was up to the sailboat (give-way vessel) to alter course and overtake .

Any vessel overtaking any other vessel must keep out the way of the vessel being overtaken. The former is the give-way vessel and the latter is the stand-on vessel. This rule applies even if the overtaking vessel is propelled by wind, oars, or rubber band paddlewheel.
A vessel is deemed to be overtaking when coming up with another vessel from a direction more than 22.5 degrees abaft (behind) her beam. This is the angle prescribed by the stern light. At night, the overtaking vessel will see only the white stern light of the vessel being overtaken. If you see either side light, it is a crossing situation.
