I can't fully understand the OP's post, or follow ups. Are you typing on a cell phone, or is this the way that you always type?
I believe that the OP was a question about the inland navigation rules, as they pertain to power and sail boats. You can find the law here:
Navigation Rules Online
The specific area in question is this;
Rule 18 - Responsibilities Between Vessels
Except where Rules 9, 10, and 13 otherwise require:
(a) A power-driven vessel underway shall keep out of the way of:
(i) a vessel not under command;
(ii) a vessel restricted in her ability to maneuver;
(iii) a vessel engaged in fishing;
(iv) a sailing vessel.
(b) A sailing vessel underway shall keep out of the way of:
(i) a vessel not under command;
(ii) a vessel restricted in her ability to maneuver;
(iii) a vessel engaged in fishing.
(c) A vessel engaged in fishing when underway shall, so far as possible, keep out of the way of:
(i) a vessel not under command;
(ii) a vessel restricted in her ability to maneuver.
[(d) (i) Any vessel other than a vessel not under command or a vessel restricted in her ability to maneuver shall, if the circumstances of the case admit, avoid impeding the safe passage of a vessel constrained by her draft, exhibiting the signals in Rule 28.]
[(ii) A vessel constrained by her draft shall navigate with particular caution having full regard to her special condition.]
(e | d) A seaplane on the water shall, in general, keep well clear of all vessels and avoid impeding their navigation. In circumstances, however, where risk of collision exists, she shall comply with the Rules of this Part.
[(f) (i) A WIG craft shall, when taking off, landing and in flight near the surface, keep well clear of all other vessels and avoid impeding their navigation;]
[(ii) a WIG craft operating on the water surface shall comply with the Rules of this Part as a power-driven vessel.]
Unless these other boats were either not under command, restricted in their ability to maneuver, or COMMERCIAL fishing vessels with their gear out (not two dopes and a six pack), the sailboat is the stand on vessel. From what I could discern, it seems like these boats were "buzzing" you, which is illegal.
If it were me, I would be on the horn (5 blasts) when it appeared that they were going to come too close. I would also have my cell phone at the ready to take a picture. I would then take appropriate action to prevent a collision. After the incident, I would let the CG know on channel 16. I would also follow up by phone with this guy if in MD;
