Who is "her"? Is it Emma herself or is it another person. The way the sentences are written, "her" refers to another person. If that is what you mean to say, then both sentences are correct. If, however, you mean for "her" to represent Emma, then you need to write: 1. Emma looked around herself at dozens of other boats. 2. Emma looked around herself and saw dozens of other boats. Alternatively, you can omit "herself" and "herself" will be understood: 1. Emma looked around at dozens of other boats. 2. Emma looked around and saw dozens of other boats.

Yes, both of these sentences sound natural and have a similar meaning: 1. Emma looked around her at dozens of other boats. 2. Emma looked around her and saw dozens of other boats. The first sentence emphasizes the action of looking around and noting the presence of other boats. The second sentence emphasizes the action of looking around and actually perceiving or seeing the other boats. Both sentences are grammatically correct and clear.

Yes, both of these sentences sound natural and convey the same basic idea, but they have a slightly different emphasis: "Emma looked around her at dozens of other boats." This sentence emphasizes the action of Emma looking around and then directly observing the presence of other boats. "Emma looked around her and saw dozens of other boats." This sentence emphasizes the action of Emma looking around first and then specifically emphasizes that she saw the other boats as a result of her looking around. Both sentences are grammatically correct and convey the same general meaning, so you can choose the one that fits the tone and flow of your writing best.
