As above, please post a link to your slicer setting and that will really help.

However, a few points:

It seems that your Benchy is fairly small and this may affect the quality of the model. (try printing bigger if possible)

Also, your layer height (resolution) seems quite high. I would suggest a layer height of 0.1mm. Or if you want a really detailed model perhaps try 0.05mm layer height.

I can also see your infill lines showing through. Although this is common and probably not something that is very bad, you can fix this by having a thicker wall (try 0.8mm) or asking your slicer to print the wall before the infill.

I hope some of these above points help. With a picture of your settings I might be able to be of more help.
