Increase the spacing to 200 or 300% or more and set the angle jitter to direction and then save this as a new brush and delete the previous one. Now, create a new layer and stroke the path again. This will work best if the path you make is a closed path, like a shape, and here's why - your slope line brush will make slope lines on either side of the path so you have to delete the lines on the "inside" so if you have a closed shape path you can turn the path into a selection (on the paths tab) then use the selection and the delete key instead of nit-picky erasing minute little bits at close zoom. So you will now have the outline and the slope lines all the way around so if you want an open end, take an eraser and erase.

Another option would be to create a bush that has the scallop dark ridge line and some slope lines and stroke a path with that but your path will have to be a bit wider than you initially draw since stroking the path runs right down the middle.

Or you could just use a 3-pixel round brush and draw a bunch of lines by hand...either way is tedious.
Thanks, I appreciate the suggestions. I also like the water line work from the era.
