Everything would have been in focus at f/1.4. I chose f/8 as my go-to aperture on that lens because it's sharp at that aperture. That aperture also allowed me to use the camera's base ISO at a shutter speed (1/160) that was fast enough to handhold the camera, so there was no reason to use any other aperture.
As for the exposure, it was a piece of cake. Using matrix metering and exposure compensation of -1/3, the histogram looked ideal. After post-processing everything, the clipped highlights and shadows are minimal and in unimportant areas of the image.
EDIT: The white boats and building that you mentioned aren't particularly bright; they are only in Zone 8. Most of the bright tones in the sky are in Zone 8 and a small portion has tones in Zone 9. There's nothing noticeable in the image that has tones in Zone 10 (by design).
Hope that helps!
