Hi Alex,
I see nothing wrong with your pics, apart the last one which could have been slightly overexposed.
In situations as these, at the coast, you have to deal with a large amount of UV light, and a Yellow/K2 filter could had help. Also, there will be - possibly - a lost of definition in your photos with a narrow angle from the camera toward the sun, even you have done a good job with metering, correctly compensating the exposure given by your meter. Your photos could be easily adjusted with "curves" in PS after scanning.
I have made also a bunch of pics with FP4+ and dev. with Agfa Rodinal, that's a great combo, but the film I have prefered to work with the photos above would be first Fuji Across ISO 125 or T-Max 100, due to its increased tonal expansion capabilities with a immense contrast scene as shown. Pyro aficionados would even had prefered this, due to the great highlights detail retained with that developers. Remember you are not forced to have pure white and black in every single photo, that's just a matter of personal taste,
Cheers,
Renato
