Hi Carny
It could depend on which Surprise you are asking about. There appears to have been 14 ships named HMS Surprise, three of which were built in the 18th century. Shot garlands were no longer bolted to the bulwarks on new ships by order of the Navy Board in 1780 and they were removed from the bulwarks on the older ships as well by the end of the 18th century.-(Peter Goodwin, The Construction and Fitting of English Ships of War, page 217) If this is the French capture Unite which was renamed Surprise, it may be a different story. As with other things in ships in those days there were many exceptions.
What ship are the two photos top right?
Thanks
Allan
