Very nice, have just restarted 1/1200 coastal warfare stuff recently after not touching it for well over a year, and am inspired to do some experimenting with smaller-scale splashes for 1/1200 vs your 1/700.
There used to be a company called Clydeside that did very nice little 1/1200 splashes in pewter or resin but they went out of business abruptly (owner died unexpectedly!) sometime in 2020 just as I was getting into this naval stuff...
