I made a few modifications to the kit based on the box art and photos of ORP Ślązak I found online: I eliminated the bow flagstaff, made the rear mast taller, and added life rafts to the sides of the superstructure.
Sea texture was built up with Modpodge and Mig Ultra glue over painted base. Both products dry clear, so allow the color to show through, and add a bit of depth. Foam and wave crests were then painted on, and a final coat of acrylic gloss varnish was applied.
