Tamiya's 1/700 DKM Gneisenau, in a small diorama with Skywave's Narvik class destroyer and S-boats.
Ships may be unrealistically close together (sound collision!) but I don't build many of these types of things as it is, because of the greater space they take up.
The Tamiya Gneisenau is a gem. One of the best of the original waterline series.
This is probably my most successful attempt yet at creating realistic water. It's painted acrylic gel coated with ModPodge
