Running on the assumption that you're modeling the Capt Henry Jackman after the William J De Lancey, a few suggestions:
A mottled red would be better than a flat red. It would look more like rust, and give some definition to the areas that are not really distinguished on the boat. Try using some sort of brush texture in whatever texturing program you are using, and use a different layer so that you can edit that particular part of the texture and move it around if you need to.
Looking at
this image, you can see two yellowish lines running the length of the boat. Adding those would probably bring in some detail.
In that image, there are also some things on the deck (grayish and a few white thingies) which could be added to give more detail.
