The next stage is to detail the deck and hull completely before the masts and rigging can be "tackled". Items such as anchors, ladders, railings, guns, hatches, pumps and winches are piece by piece created, assembled, painted or stained and applied to the model. Often the below-deck details have to be applied before the planking of the hull or decks is completed, as seen here with the double capstan of a USS President model.
In the Admiral Class examples here, all parts are custom created (scratch built).
Even though each ship model is completed with all it's components in place, the level of detail on those components is determined by the class: Commander, Captain or Admiral.
