White or cream could form the base colours for the spaces to be designed in the nautical theme.

Shades and tones of blue can obviously bring home the memory of the ocean and the sky.

Hints of red can be introduced to add a shade of warmth among all the cool colours being used.

Antique white, deep aqua, navy, wine and burgundy can also be used to introduce alternate colours into the nautical palette.

The natural shades of wood also help add some yellow warmth to the space and is advised to be used in pockets with clear finishes.

Nautical motifs can be used to create wallpaper patterns.

The anchor is a commonly-used motif to consider to tessellate if required.

Starfishes, shells, fishes or whale icons can be used as well.

Rope patterns or their knotting styles in repetitive motifs can become a pattern to used on walls or upholstered elements as well.

The ships steering wheel can be used as an antique wall decor element.

Other nautical equipments, like measuring instruments, telescopes, etc., can also be used for this purpose.

Ropes can be used on ceilings or walls to connect or hang items, they can also be used in knots as a replacement to drawer knobs.

Oars and run-down boats can be reused or up-cycled as well.

Up-cycling or reusing wood or other elements of older furniture to create the furniture for this concept is not just appropriate, it is also a fun activity to execute on your own and a cheaper alternative.

Opaque-coated finishes on the wooden furniture works best here.

Run down coats of opaque paints, then finished with a clear wood finish to protect the furniture from damage or decay, is a good approach to achieve this look and feel of a nautical interior space.

Elements like rope and rusted metal ship elements can also be used to create or decorate furniture elements.
