The logo is dominated by a capital 'S' written like stylistic sea waves. Bold and predictable strokes form the 'S', symbolizing the vibrant nature of SOS. The colour used is metallic blue. Apart from being reminiscent of the colour of the sea, it also exudes a cool yet classic feel to the entire logo.

Placed against a white background, the metallic colour allows the capital ‘S’ and the words "Singapore Organisation of Seamen" to stand out in an obvious but harmonious way. There is a gradual transition of colour tones from white to blue. This adds body and signifies the ever changing and flexible nature of SOS in serving its members.

The box containing the words "Singapore Organisation of Seamen" signifies the unity that is an integral part of SOS. It represents a bringing together of members with similar interests and giving them a common identity. As an organisation, the box symbolizes stability too.
