The primary logo is the vertical lock-up version, with the brand mark above the logotype. This must be used whenever possible.

logo with tagline naming of elements: Sail is called brandmark, Hydro is called logotype. Logo with sail on top is primary variant, sail left of Hydro is secondary.
Please do not attempt to create art for the Hydro logo, brand mark, or logotype for any application. Use the files provided with this manual.

The secondary, horizontal lock-up, should only to be used when the available space is limited.

Clear space

logos with recommended celar space, which equals half the width or height of the sail
The same amount of open space also applies to the brand mark in situations where it is used by itself. The principles also apply for all other logo versions.

There must always be sufficient space surrounding the Hydro logo to avoid competition with other elements and to maintain its visual impact. The recommended open space is relative to the logo size, and is 1x the height of the brandmark. Try to allow at least this amount of clear space - it will help give the logo clarity.

Sometimes, the recommended amount of clear space will not be possible to achieve. In these situations, strive for a minimum open space of .5x the height of the brandmark. However, please note that the legibility and visibility of the logo takes precedence over clear space. Use common sense to find the right balance.

Minimum size

When the brandmark is used by itself, the minimum width is 5 mm. This is not necessarily a recommended size, it is the absolute minimum.

When the brandmark is used by itself, the minimum width is 5 mm. This is not necessarily a recommended size, it is the absolute minimum.

To ensure clean and legible lettering and art detail, the width of the primary Hydro logo must never be less than 10 mm. The secondary logo width must never be less than 17 mm.


These are the official versions of the Hydro logo. No other arrangement or color is allowed. They are available in EPS format, compatible with Adobe Illustrator CS6 or newer for both print (CMYK and Pantone) and screen (RGB).

Although the blue version of the logo is most widely used, it is never wrong to use the aluminium-colored logo. You are free to choose the version that works best for your specific project. The dark blue provides a distinct presence on light backgrounds, while aluminium is more subtle. Aluminium is preferred in premium printed matter where it may be reproduced in metallic Pantone 877 or matte silver foil.

The white (negative) version of the logo is intended for dark backgrounds. If the logo cannot be reproduced in color, use the black, white, or aluminium (CMYK) version. Never convert the dark blue logo to grayscale.
