Unimer Marine – Smarter Mooring Compensators for Sailing Yachts

Reliable mooring protection born from Scandinavian design

When you’re moored in a gusty marina or a tidal harbour, every surge or wave puts your lines and fittings under strain. That sharp jerk on a cleat isn’t just uncomfortable — it gradually weakens ropes, deck fittings, and pontoons. Mooring compensators solve this by absorbing shock loads before they reach your boat, extending the life of your equipment and ensuring a quieter, more secure berth.

Proven Scandinavian Engineering

Swedish manufacturer Unimer Marine has been designing and producing high-quality rubber components for over 30 years. Their range of mooring compensators is trusted by sailors worldwide for its durability, performance, and simplicity. Whether you’re securing a 30-footer in a marina or a 50-footer on a swinging mooring, Unimer offers models tailored to match your yacht and conditions.

Why Use Mooring Compensators?

Even in calm weather, a moored yacht is rarely still. Wind gusts, passing wakes, or tidal movement can generate sudden tension in the lines. Over time, these shock loads fatigue ropes and deck hardware.

A mooring compensator acts as a shock absorber, adding controlled elasticity to the system. It reduces noise, protects cleats and fittings, and prevents excessive strain on lines — all while keeping your yacht stable and comfortable.

The Unimer Marine Mooring Compensator Range

All Unimer Marine mooring compensators share the same core design principles:

- High-quality natural rubber or thermoplastic construction for long-term elasticity.

- UV, ozone, and saltwater resistance for durability in harsh marine environments.

- Progressive load response, softening light tugs and damping heavier surges.

Each model, however, is optimised for slightly different needs:

Model	Key Feature	Best For
Standard	All-round performance and durability	Everyday mooring protection for most sailing yachts
Inline	Slim, compact design	Boats with limited storage or small mooring cleats
Classic	Lightweight and easy to handle	Smaller yachts and dayboats
U-Cleat	Quick-fit removable cleat	Yachts where mooring lines are frequently changed or adjusted
Smart Snubber	Clip-on thermoplastic design	Travelling sailors or secondary mooring damping

How to Choose the Right Mooring Compensator

Selecting the best mooring compensator depends on:

- Boat size and displacement – larger yachts need higher-capacity compensators and matching rope diameters.

- Mooring conditions – sheltered marinas require less damping than exposed harbours or tidal berths.

- Ease of use – some sailors prefer permanent fittings, others value quick, tool-free installation.

General guidelines:

- The Standard model suits most 30–50 ft sailing yachts and remains the most popular all-round option.

- The Inline and Classic mooring compensators are lighter, compact choices for smaller boats or tight storage.

- The U-Cleat mooring compensator offers the flexibility to swap or adjust lines quickly.

- The Smart Snubber compensator is a portable choice for cruising sailors needing extra damping at unfamiliar moorings.

Tip: Match your compensator to your mooring line diameter, not just boat length.
