OverviewComfortable Anchoring Without Rolling! Reduce boat movements by up to 50% with our innovative boat stabilizer. The stabilizer is especially recommended for seasickness and longer trips and ensures a peaceful anchoring experience.
Key benefits- Reduce rolling: Effectively reduces boat movements by up to 50% (actual effectiveness depends on vessel type, size, weight, number of stabilizers used, wave conditions and placement).
- Easy installation: Secures with a single external rope slightly deeper than the hull (depending on sea conditions). Can be positioned at the side, bow or stern.
- Compact storage: Foldable elements allow easy storage in a durable, water-repellent bag when not in use.
- Multiple stabilizers: Depending on your boat’s weight, one or several stabilizers may be used. When using multiple units it is recommended to mount them on the same side for stronger braking resistance.
How it worksThe SWI-TEC stabilizer has the shape of a box with movable plates that is lowered into the water. These plates act like a valve: during downward motion the plates open to let water pass through; during upward motion they close and dampen the movements. The surface area and design of the anti-roll system reduce side-to-side movement.
Usage recommendations- Only used when stationary at anchor or in port — never while underway.
- Placement can be at bow, stern or side depending on wave direction and desired effect.
- Refer to the manufacturer's weight/units table to determine how many stabilizers your boat requires; suitable for boats up to approx. 25 tons depending on number of units.
Limitations & safety- Not recommended in very rough seas or extremely high waves (risk of overloading cleats or railing supports).
- Less effective if placed too close to the hull.
- May contact underwater obstacles (seagrass, wreckage, tidal currents).
- When deployed at the bow it may interfere with the anchor chain.
Maintenance & storage- Rinse with fresh water after use to avoid salt deposits.
- Check for damage or corrosion regularly, especially on connecting elements, loops and screws.
- Only pack into the storage bag when completely dry to prevent moisture damage.
