| Standard and webbing elongation | For textile lashing assemblies covered by EN 12195-2, the webbing elongation at lashing capacity (LC) is limited to 7%. | Lower webbing stretch helps limit movement as a secured load is subjected to transport forces. The 7% figure is a maximum, not a promise that every strap stretches by that amount. | Check the product documentation and label for the applicable standard and the webbing’s stated elongation at LC. |
| Lashing Capacity (LC) | Choose an assembly with a clearly marked LC appropriate to the securing arrangement and the boat’s transport conditions. LC is commonly marked in daN. | LC describes the rated lashing strength of the assembly. It is not the same as the ratchet’s tightening force or a lifting capacity. | Use the vehicle, trailer, and cargo-securing requirements to determine the needed capacity; do not select by strap width alone. |
| Standard Hand Force (SHF) and Standard Tension Force (STF) | Look for the SHF and STF values on the label or technical documentation. SHF is the reference hand force; STF indicates the standard tension force produced by the ratchet under the stated test conditions. | These values help buyers compare pretensioning performance. STF is not interchangeable with LC. | Compare clearly documented values and follow the manufacturer’s operating instructions. Do not assume that applying more handle force is safe. |
| Webbing material | Polyester webbing is commonly used for lashing straps. Check the material specification and any stated environmental or care limitations. | Material affects stretch, handling, and service life. Boat transport can expose straps to moisture, sunlight, dirt, and salt residue. | Inspect webbing regularly and rinse off salt or grime when appropriate. Replace straps with cuts, burns, heavy abrasion, damaged stitching, or unreadable labels. |
| Strap width and length | Widths such as 25 mm, 35 mm, and 50 mm are commonly available, but capacity depends on the complete rated assembly. Select a length that reaches the proper anchor points without excessive loose webbing. | The strap must fit the boat, trailer, and attachment points while allowing the ratchet to operate correctly. | Measure the required routing path and check the marked LC of the finished assembly, including its end fittings. |
| Ratchet and end fittings | Check the ratchet body, handle, stitching, and fittings for secure construction, smooth operation, and compatibility with the trailer’s rated anchor points. | A strap is only as suitable as its complete assembly and connection points. Corrosion or deformation can compromise safe use. | Confirm that hooks or other fittings cannot slip off or damage the attachment point. Keep metal parts clean and inspect them for corrosion or distortion. |
| Boat contact and edge protection | Use suitable protective sleeves, pads, or edge protection where webbing contacts sharp edges or delicate boat surfaces. | Chafe and concentrated pressure can damage both the webbing and the boat’s finish or structure. | Route straps away from sharp corners, hoses, cables, and fragile components. Recheck contact points after tensioning. |
| Application and safe use | Use ratchet lashing straps for securing cargo during transport, not for lifting. Secure the boat at suitable points and follow applicable local transport rules. | Correct lashing arrangements depend on the load, anchor points, and transport forces; a strap rating alone does not establish a complete securing plan. | Follow the boat and trailer instructions, secure loose equipment, stow excess webbing, and recheck tension during the journey where safe to do so. |
