Lewmar Galvanized Claw Anchors: Weight, Chain & Size Guide

Lewmar's Claw is a one-piece galvanized-steel anchor with a curved shank and broad, claw-shaped flukes. The range includes several weights that look similar in photographs but differ substantially in overall size and Lewmar's recommended chain diameter. This guide identifies five exact galvanized Claw models available from NewRVParts and explains what to confirm before assembling an anchoring system.

Lewmar galvanized Claw anchor comparison

Lewmar assigns these specific model numbers to its 1-, 2-, 5-, 7.5- and 10-kilogram galvanized Claw anchors. The imperial weights in this chart are the manufacturer's stated equivalents. The recommended chain sizes come from Lewmar's anchor specification table; they are not a substitute for choosing the entire rode for your boat.

Part number Nominal weight Recommended chain Overall length B Height A
0057901 2.2 lb 5 mm (3/16 in) 11⅝ in 5¼ in
0057902 4.4 lb 5 mm (3/16 in) 14 3/16 in 7 3/16 in
0057905 11 lb 5 mm (3/16 in) 18 7/16 in 8 15/16 in
0057907 16.5 lb 6 mm (1/4 in) 19⅝ in 10⅜ in
0057910 22 lb 8 mm (5/16 in) 21¼ in 11⅛ in
Dimension labels: Lewmar's technical drawing identifies B as the overall length measured along the anchor and A as its height. The dimensions are nominal and subject to manufacturing tolerances. Measure the anchor compartment, bow roller and stowage path separately; a close match in length does not guarantee that a roller or anchor locker will accommodate the flukes.

Claw design and how it stows

One-piece galvanized constructionThe anchor is cast from steel with corrosion-resistant galvanizing for marine use. The Claw shape is intended to set and reset on different seabeds. Anchoring performance still depends on the ground, the vessel, rode design and setting technique.
Bow roller and locker clearanceLewmar describes the Claw as suitable for stowage on many bow rollers, including some twin-anchor arrangements. Confirm shank width, fluke sweep, bow clearance and securing hardware. The fact that a roller accepts another Lewmar anchor family does not prove it will fit the Claw.

Why chain size changes across the range

Lewmar recommends 5 mm (3/16 inch) chain for the 2.2-, 4.4- and 11-pound models; 6 mm (1/4 inch) for the 16.5-pound model; and 8 mm (5/16 inch) for the 22-pound model. That recommendation is one part of the specification. The correct chain grade, breaking strength, rope section, shackle connection and scope must also be selected for the vessel and conditions.

The listed anchor weight is not a guaranteed boat-length rating. Lewmar's anchor-selection chart is guidance based on boat characteristics. Windage, displacement, expected bottom conditions, weather exposure and local anchoring requirements can change the appropriate selection. Do not choose an anchor solely by matching a “boat up to” label.

Five checks before choosing an anchor

  1. Confirm the exact number. 0057901, 0057902, 0057905, 0057907 and 0057910 refer to different galvanized Claw weights, not colour or packaging variations.
  2. Review the vessel and anchoring conditions. Consider displacement, windage, local seabeds, sheltered versus exposed use and the manufacturer's selection chart before finalizing the weight.
  3. Check rode components. Match chain diameter and grade, shackle size and the rope or chain length to the whole anchoring system. The product listings are individual anchors; do not assume a complete rode is included.
  4. Measure stowage. Compare the overall size and fluke clearance with your actual bow roller, locker and retrieval path. Ensure the anchor cannot strike the hull when deploying.
  5. Secure the anchor correctly. Use appropriately rated hardware and a positive stowage restraint. Follow your boat, windlass and anchoring-equipment manufacturers' instructions rather than relying on the winch or roller alone to retain a stowed anchor.

Compare bow-roller options separately

For roller size and movement differences, see our Lewmar fixed versus pivoting bow-roller guide. Those two rollers are specified for particular Delta/DTX anchor sizes, so that guide should not be treated as confirmation of fit for a Claw anchor. Check Lewmar's current information for your exact anchor and roller combination.
