Lewmar Delta® Anchors The Delta® anchor is constructed of high-grade manganese steel and stainless steel for maximum tensile strength. Its unique shank profile and ballasted tip make it self-launching. And its low center of gravity and self-righting geometry ensure that it will set immediately. Consistent and reliable in performance, the Delta® anchor is guaranteed for life against breakage, has Lloyd's Approval as a High Holding Power anchor and is specified as the primary anchor used by numerous National Lifeboat Organizations.
