The Sarca Excel is a certified Super High Holding Power anchor, it has a cast filled ballast to ensure self righting, it is a new design of 70 percent convex, 30 percent concave, part of this concave being the cutting edges.
Excel is not a plough anchor there are no plough sheers, in their place is what are called single plain concave flukes, this being the greater part of its concave arrangement, rather than plough the substrate this new fluke arrangement is designed to compress, then directs the material-substrate over the rear of the Excel forcing itself deeper as more load is applied.

As a world first, the steel Excel version has a stainless steel cutting toe in combination with a steel fluke, this toe is not unlike the original Super Sarca toe in its shape, turned down giving instant penetration, it can be sharpened for weed or hard substrate types, being of stainless the cutting edges do not rust, all of the above makes the Excel possibly the deepest diving anchor on the market allowing incredible performance in heavy weed and many sea bed types, check the independent holding power results of Robertson's anchor testing Authorities.
The Excel with its combination of convex –concave design has apertures along the sides of its flukes, whilst the anchor is being set these apertures allow water to be dragged through, this further aides the movement of compressed sea bed and assists the deep setting in hard mud or clay, these apertures work in reverse on retrieval and helps to bring up a relatively clean Excel on retrieval.
With its shank being of bisaloy 80 or equivalent the build strength from the number four anchor and up of the Excel is exceptional, the bulbous on the underside of the toe aids in the Excel turning through wind and tide changes.
The Excel anchors are available in the following; Steel hot dipped Galvanize, also in 316 stainless with a 2205 stainless shank.
Third concept of the Sarca Excel is an alloy version, this model has a removable shank that slides up from underneath, then attached with bolts that are not load bearing, great light weight design, easily stored, doubles as a primary, a great stern anchor with equivalent holding power of its heavier cousins in sand and mud, tip is weighted, shank strength is off high grade alloy 7075 – very near matching the strength of Bisaloy.
