215 SECTION 13 - Marine <strong>Products</strong>MARINE PRODUCTSAnchor SelectionOptimum design of an anchor is influenced by the specificcomposition of the ocean floor. Basically, we categorize theocean bottoms into three groups:1. Mud, or silt, which varies the most in consistencyand offers little resistance to forces.2. Sand, ideally the most consistent, and where anchorsspecifically designed, reach excellent holding efficiency.3. Rock, or Marl, poor holding ground where ananchor’s dead weight is its only asset.The efficiency of an anchor in a given test is expressed interms of “Holding Power” per pound of its own weight, notin “Proof test” which indicates physical properties of thematerial.The fluke angle of an anchor has a definite effect upon the“Holding Power.” The flukes should enter the bottom at anangle that will allow the crown, or head, to penetrate to adepth which can produce maximum efficiency: Additionally,we have determined the following:1. The angle of fluke penetration in mud bottomsshould approximate 50 o .2. In sand the penetration angle should be in the area of30 o .3. For anchoring in various bottoms a compromiseapproximating 43 o is desirable.Other considerations in selecing an anchor should include:1. Convenience for handling and stowing.2. Aptitude for taking hold.3. Physical strength.4. Freedom from fouling, which all anchors do, butsome in lesser degrees.5. Influence developed by the chain’s catenary, whichabsorbs shock loads, and lowers the angle of pull atthe anchor by its weight.The anchor is the key to effective anchoring or mooring. Itis essential to know what to expect from various anchors.The resistance of an anchor to being dragged through a soilhas been considered as occurring in two stages: first, bitinginto the bottom due to the ploughing effect of the flukes, andsecondly, maintaining a continuous resistance to drag after itis planted into the bottom.Holding power is directly proportional to projected flukearea, and shear strength of the bottom materials, andinversely proportional to penetration-area resistance. Inmany cases a smaller anchor with favorable fluke area toweight ratio is more dependable than a heavier anchor.Holding Power for the two most widely used anchors areas follows:1. Stockless Type anchors in sand develop a holdingpower to weight ratio of seven to one. In mud itdevelops three to one. The angle of penetration inboth cases is 45 o .2. Lightweight type anchors in sand develop a holdingpower to weight ratio of twenty to one, with the angleof penetration being 30 o . In mud it develops nine toone with the angle of penetration being 50 o .The depth of penetration in all preceding cases is compiledfrom three to seven feet in sand, and from seventeen totwenty feet in mud. All calculations incorporate a 0 o scopeangle.FOR MORE INFORMATION CONTACT OUR NEAREST BRANCH OFFICE
