Definitions
- the anchor described is used to immobilize any type of boat or vessel in ports or anchorage areas.
- the "spearhead” anchor was designed to give priority to the three essential characteristics of an anchor:
- the pressure of the tip of the anchor (Kg / cm 2 ) must be greater than the resistance of the soil. So it is necessary. 1) reduce the contact surface: the tip should be as sharp as possible.
- the density of the surface layer of the bottoms is generally high, increasing with depth.
- pressure exerted by the point of the anchor will, in most cases, be greater than the resistance of the ground and the point of the anchor will bury immediately. The traction exerted by the ship, will contribute to the burial of the anchor.
- the anchor must be pointed, the point downwards, the point ensuring better penetration of the funds.
- the widest part of the point connected to the quasi-elliptical lateral part of the shovel constituting the working surface of the anchor, ensures the holding of the anchor in the layers of lower density.
- a .NACA type profile airplane wing
- a "corner” surface will see this coefficient vary from 0.70 to 1.00 depending on the value of the angle
- a flat surface reaches a value of 1.20
- a concave surface reaches a coefficient of 1, 70.
- the working surface of the "spearhead" anchor will therefore have a concave profile, ensuring the best holding power.
- the material of the anchor can be chosen:
- the ballast can be made of a piece of cast steel or cast lead.
- the total weight of the anchor will be staggered between different models ranging from 6 to 40 Kilos. , to meet the needs of yachting and coastal fishing; larger weight anchors which can be carried out for larger ships or thalasso-industrial installations, fish farms, drilling platforms, etc.
- the five component parts of the anchor will be cut by flame cutting, plasma cutting or any other appropriate means, the angles of the point and tailstock are made with the folder, the shape of the shovel can be obtained by successive folding at the folder o better, by stamping under high pressure press or forgeag to obtain a perfectly concave surface on sheets of medium thickness; On larger models, the angulation can be obtained by cutting and then welding the various elements at the desired angle.
- the rod of trapezoidal section may have the angles of the small base, rounded or bevelled to facilitate penetration.
- the steel anchors will be hot-dip galvanized, then the appropriate quantity of lead will be poured into the tailstock of the anchors.
- the lead ballast pa a part with the same characteristics obtained in foundry, this part being made solitary of the shovel and the heel of the rod, pa solder , so as to respect the "chevron" shape of the cutting of the point BB '.
- a variant of this anchor can be made with a removable orchard, to allow easier storage of the anchor in the bottom of the boat, this removable anchor can thus constitute a rescue anchor.
