Patented and ratified anchor R.I.NA Italian classification (amusement and fishing) for mud, sand and rock.
The anchor an excellent hold on all sea Floors.
it is only anchor in the world able to free itself (by means of counter weight) from every obstacle (ropes, chains and rocks) as soon as the anchor takes on a vertical position with respect to the bow and the bottom.
- It doesn't need to be bow- stowed.
-Paltry weight when pulled by hand since it comes up vertically without water resistance.
-There is no need to change anything on the right of bow because it adapts itself to all shapes having a 105 angle between shank and flukes.
- In the case of a boat with hawsehole there is no obligation to put the winch in a single position but it can even be placed on the anchor vertical.
- It doens't knock under the bow.  Anchor weights - from 3,5 to 1000 Kg. galvanized and stainless steel AISI 304.

All anchor, presently on the market, independently of their anchorage power, have the considerable inconvenience of easily running aground.
To avoid this problem, Giuseppe Amato, a master of foreign-going vessel with a thirty year career as a yacht captain behind him, has thought of making a new type of anchor that, in addition to a high anchorage power, would be able to free itself from any type of grounding.
In order to find the best possible solution, Amato has considered various factors, such as the present shape of the hulls, which have become considerably lifted with respect to the floating line, thus leading to a remarkable increase in the sail effect, and the evolution of the bows which afford greater living space and speed to the hulls to the detriment of the functionality in the use of the anchor, both from the practical aspect of positioning it at rest and in the ability to free it whenever it runs aground in those ports where there are no sag of chains or fixed moorings.
Afterwards, some inconveniences, that absolutely had to be eliminated, were considered.
When present anchors run aground, they really put the winches to the test, especially the electrical ones, where the automatic feeding system might come off.
The opening angles, 35 or 40, of the traditional anchors, force the arrangement of the winches in a fixed position, in and the anchor is weighed by hand, when it runs aground on the bottom one is forced to abandon it at sea in 90% of the cases.
Lastly, in case of very straight bows, when the anchor is pulled over the surface of the water it tends to hit underneath the bow itself; that is why one can see those ugly fronts or mobile guides whose functions is to take the anchor out and into the bow, while many seamen have tried to solve this problem with turnbuckles, or cables, on the anchor, in order to be able to turn it and hook it with the boathook.
On the basis of these presuppositions and at the end of a long series of studies and experiments, the Amato anchor, was made as the only one capable of eliminating all the said inconveniences.
But, let us now see in practice how this anchor was born.
Captain Amato had at his disposal, on board of his 5 meter launch, an umbrella-type anchor which always had the ability to run aground. In order to avoid this he thought of putting the chain hank at the centre of the stock and a small rope thread on the shank. This, way, when the anchor would run aground, it was sufficient to pull it with force; the thread would break and the anchor would come ip upside down, thus getting free of the obstacles. Out of this experience, a mobile arms anchor has developed (which has greater advantages over the fixed anchor) that would take care of any problem connected with its use.
The Amato anchor has a functional action radius which goes from the mobile to the fixed arms with an opening angle of 105 for each side. Actually it contains within itself two anchors: the plough anchor and the umbrella-type anchor, improved in their characteristics. In fact, when it is resting on a flat bottom it takes on a 20 angle because of the mobile flukes and a 5 angle a wedge entrance angle of 20 + 5.
While, should it position itself at 105 angle, if the chain is a peak, then there would be an umbrella-type anchor with arms for entire 360.
The anchor was with an immaterial equilibrium ability, in that the weight is applied to the centre of the apparatus and is equipped with counterweights (flaps), that have three specific functions:
- enable the mobile flukes to turn very quickly to unload the weights which have deposited on it after it has anchored;
- give the anchor a 20 angle;
- let the anchor place itself in a fixed point, without giving it that drifting movement due to the movement of the boat on the surface.
The Amato anchor allows an excellent anchorage on all sea bottoms, reaching its utmost on sand, thanks to its "suction effect" which is further improved by the drifting movement of the boat.
As soon as it lifts from the bottom, and it is able to turn, it acquires all those requisites which make it unique in its kind.
If it hooks on some chains, on the side of the flukes, since it has a 105 opening, the weight of the chains itself tends to let the grounding slip away. Then, once it has freed itself from the side resting on the weights resting on the back of the anchor. Therefore, it will not be necessary to free it when it is on the surface of the water; as soon as it becomes detached from the bottom, it takes on a vertical position with respect to the flukes and the shank which make it lighter than the others since it does not present resistance to water and, therefore, it can be easily weighed even by hand.
Another important characteristic is the fact that it always comes up in the same position, therefore it doesn't require stowing in the hawse. Then, as soon as the upper part of the shank touches the hawse, it tends to open towards the outside of the bulwark and it doesn't hit underneath the bow.
It hook on the reefs or in a sag of chains, as soon as the bow reaches the vertical line the anchor, by way of small bow movements, it easily frees itself from the grounding.
Another advantage that it offers is that the winch need not be positioned at a given point, but rather on a 360 circumference; furthermore, it can be adapted to any shape of forward quarter or bow-post, without needing additional intervention to change the structural shapes of the boats.
Therefore, there is the possibility of applying lower power winches and without having the automatic system come off due to overloading.
