of the Industrial Invention entitled:

"FISHING BOATS WITH DOUBLE HULL STRUCTURE"

TEXT OF THE DESCRIPTION

The invention concerns the nautical sector relating to fishing boats.

More in detail, it concerns the construction of fishing boats characterized by a double hull conformation, such as to increase the stability of the vessel during navigation, and by the presence of floats, integral with the external structure of said hulls, capable of increasing its capacity to overall buoyancy.

It is known that, in the presence of rough seas, only the larger tonnage boats have the necessary stability to allow the completion of fishing operations without endangering the safety of the crews.

It is also known that these boats have management costs that make it impossible for them to be used in medium-small businesses.

The object of the present invention consists in overcoming the aforementioned negativities.

The purpose is achieved by means of a medium-sized fishing boat, characterized by the fact that it includes:

- a pair of independent hulls, mutually parallel, able to increase the stability of the vessel during navigation, even in the presence of moderately rough sea; - mechanical joining elements, such as to allow the connection of the aforementioned hulls;

- floats, integral with the external structure of said hulls, designed to increase their overall buoyancy capacity.

Such boats have the following advantages:

- greater stability during navigation, even in the presence of moderately rough sea;

- greater buoyancy capacity;

- possibility of being equipped with standard outboard motors;

- possibility of being equipped with motorized winches for the launch and recovery of fishing nets;

- low purchase and maintenance costs.

Further features and advantages of the invention will become more evident from the more detailed description set out below, with the help of the drawings which represent a preferred way of execution, illustrated by way of non-limiting example.

Figs. 1-2 show, in view and axonometric exploded view, the structural conformation of a fishing boat according to the invention.

Fig. 3 shows, in a complete axonometric view, the characteristics of a possible variant of the same, characterized by a greater load capacity.

Fig. 4 shows, in a complete axonometric view, the conformation of the safety seats with which the aforesaid variant is equipped.

With reference to the figures, the invention essentially includes:

- independent hulls 1, mutually parallel, able to increase the stability of the vessel during navigation, mutually connected by mechanical type junction elements 2;

- floats 3, integral with the external structure of the aforementioned hulls 1, designed to increase the overall buoyancy capacity of the same;

- rear projections 4, equipped with supports 5 such as to be able to accommodate the outboard motors responsible for propelling the vessel or the motorized winches designed to simplify the operations of launching and retrieving the fishing nets supplied to them;

- seats 6 designed to accommodate staff during fishing operations or in any case during navigation.

In accordance with the invention, the aforementioned fishing boats consist of a pair of independent hulls 1, mutually parallel, connected by mechanical type junction elements 2, on the external structure of which special floats 3 are constructively applied.

The double hull structure gives the boat greater stability during navigation, consequently reducing the risk of overturning, even in the presence of moderately rough sea, while the presence of floats 3 increases its overall buoyancy capacity, counterbalancing the weight upper part of the vessel, caused by the use of the pair of hulls 1.

These floats 3 have rear projections 4 capable of allowing, by means of the supports 5 connected thereto, to apply to the boats outboard motors or motorized winches designed to simplify the operations of launching and retrieving the fishing nets supplied to them.

The boats are equipped with seats 6, if necessary supplied with safety belts 7, suitable for accommodating staff during fishing operations or in any case during navigation and are equipped with refrigerated containers. 8, suitable for optimal fish conservation. during transport, placed inside the special housings 9 on the front ends of the hulls 1.

The aforementioned boats also have the characteristic of being able to be divided into pairs of small fishing boats, suitable for easy maneuvering along the coast and / or in confined spaces, through the separation of the hulls 1, determined by the release of the junction elements 2 related to them.

Naturally, without prejudice to the principle of the invention, the construction details can be widely varied without departing from the scope of the present invention.
