Description

The utility model relates to the field of shipbuilding, in particular to the creation of multi-hull vessels with a small waterline area, and more specifically to vessels containing surface and two underwater hulls.

Various vessels of a similar design are known.

Among the catamarans, there are variants with two semi-submerged hulls, each of which is formed by a fully immersed streamlined hull (gondola), connected by means of vertical struts, intersecting the surface of the water with a surface platform above which the superstructure block is located. The designs of pleasure boats or yachts, including catamarans, which, in addition to developed superstructures, have open decks for sunbathing (sunbathing) are widely known.

The closest set of essential features to the claimed utility model and adopted as a prototype is a multihull (patent for invention RU 2013278 IPC B63B 1/12, 1994). The invention relates to shipbuilding and for the creation of multi-hull vessels with a small area of the waterline. A multi-hull vessel comprises a surface hull, two underwater hulls and racks connecting the underwater hull to the surface hull. In order to reduce water resistance and reduce energy consumption during a ballast transition, underwater hulls with racks are made of several components. The central parts of the underwater hulls are made with the possibility of moving to the surface hull, and the bow and stern parts with the possibility of pairing with each other during a ballast transition.

Analysis of the technical characteristics of the prototype showed that, along with the advantages, there are significant disadvantages:

The complex design of the device for lifting the central parts of the underwater hulls to the surface hull and their descent to the initial position. In addition, the device partially clutters the sides and deck.

The utility model is based on the technical task of creating a multihull vessel, the design of which provides relaxation in the coastal zone of sea and inland waterways. Recreation includes sunbathing (sunbathing), swimming from the side of the ship, holding discos afloat, etc. In this case, the movement of the vessel should be economical, and stay on it safe.

The stated technical problem is achieved by the fact that the claimed utility model is a self-propelled small-sized vessel, the constructive type of which is a catamaran with a small area of the waterline (trisek). The claimed vessel contains two underwater hulls in the form of cylinders having a pointed fore and aft ends. Two racks on each cylinder connect underwater hulls to the surface hull in the form of a three-dimensional platform forming a spacious open deck.

Racks with underwater housings are a single, one-piece fiberglass structure filled with polyurethane foam. Connect the racks to the deck using fasteners in the form of bolts.

The thickness of the cylinder linings is 6 mm. The dialing system is longitudinal. Flora 4 mm thick. Longitudinal beams of the set - U-shaped profile 4 mm thick, filled with polyurethane foam.

At the bottom of each cylinder, approximately 150 kg of solid ballast is stacked and securely fastened. Filling cylinders - polyurethane foam.

The deck of the vessel is a two-layer (plate-set-plate) fiberglass platform with a base thickness of at least 100 mm. The lower and upper layers of fiberglass deck - 3 mm, the thickening of the lower layer in the area of the racks - 6 mm. The side part is 4 mm. The deck set system is mixed. The longitudinal and transverse beams are 2 mm thick. The deck is provided with local wooden linings / reinforcements, holes for fastening and laying ship devices and systems. The thickness and the number of bulkheads and sheathing may vary depending on the size of the vessel or changes in design loads.

In the aft end of the deck installed transom device for mounting the outboard. The transom device comprises a transom board rigidly connected to a metal frame pivotally mounted below the deck. The transom installation height is adjusted by hand winch. The transom design provides the necessary outboard immersion over the entire rainfall range. Contains ladders for lifting swimmers from the water to the deck.

The essence of the utility model is illustrated by drawings of the General arrangement, which shows:

In FIG. 1 - declared vessel, side view;

In FIG. 2 - the declared vessel, top view;

In FIG. 3 - the declared vessel, view of the bow.

As shown in FIG. 1, 2, 3, the claimed vessel contains underwater hulls 1, a deck 2 formed by a platform, racks 3 connecting underwater hulls to the deck, a transom device 4 for mounting an outboard, a metal frame 5 hinged under the deck, a manual winch 6 allowing the engine to be immersed to the required depth , the installation site of inflatable elastic tanks 7, the installation site on the deck of the springboard 8 for diving, a ladder 9 for lifting swimmers from the water to the deck.

The claimed utility model works this way.

All structural elements (deck, racks, underwater hulls) are airtight, without buoyancy volume hatches, providing a buoyancy margin and a high degree of division into compartments. Due to the volumetric deck, a margin of stability is ensured at large roll angles. To maximize such seaworthiness as stability and buoyancy, the ship along the sides under the deck can be equipped with inflatable elastic tanks attached to the racks.

A high degree of unsinkability is ensured by the following design features:

- cylindrical underwater hulls and racks filled with polyurethane foam;

- the volumetric hollow deck is divided into impermeable compartments (cells), which resulted in the fact that the emergency stability parameters when receiving a break in the outer skin do not differ from the stability parameters of the vessel in an intact state;

- the shape of the hull of the catamaran with a small area of the waterline allows to achieve a significant reduction in resistance to movement of the vessel.

The design of the vessel allows you to additionally place on it:

anchor, mooring, towing device and supply to them;

guard rails (railing) around the perimeter of the deck to protect the crew and people resting on the deck;

ladders for people to get out of the water;

diving board;

a bathroom cabin with a dry closet, a washstand and a waste basket;

tent device or umbrellas for protection from the sun and rain;

lockers for storing ship supplies and personal items;

spotlight;

sun loungers for relaxing and sunbathing;

- refrigeration unit for drinks and food.

The design of the vessel allows it to be provided with life-saving, fire-fighting, navigation equipment, communications, signal lights and figures in accordance with the standards of the technical supervision body or in excess of established standards.

As a result of the implementation of the claimed utility model, we obtain a ship that provides a safe and comfortable stay in the beach area offshore, while such a rest is economically low-cost and safe for vacationers.

The design of the vessel allows it to be equipped depending on the specific task set by the customer for the construction of a multi-hull vessel.
