Abstract
Description
- The present invention is concerned with a hull assembly for an aquatic vessel, particularly for a high speed catamaran or trimaran vessel.
- Conventional large volume vessels for transporting passengers typically have a metal hull made of aluminum or steel. Some of the disadvantages of the metal hull are its large deadweight and consequent low speeds attained by the vessel.
- US patent No. 5,873,130 discloses a catamaran style vessel with a hull having a generally T-shaped cross section with multiple compartments for liquid cargo occupying the majority of the hull volume. However, the compartments are made of metal and therefore still suffer from the weight disadvantage.
- The following documents are directed to different vessels provided with inflatable hulls:

Thecatamaran vessel 10 is designed to reach speeds from 20 knots up to 120 knots. This is achieved by the use of high performance construction materials and the dynamics used in the design. Thiscatamaran vessel 10 is also adapted to airborne on its entire length. Even though the example that is illustrated is that of a catamaran vessel, It should be understood that other types of ships such as mono hulls ships, or trimarans are encompassed by the teachings of the present invention. - The platform designs are based on the Venturi principles and wing effect on its superstructure for lifting and sustaining the
vessel 10 in an airborne travelling mode. Thevessel 10 has a flying wing design producing a substantial lifting effect at low speed. The wing design combined with the Venturi principles allow thevessel 10 to airborne within its own length. - The
catamaran vessel 10 has twohulls 12, one of which is shown in Figure 1. Above the hull is thecabin 105, which may have several closed decks.

catamaran vessel 10 according to the present invention is relatively very low at about 0.55 meters draft as compared to other vessels of same size, which vary from 1.5 to 3 meters draft. This is mainly due to the light weight materials that are used for thehulls 12. - Referring to Figure 2, there is shown a top cross sectional view of the two
hulls 12 of thecatamaran vessel 10. Eachhull 12 is made of a plurality of flexiblemodular containers units 16 that are connected together to form anouter shell structure 14 with an innerhollow section 18.

Themain section 22 is typically 42 meters long and has the narrowest portion of thehollow section 18. Thebevel section 24 is typically 6 meters long and has ahollow portion 23 that is tapered. Thepower room section 26 is typically 14 meters long and is provided with a largerhollow portion 27 for housing the engines of thecatamaran vessel 10. Thestern section 28 is typically 4 meters long. All hollow sections preferably communicate with each other. As shown, transversestructural beams 30 join bothhulls 12 together. - Even though only two
hulls 12 are illustrated, those persons skilled in the art will understand that a different number of hulls may be used according to the present invention, depending on the preferred design. - Referring to Figure 3, there is shown a cross section of the
catamaran vessel 10 in themain section 20. Eachhull 12 is made of a plurality of flexiblemodular container units 16. Also shown is theframe 107 of thecabin 105. Theframe 107 may be made with thesame container units 16 as thehull 12. Theframes 107 are preferably airframes that are equipped with air bags for structural purposes as will be explained below. Just as thecontainer units 16, all air framedsections 107 are prefabricated and assembled together directly on the high speed craft with an adhesive and covered entirely by an outer skin of a mix of carbon fibers, polyethylene fibers, such as Dyneema™, and aramid fibers, such as Kevlar™, bonded together with epoxy resin. - Referring to Figure 4, there is shown a cross section of the
catamaran vessel 10 in thepower room section 26. Eachhull 12 has the largerhollow portion 27 for housing theengine room 110. This section is relatively wider than the front section to allow more space for the engines and appropriate equipment. Theframe 107 of thecabin 105 is provided withapertures 99 such as ventilation ducts and wiring channels. - Referring to Figure 5, there is shown a section of the
hull 12 that is made of the flexiblemodular container units 16 according to a preferred embodiment of the present invention. Thesecontainer units 16 have different shapes from each other in order to form one section of the hull. Several of these sections, with varying shapes depending on what part of the hull is made, are assembled together to form theentire hull 12. Thecontainer units 16 are connected to each other preferably by means of a flexible adhesive material. - The
modular units 16 are bonded together as well as to the inner keel (shown in Figure 7), which provides the longitudinal strength for thecatamaran 10 and serve as the back bone of allmodular units 16. - Referring to Figure 6, there is shown a single
flexible container unit 16. Also shown is its correspondinginflatable bag 113 that is insertable therein. Theinflatable bag 113 is provided with aninlet 115 for injecting gas, such as air, into it so as to provide rigidity to itscorresponding container unit 16. One of thesides 32 of thecontainer unit 16 is easily removable so as to fit the correspondinginflatable bag 113. - Referring to Figure 7, there is shown a cross section of the
hull 12 with aninner keel 118 connecting thecontainer units 16 together within the innerhollow section 18 of thehull 12. As shown, theinner keel 118 is connected to eachcontainer unit 16 on one side thereof that is facing thehollow section 18. - Referring to Figure 8, each
air bag 113 faces a screw type port holes 120 that is airtight and accessible from the lower deck through the cabin floor. Alternatively, a vacuum type port hole can also be used.
