Benefits of technology
"The present invention is about modified vessels that consist of multiple yachts arranged in train sequences or parallel to each other. The first embodiment involves permanently modifying each yacht to be a part of the multi-hull vessel. In another embodiment, each yacht is equipped with a specific universal connecting device that allows for easy disconnection and reconnection of the yachts. This transformation can be done with old-model or new-built yachts. The technical effects of this invention include improved efficiency, flexibility, and adaptability for multi-hull vessels, as well as increased safety and comfort for yachts in use."
Problems solved by technology
Further, the price for such a yacht is much low in comparison with large ocean yacht; but this yacht capacity, its internal space and facilities are limited by the size of the vessel.
Such multi-hull vessels allow enlarging its capacity, but they inherit all disadvantages of parallel-hull vessels, such as low maneuverability, high hydrodynamic drag (in comparison with single-hull vessel), etc.
Also, even though the initial stability of parallel-hull vessels is high, it starts diminishing when such vessel is listing, unlike single-hull yachts having a keel; and when list of parallel-hull vessels reaches some relatively small angle (40-60 arc degrees), this catamaran becomes capsized.

Embodiment Construction
[0033]There are a number of variants of embodiments of such multi-hull sequentially-combined sailboats or motorboats. One of them is shown on FIG. 1b. It is just permanent or temporary connection of individual single-hull vessels in sequences. Another embodiment (FIG. 3) requires cutting and permanent merging two hulls in the single one.
[0034]The first variant of multi-hull sailboat (or motorboat) of the preferred embodiment comprises a number of individual single-hull vessels that are sequentially arranged and joint together by means of a pivoted connecting devices to provide a train-like multi-hull vessel, wherein each vessel can be turned about another vessel to which it is pivotally connected on small angle in vertical and horizontal planes. It provides flexibility for the multi-hull vessel in such a way that allows it going round ocean waves; and, because the relative velocity vector is directed along axis of each hull, such train-like assembly is going round a corner so dimini...

A multi-hull sailboat or motorboat that are made of a number of single-hull vessels in the process of modification or utilization of old yachts, wherein said multi-hull vessel can be configured as a pivoted train-like combined vessel, as a permanently-merged vessel or can be configured as a catamaran or triamaran. Also, said multi-hull sailboat or motorboat can be made of a number of new single-hull vessels equipped by a universal connecting device.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This Application is related to U.S. patent application Ser. No. 12 / 548,538.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not Applicable.THE NAMES OF THE PARTIES TO A JOINT RESEARCH AGREEMENT[0003]Not Applicable.INCORPORATED-BY-REFERENCE OF MATERIAL SUBMITTED ON A COMPACT DISK[0004]Not Applicable.FIELD OF THE INVENTION[0005]The present invention relates to multi-hull vessels, and more particularly to rebuild or modified boats having combined hull.DESCRIPTION OF THE RELATED ART[0006]Small and medium-size sailing boats with single hull, such as Alberg 30 yacht and similar, are often used for sport and leisure. Such vessels are relatively small and light enough to be transported on a privet car or track trailer. Further, the price for such a yacht is much low in comparison with large ocean yacht; but this yacht capacity, its internal space and facilities are limited by the size of the vessel. Therefore, yacht designer t...
