Abstract

The dismantlable catamaran uses two surfboard-type floats as hulls. Above the upper surface of each of these, near the ends, sockets-pref. rectangular in cross-section - are mounted horizontally, in parallel and an equal distance apart. Crossbeams (1) fit into these sockets and are held by cotters (2) secured by split-pins. The forward beam carries a mast mounting (5). Flat lugs on an aluminium tube frame (6) for the decking allow this also to be secured by the cotters.

Description

Zerlegbares Doppelrumpfboot auf Surfbrettbasis(SURFCAT)Dismountable double hull boat based on surfboard (SURFCAT)

Die Erfindung betrifft ein Doppelrumpfboot mit Surfbrettern als Schwimmkörper.The invention relates to a double hull boat with surfboards as a floating body.

Aufhabe der rfindung ist ein Doppelrumpfboot eines völlig neuen Typs, d.h.mit zwei gleichen Surfbrettern als Schwimmkörper,da eine solche Konstruktion einfach zu tranportieren,zu lagern sowie in wenigen Minuten selbst von laien und ohne llerkzeuge auf -bzw.abgebaut werden kann.The object of the invention is a double hull boat of a completely new type, i.e. with two identical surfboards as floats, as such a construction easy to transport, store and even in a few minutes by laypeople and Can be assembled and disassembled without tools.

Auf jedem Surfbrett sind zwei quer zur Fahrtrichtung und in Abstand stehende vorzugsweise rechteckige Steckmuffen angebracht,diese sind wiederun über eine Halterung fest mit dem Surfbrett verbunden.On each surfboard there are two across the direction of travel and at a distance standing, preferably rectangular socket sleeves are attached, these are in turn over a bracket firmly connected to the surfboard.

Durch diese Steckmuffen wird erreicht,das die aufzunehmende Querstrebe nur eingeschoben weden muss und mittls eines Steckbolzens mit Sicherung absolut rnit den Schwimmkdrper verbunden ist.Through these plug-in sleeves it is achieved that the transverse strut to be accommodated only has to be pushed in and absolutely secured by means of a socket pin is connected to the floating body.

Die Erfindung: ist nachstehend anhand der Zeichnung näher erläutert.The invention: is explained in more detail below with reference to the drawing.

Es zeigen: Figur 1 ein Ausführungsbeispiel eines erfindungsgemässen Doppelrumpfbootes in Draufsicht sowie in schematischer Darstellung.The figures show: FIG. 1 an exemplary embodiment of an inventive Double hull boat in plan view and in a schematic representation.

Figur 2 einen Bereich A von Figur 1 in demgegeniiber vergrösserter Darstellung.FIG. 2 shows an area A from FIG. 1 in an enlarged view Depiction.
