Abstract

Improvements applied to a conventional sailboard which make possible the utilisation of the board in the conventional manner, sail held by hand, sail integral with a fixed mast, device equipped with floats (I) equipped with anti-bather fenders (16), this device is constituted by elements which are fixed or removable and integral with the board ex-factory with the aid of bolts inserted into ferrules which pass through the board, for current boards of bolts inserted into the centre-board well (25), of small sleeves inserted into the hole of the safety end, of straps (12), and ferrules (15) and a sliding seat make possible the use of oars, and an alternative embodiment is equipped with removable lateral arms and is without floats (I).

Description

i 2663288 To date, windsurfing is only powered by

  a sail held in the hand, without appreciable benefit

  for the health of the user most city dwellers who suffer

  frent already sedentary The present invention allows the use of a windshield in a conventional manner and its propulsion using paddles or paddles, which can only be beneficial for the health of

  the user, and in the absence of wind the board is used

  sand Your board with floats I allows you to learn

  It is easier and less risky to weave

  hand holding This device also allows the use of a trimaran using a fixed mast, the steering can be carried out using a rudder, or rowing, 6, a paddle T 5 These devices are removable and removable, the board

  can therefore be used in a conventional manner, and its transp-

  ort is easy on the roof of a car

  The invention will be better understood from the description below.

  The present device consists of longitudinal bars I straddling transverse bars $, Figures I,?, 3 plate I; which allows the sliding and the maintenance of a seat I provided with casters I 9 This seat is maintained by means of hooks made of flat iron and provided with casters which roll on the lower base of the

  bars I 3, other rollers roll on the upper part

of these bars I 3.

  This seat is provided with a removable backrest which fits into O O ferrules integral with the seat, ankles ensure its fixability, likewise ankles threaded in the bars I 3 can immobilize this seat

  A belt secured to the backrest may be provided, or the use

  reader can be provided with a belt secured to a rope I 5 with knots secured to a bar IX, a rope which will prevent him from seeing his boat go without him if he falls into the water T e device of figure I of plate I for
