• At the bearing surface 200 may be associated a second ramp surface 202 formed in the boss 20 and extending from the deck of the boat to the temporary bearing surface 200.
• This ramp surface 202 considering the trajectory of the arm on the boss is opposite to the previous one.
• the bearing surface 200 forms the summit zone of the boss.
• This second ramp surface 202 is provided to slidably receive the structure 3 of the device 1 and guide the movement of the latter between the storage position on the bridge and the bearing position on the temporary support surface 200 .
• the vertical shaft 181 is able to removably receive a support member 21 of the device 1, this support member occupying on the vertical shaft a lower position relative to that occupied by the cradle or cradles and a higher position relative to the bridge.
• This support member 21 constitutes a removable obstacle to the translational movement of the device 1 down and along the sheath, during the manual folding operation of said device on the bridge.
• this temporary support member is constituted by a pin 21 and the shaft 181 will be provided with a diametrical through bore for receiving this pin.
• the device 1 is supported by the sleeve 19 on the support member 21.
• a traction member 22 in the form of a link, fixed to the supporting structure 3, away from the axis 181 by a fastener 221.
• This link 22 may also be engaged in a ring 220 fixed to the boat 2 and occupying, on the boat, a position close to that occupied by the fastener 221 of the link 22 to the structure 3, when the device 1 is folded on the bridge.
• This second traction link 23 may also provide a second traction link 23 to deploy the device and bring it in place by its structure 3 in the cradle or 15.
• This second traction link 23 will be fixed by a fastener 231 to the structure 3 of the device 1 away from the shaft 181, and will be engaged in a guide ring 232 fixed for example to the foot 151 supporting the cradle 15 furthest from this shaft 181.
• the two links 22, 23 are actuated manually or by a winch motor system for example or other traction system.
• the system 18 as understood participates in the maintenance of the device 1 on the boat 2.
• the maintenance of the device on the boat in the folded state may be completed by a stowage made by any known means.
• the boat 2 may be equipped with a removable rig preferentially foldable on the deck.
• the rigging in the folded state occupies a lateral position in the vertical geometric plane PP 'opposite to the position occupied by the device 1 in the folded state on the deck of the boat .
• This rig includes a mast 24 preferably tubular and a sail not shown.
• the boat will be provided with a mast foot 26 designed to cooperate in shape interlocking with the base of the mast 24, this mast foot 26 being secured to an element of the boat by a connection of the ball type 261.
• this ball joint may be constituted by an elastomer diabolo of the type used to secure the sailboards masts to said boards.
• the boat will be provided with a mast support 27 projecting upwardly, having at its lower end a fork 271 in which the mast 24 is engaged.
• mast 24 will be locked against the mast support 27 by a halyard 28 appropriate.
• the mast support 27 will preferably be removable. In the position of use, the mast support 27 will be engaged by its lower part in a well formed in the hull of the boat.
• the halyard 28 will be fixed by one of its ends to an anchor ring
• a deflection element 282 fixed at the upper end of the mast support 24 will be engaged in a guide element 283 under form of ring fixed on the deck of the boat 2 and then will be engaged in a blocking element 284 which may be a cleat or a blocker, which can be fixed to the mast support.
• This arrangement by the tension of the halyard 28 ensures the immobilization of the mast 24 in the form of fork 271 that has the mast support 27, ensures immobilization in translation of the mast 24 along its longitudinal axis but also ensures the immobilization of the mast support 27 in its well.
• the device 1 will be made of lightweight materials to present a weight compatible with manual manipulation by the user and this during navigation.
