         13 . A watercraft comprising:
 a hull;   at least one hydrofoil which is height-adjustable between a position disposed in the region of the hull and a position remote from the hull;   a recess provided in the hull which accommodates the hydrofoil in the position situated in the region of the hull; and   an arm provided on the hull,   wherein the hydrofoil is pivotably attached to the arm about a longitudinal axis and/or is arranged in a telescopically extendable manner in an axial direction of the hydrofoil.   
     
     
         14 . The watercraft of  claim 13 , wherein the arm is telescopically extendable. 
     
     
         15 . The watercraft of  claim 14 , further comprising a drive element arranged on the arm. 
     
     
         16 . The watercraft of  claim 15 , wherein the recess accommodates the drive element and comprises flow channels for an inflow and an outflow of the drive. 
     
     
         17 . The watercraft of  claim 13 , wherein the arm is a pivotal about a pivot axis. 
     
     
         18 . The watercraft of  claim 17 , further comprising a drive element arranged on the arm. 
     
     
         19 . The watercraft of  claim 18 , wherein the recess accommodates the drive element and comprises flow channels for an inflow and an outflow of the drive. 
     
     
         20 . The watercraft of claim  12 , wherein the hydrofoil is arranged in a horizontally or vertically pivotable manner to enable a steering movement. 
     
     
         21 . The watercraft of claim  12 , wherein the hydrofoil comprises a pivotable section. 
     
     
         22 . The watercraft of  claim 21 , wherein the recess accommodates the hydrofoil and the pivotable section in different positions. 
     
     
         23 . A watercraft comprising:
 a main hull;   at least one hydrofoil attached to the main hull and which is height-adjustable between a position disposed in the region of the main hull and a position remote from the main hull;   a recess provided in the hull which accommodates the hydrofoil in the position situated in the region of the hull;   at least one adjustably arranged outrigger configured to accommodate the hydrofoil in at least one position in the recess; and   an arm provided on the main hull,   wherein the hydrofoil is pivotably attached to the arm about a longitudinal axis and/or is arranged in a telescopically extendable manner in an axial direction of the hydrofoil.   
     
     
         24 . The watercraft of  claim 23 , wherein the hydrofoil is pivotably attached to the least one adjustably arranged outrigger. 
     
     
         25 . A watercraft comprising:
 a main hull;   at least one hydrofoil attached to the main hull and which is height-adjustable between a position disposed in the region of the main hull and a position remote from the main hull;   a recess provided in the hull which accommodates the hydrofoil in the position situated in the region of the hull;   at least two adjustably arranged outriggers configured to accommodate the hydrofoil in at least one position in the recess; and   an arm provided on the main hull, wherein the hydrofoil is pivotably attached to the arm about a longitudinal axis and/or is arranged in a telescopically extendable manner in an axial direction of the hydrofoil,   wherein the at least two adjustably arranged outriggers are each configured for movement from a first position arranged adjacent to main hull to a second position arranged beneath the main hull.   
     
     
         26 . The watercraft of  claim 25 , wherein the least two adjustably arranged outriggers are disposed directly adjacent to one another in the position arranged beneath the main hull. 
     
     
         27 . The watercraft of  claim 26 , wherein the least two adjustably arranged outriggers form a common compact hull. 
     
     
         28 . The watercraft of  claim 27 , wherein the common compact hull comprises at least one recess for the hydrofoil. 
     
     
         29 . The watercraft of  claim 25 , wherein the hydrofoil is pivotably attached to the least two adjustably arranged outriggers.
