Watercraft with adjustable tower assembly

Abstract

A watercraft comprising a hull, a roof, a support including a first end coupled to the roof and a second end positioned within the hull, and an actuation assembly coupled to the support. The support is moveable between a first position and a second position in response to activation of the actuation assembly. The support extends into the hull a first distance in the first position and a second distance in the second position. The second distance is larger than the first distance.

What is claimed is: 
     
         1 . An assembly comprising:
 a block including a base and an arm; wherein the base and the arm at least partially define a receiving area;   an eccentric pin positioned within the receiving area; and   a bearing coupled to the base of the block.   
     
     
         2 . The assembly of  claim 1 , wherein the bearing position is adjustable in at least 3 degrees of freedom. 
     
     
         3 . The assembly of  claim 2 , wherein the bearing position is adjustable in at least 4 degrees of freedom. 
     
     
         4 . The assembly of  claim 1 , wherein an end of the arm is releasably clamped to the base by a fastener. 
     
     
         5 . The assembly of  claim 4 , wherein the eccentric pin is rotatable within the receiving area when the arm is unclamped from the base. 
     
     
         6 . The assembly of  claim 1 , wherein the base includes a planar surface that abuts the bearing. 
     
     
         7 . The assembly of  claim 6 , wherein the base includes a boss extending from the planar surface, and wherein the bearing is rotatable about the boss. 
     
     
         8 . The assembly of  claim 7 , wherein a fastener couples the bearing to the boss. 
     
     
         9 . The assembly of  claim 1 , wherein the eccentric pin includes a barrel portion that abuts the arm and the base. 
     
     
         10 . The assembly of  claim 9 , wherein the arm is adjustably positioned along the barrel portion. 
     
     
         11 . The assembly of  claim 10 , wherein the eccentric pin further includes a cylinder portion extending from an end of the barrel portion, wherein a cylinder axis of the cylinder portion is spaced from a central axis of the barrel portion. 
     
     
         12 . The assembly of  claim 11 , wherein the eccentric pin includes a hex portion extending from the cylinder portion. 
     
     
         13 . The assembly of  claim 12 , wherein the hex portion includes a detent. 
     
     
         14 . The assembly of  claim 11 , further comprising a bracket having an aperture; wherein the cylinder portion is at least partially positioned within the aperture. 
     
     
         15 . The assembly of  claim 14 , wherein a first end of the eccentric pin is supported by the bracket, and a second end of the eccentric pin is supported by a hull panel. 
     
     
         16 . The assembly of  claim 15 , further comprising a fastener positioned between the eccentric pin and the hull panel. 
     
     
         17 . The assembly of  claim 16 , wherein the bracket is secured to the hull panel with a bracket fastener. 
     
     
         18 . The assembly of  claim 1 , wherein the bearing includes an arcuate surface. 
     
     
         19 . The assembly of  claim 18 , wherein the arcuate surface is cylindrical. 
     
     
         20 . The assembly of  claim 1 , further comprising a support including a groove; wherein the bearing is at least partially positioned within the groove.
