Lido 14 Centerboard with Integral Arm

Abstract

A centerboard for a boat, having a body with a head disposed at its proximal end and an arm emanating therefrom. The centerboard is of unitary construction, namely wherein the body, the arm, and the various specific features associated therewith, all consist of a single piece or portion of uniform material.

I claim: 
     
         1 . A centerboard comprising:
 a body; and   an arm extending from the body,   wherein the body and the arm consist of a unitary construction.   
     
     
         2 . The centerboard of  claim 1  wherein the body comprises:
 a head defined at a proximal end of the body; 
 a tip defined at a distal end of the body; and 
 a hydrodynamic section defined between the head and tip. 
 
     
     
         3 . The centerboard of  claim 2  wherein the head defined at the proximal end of the body comprises:
 a first edge that is disposed parallel to a longitudinal axis of the body; and 
 a second edge comprising a curvature configured to provide a quarter-circle profile, 
 wherein the arm comprises a curvature configured to approximately match the curvature of the second edge. 
 
     
     
         4 . The centerboard of  claim 1  further comprising a tab disposed on a proximal end of the arm. 
     
     
         5 . The centerboard of  claim 4  wherein the tab extends from the proximal end of the arm in a parallel direction relative to a longitudinal axis of the body. 
     
     
         6 . The centerboard of  claim 1  further comprising a plurality of gybe bumps disposed on the head. 
     
     
         7 . The centerboard of  claim 6  wherein at least one of the plurality of gybe bumps is disposed on each of a port and a starboard longitudinal surface of the head. 
     
     
         8 . A centerboard consisting of unitary construction comprising:
 a body; and   an arm integrated with the body.
