Surfboard

Abstract

The present invention relates to a surfboard formed according to a longitudinal configuration of varying widths, comprising an area ( 1 ) in the front part and an area ( 2 ) in the rear part determining respective transverse widenings with respect to a narrower area ( 3 ) of the central part, with a determined ratio between the maximum widths (H 1 and H 2 ) of the areas ( 1 and 2 ) and the minimum width (H 3 ) of the area ( 3 ), as well as a determined ratio of the location of said widths (H 1 , H 2 and H 3 ) with respect to the total length (L) of the board.

1 . A surfboard of the type having an elongated configuration with symmetry with respect to the longitudinal shaft, characterised in that it longitudinally determines a configuration of varying widths, with rounded contours and progressive curve transitions between the different widths, comprising an area ( 1 ) in the front part and an area ( 2 ) in the rear part determining respective transverse widenings with respect to a narrower area ( 3 ) of the central part, between the areas of which a ratio of widths is met such that the minimum width (H 3 ) of the central area ( 3 ) is comprised between 81% and 85% of the maximum width (H 1 ) of the front area ( 1 ) and between 93% and 97% of the maximum width (H 2 ) of the rear area ( 2 ), the maximum width (H 1 ) of the front area ( 1 ) being located at a distance (L 1 ) from the rear end which is comprised between 76% and 80% of the total length (L) of the board, the minimum width (H 3 ) of the central area ( 3 ) at a distance (L 3 ) from the rear end which is comprised between 35% and 42% of the total length (L) of the board, and the maximum width (H 2 ) of the rear area ( 2 ) at a distance (L 2 ) from the rear end which is comprised between 15% and 18% of the total length (L) of the board, meanwhile this width (H 2 ) is located comprised between 20% and 23% of the total length (L) of the board. 
     
     
         2 . The surfboard according to  claim 1 , characterised in that the minimum width (H 3 ) of the central area ( 3 ) is located at a distance (L 3 ) from the rear end of the order of 38% of the total length (L) of the board.
