External inflatable drop stitch stability system for boats

Abstract

An inflatable stability and fender system including high pressure drop stitch D-shaped tubes mounted on a hard sided monohull of a boat or on the side of a dock by extrusions, thru bolting and boat ropes for sealing engagement with the monohull of the boat or the dock.

What is claimed is: 
     
         1 . A stability system for a monohull boat comprising:
 a pair of inflatable D-shaped drop stitch tubes;   an air fill valve positioned along the length of the tube; and   means for attaching one of the inflatable D-shaped drop stitch tubes on either side of the monohull boat.   
     
     
         2 . The system of  claim 1  wherein the means of the attaching the tubes are a plurality of boat rope extensions and rope. 
     
     
         3 . The stability system of  claim 1  further comprising a coupler for connecting a plurality of D-shaped drop stitch tubes end to end. 
     
     
         4 . The stability system of  claim 1  wherein the system further comprises a nose cone positioned on an end of each tube. 
     
     
         5 . A fendering system for a dock comprising:
 an inflatable D-shaped drop stitch tube;   an air fill valve positioned along the length of the tube; and   means for attaching the tube to the dock.   
     
     
         6 . The fender system of  claim 5  wherein the means of attaching the tube to the dock include a plurality of bolt rope extensions and a rope. 
     
     
         7 . The fender system of  claim 5  wherein the inflatable D-shaped drop stitch tube includes a plurality of sections connected end to end by a coupler. 
     
     
         8 . A boat comprising:
 a V-shaped hard sided monohull;   an inflatable drop stitch D-shaped tube mounted on either side of the monohull;   an air fill valve positioned along a top surface of each tube; and   an attachment mechanism positioned along the length of the tube for connecting the tube to each side of the monohull.   
     
     
         9 . The boat of  claim 8  wherein the attachment mechanism is a plurality of boat rope extensions and rope. 
     
     
         10 . The boat of  claim 8  further comprising a coupler for connecting a plurality of D-shaped drop stitch tubes end to end. 
     
     
         11 . The boat of  claim 8  further comprising a nose cone positioned on an end of each tube.
