Our smallest 9" diameter inflatable fender is 24" long and is ideal for boats under 30 feet. 
 
All of our fenders have strong, welded seams, reinforced D-Rings on both the top & bottom of the fender, strong PVC fabric and carry our North Atlantic Inflatables 5-year warranty!  They are easy to inflate quickly and deflate fast for compact storage.
 
Our fenders have a Haulkey-Roberts air valve and use a foot pump (sold separately) to get the ideal pressure of 3-5 psi.
