Fifty-plus years of production have made the Polyform F Series a benchmark in inflatable vinyl fenders. The classic European twin-eye cylinder construction has earned its place on vessels from weekend runabouts to oceangoing yachts by delivering consistent wall thickness, molded-in ribbing, and reinforced ropeholds across a size range few other manufacturers can match. Twelve sizes span boats from 20-foot trailered boats all the way up to vessels exceeding 70 feet.

Features:

• Even wall thickness throughout for maximum strength and long-term durability
• Molded-in ribs add structural strength and resist abrasion at the dock
• Reinforced ropeholds handle repeated loading without fatigue
• Twin-eye design supports both vertical and horizontal rigging
• Suited for trailered boats and permanent protected moorings
• Proprietary Polyform valve engineered for years of reliable service
• One-piece construction with no seams to fail
