<h3>Polyform US: Setting the Global Standard for Marine Protection</h3><p>For boaters who refuse to compromise on hull protection, <strong>Polyform US</strong> has spent decades earning a reputation as one of the most trusted names in marine fenders and buoys. Headquartered in Kent, Washington, Polyform US designs and manufactures its products right here in the United States — a commitment that shows in every detail, from material selection to the iconic blue rope-hold that has become a hallmark of the brand worldwide.</p><h3>A Legacy Built on the Water</h3><p>Polyform&apos;s story stretches back more than 70 years, during which it has supplied not just recreational boaters but commercial fishermen, marina operators, and even military and coast guard fleets. Whether tied up in a quiet freshwater slip or riding out the swells of a commercial fishing ground, Polyform products are engineered to perform where lesser gear fails. That global trust isn&apos;t accidental — it is the product of rigorous manufacturing standards, durable marine-grade vinyl construction, and an unwavering focus on even wall thickness and reinforced rope-holds across every product line.</p><h3>Fenders for Every Vessel Size</h3><p>At the core of the Polyform lineup are its industry-leading <a href="/7498-polyform-fenders-200396">boat fenders</a>, offered in multiple series to suit vessels of all sizes. The <strong>G-Series</strong> is the go-to all-around cylindrical fender for trailered boats and permanent moorings alike, while the <strong>F-Series</strong> steps up for larger vessels demanding serious hull protection. The <strong>HTM (Hole-Through-Middle) Series</strong> offers center-mount versatility for boats in the 30- to 40-foot range, and the rugged <strong>NF-Series</strong> is built as a single-piece heavy-duty fender with molded-in ribs for maximum abrasion resistance in high-stress docking environments like tidal areas and boat locks. For smaller crafts, the compact <strong>S-Series</strong> doubles as both a fender and a mooring buoy for PWCs and runabouts.</p><h3>Buoys for Marking, Mooring, and the Water Sports Course</h3><p>Beyond fenders, Polyform&apos;s <a href="/7498-polyform-mooring-fishing-buoys-200692">mooring and fishing buoys</a> are relied upon by mariners around the world. The legendary <strong>A-Series</strong> all-purpose buoy — the product that launched the Polyform brand — remains a staple for commercial fishermen, pot-and-trap operations, and general mooring use, praised for its ability to handle the most adverse conditions in ocean, sea, river, or lake environments. The <strong>CC-Series</strong> steps in for larger commercial and mooring applications where maximum buoyancy and durability are essential.</p><p>For water sports enthusiasts, Polyform also produces the <a href="/7498-polyform-slalom-buoys-200968">WS-1 Slalom Buoy</a>, which is commonly paired with the S-Series as a complete course-marker package for competitive and recreational slalom courses.</p><h3>Accessories That Complete Your Docking Setup</h3><p>Polyform rounds out its lineup with a full range of docking accessories. The <a href="/7498-polyform-fender-covers-200392">fender covers</a> — available in the purpose-built <strong>EFC Series</strong> woven polyester design — protect both your hull and your fenders from abrasion and UV degradation, extending the life of the entire system. To organize and secure your fenders while underway or at the dock, Polyform&apos;s <a href="/7498-polyform-fender-holders-200393">fender holders</a> keep everything neatly in place without the tangle of loose lines. Together, these accessories reflect Polyform&apos;s philosophy that reliable marine protection is a complete system — not just a single product.</p>

I've worked easier sites, but overall fairly straitforward. Would buy from again.

Very easy to shop. Great price!!!!

thanks for great price and free shipping

Great priced product

I ordered a Thule 872XT 44" Fairing from them because they had the best deal on a new one and their shipping was fair. I live on Long Island N.Y. and got my order in 2 days! I did not expect the fast shipping but i am very thankful for it! I received an email when i paid, when my order shipped and then when my order was delivered to my door. I never heard of this online vendor until i was searching for the Thule but they had very positive reviews so i had little to lose. I will look to them first for future needs. A+!

Great

So far great, no problems. Received order on 04/21/2015
