Not a universal sleeve. Not a stretch fit. A pattern engineered to the millimeter for your specific Polyform model — installed deflated and inflated to a seamless, molded result.

Polyform F-Series
F-Series Fender Covers — F-02 Through F-13
The F-Series is the most widely used cylindrical fender lineup on the water — Polyform's flagship twin-eye design built for vertical or horizontal hanging. It spans twelve sizes from the compact F-02 up to the megayacht-scale F-13, with multiple-ribbed reinforced ropeholds at both ends. Every model has a unique diameter and length, and every one has its own precision dieline in our library — your cover is cut to the exact specifications of your model, not approximated to a nearest size.
Each cover is precision-cut from 5mm closed-cell neoprene — UV resistant, saltwater resistant, and backed by a 3-year warranty. No drawstrings, no Velcro. Available in custom-printed designs or standard solid colors.
| Model | Size | Common Vessels |
|---|---|---|
| F-02 | 4.5" × 11.5" | 20–30 ft boats |
| F-1 | 6.5" × 15" | 20–25 ft boats |
| F-2 | 8.5" × 20.5" | 20–30 ft boats |
| F-3 | 10.5" × 26" | 20–30 ft boats |
| F-4 | 11.5" × 30.5" | 30–35 ft cruisers |

| F-8 | 21" × 60" | 50–70 ft yachts, sportfishers |
| F-10 | 24" × 68" | 60–70 ft yachts, commercial |
| F-11 | 28.5" × 81" | 60 ft to megayacht |
| F-13 | 32" × 95" | 70 ft and up, megayachts & commercial |
Polyform G-Series
G-Series Fender Covers — G-1 Through G-6
The G-Series is Polyform's twin-eye utility fender — a one-piece molded cylinder with reinforced ropeholds at both ends and molded-in ribs for abrasion resistance, available in a wide range of Polyform colors. The lineup spans six sizes from the compact G-1 for tenders and PWC up to the G-6 for 35–40 ft motoryachts. Each model gets its own dieline cut to the exact diameter and length — the smooth profile means even a small variance in fit would be immediately visible, which is why universal sizing fails here.
Each cover is precision-cut from 5mm closed-cell neoprene — UV resistant, saltwater resistant, and backed by a 3-year warranty. No drawstrings, no Velcro. Available in custom-printed designs or standard solid colors.
| Model | Size | Common Vessels |
|---|---|---|
| G-1 | 3.5" × 11.5" | Up to 10 ft — dinghies, tenders, PWC |
| G-2 | 4.5" × 15.5" | 10–15 ft boats |
| G-3 | 5.5" × 19" | 15–20 ft boats |
| G-4 | 6.5" × 22" | 20–25 ft boats |
| G-5 | 8.5" × 27" | 25–35 ft cruisers, sportfishers |
| G-6 | 10.5" × 30" | 35–40 ft cruisers, motoryachts |
Polyform A-Series
A-Series Buoy Covers — A-0 Through A-7
The A-Series is Polyform's all-purpose round buoy — the product that launched the company and the signature blue-ropehold design more fishermen use than all other buoys combined. It works equally well as a corner fender, bow protection, rafting fender, or working mooring buoy, with eight sizes spanning the 8-inch A-0 up to the 38-inch A-7. Covering a sphere requires a different pattern approach than a cylinder, and our A-Series dielines account for the full curvature across every model.
Each cover is precision-cut from 5mm closed-cell neoprene — UV resistant, saltwater resistant, and backed by a 3-year warranty. No drawstrings, no Velcro. Available in custom-printed designs or standard solid colors.
| Model | Size | Common Vessels |
|---|---|---|
| A-0 | 8" × 11.5" | Up to 15 ft — small boats, PWC |
| A-1 | 11.5" × 15" | 15–30 ft — corner & bow protection |
| A-2 | 14.5" × 19" | 30–40 ft cruisers, mid-size yachts |
| A-3 | 18" × 23.5" | 40–50 ft yachts, heavy corner protection |
| A-4 | 22" × 28" | 50–60 ft yachts, commercial vessels |
| A-5 | 27" × 34" | 60–70 ft yachts, commercial use |
| A-6 | 31.5" × 40" | 70 ft and up — superyachts, commercial |
| A-7 | 38" × 47" | Superyachts, oil rigs, commercial moorings |
Polyform HTM-Series
HTM-Series Fender Covers — HTM-1 Through HTM-5
The HTM-Series (hole-through-middle) is a heavy cylindrical fender with the mounting line passing straight through the center — reinforced tube ends prevent the line from pulling through, and the fender can rotate freely around the line to absorb impact from any angle. The lineup spans five sizes from HTM-1 for 20-ft boats up to HTM-5 for 50+ ft yachts and commercial vessels. Our HTM dielines account for the through-middle geometry and reinforced tube-end profile specific to each model.
Each cover is precision-cut from 5mm closed-cell neoprene — UV resistant, saltwater resistant, and backed by a 3-year warranty. No drawstrings, no Velcro. Available in custom-printed designs or standard solid colors.
| Model | Size | Common Vessels |
|---|---|---|
| HTM-1 | 6.3" × 15.7" | 20–25 ft boats |
| HTM-2 | 8.7" × 20.9" | 25–30 ft cruisers |
| HTM-3 | 10.6" × 26.8" | 30–40 ft cruisers, sportfishers |
| HTM-4 | 13.5" × 33.5" | 40–50 ft motoryachts |
| HTM-5 | 15.4" × 41.7" | 50+ ft yachts, commercial |
Polyform LD-Series
LD-Series Buoy Covers — LD-1 Through LD-4
The LD-Series is Polyform's patented low-drag buoy — introduced in 1989 for the commercial crabbing and fishing industries, where it reduces drag by as much as 80% compared to standard round buoys for faster, safer pickups in heavy seas. The same shape also makes excellent fore-and-aft rafting protection on recreational vessels. The lineup spans four sizes from the 8-inch LD-1 to the 14-inch LD-4. The tapered round profile requires a fully curved pattern — each LD model has its own dieline engineered to wrap cleanly without bunching at the poles.
Each cover is precision-cut from 5mm closed-cell neoprene — UV resistant, saltwater resistant, and backed by a 3-year warranty. No drawstrings, no Velcro. Available in custom-printed designs or standard solid colors.
| Model | Size | Common Vessels |
|---|---|---|
| LD-1 | 8" diameter | 20–30 ft — corner buoys, small vessels |
| LD-2 | 10" diameter | 30–35 ft cruisers, mid-size powerboats |
| LD-3 | 12" diameter | 40–50 ft cruisers, heavy corner protection |
| LD-4 | 14" diameter | 50–60 ft yachts, commercial use |
Polyform NF-Series
NF-Series Fender Covers — NF-3 Through NF-5
The NF-Series is Polyform's heavy-duty recreational cylindrical fender — a twin-eye design with multiple-ribbed reinforced ropeholds at both ends and molded-in ribs for abrasion resistance. Built for smaller boats that need commercial-grade strength in locks, tidal areas, and high-stress moorings. Polyform US currently produces NF-3, NF-4, and NF-5, covering 10-ft boats up through 35-ft cruisers, and each model gets its own precision-cut dieline.
Each cover is precision-cut from 5mm closed-cell neoprene — UV resistant, saltwater resistant, and backed by a 3-year warranty. No drawstrings, no Velcro. Available in custom-printed designs or standard solid colors.
| Model | Size | Common Vessels |
|---|---|---|
| NF-3 | 5.5" × 19" | 10–20 ft boats |
| NF-4 | 6.5" × 22" | 20–25 ft boats |
| NF-5 | 8.5" × 27" | 25–35 ft cruisers |
