attwood car-top canoe carrier kit Canoe Carrier — 4 Foam Gunwale Blocks, 20 ft Rope and Adjustable Strap

Attwood 11437-7 is a complete car-top canoe carrier kit that includes snap-on foam gunwale supports, durable rope with S-hooks, and adjustable poly web straps to safely secure a canoe to most vehicle roofs.

If you want a simple, reliable way to move a canoe without a permanent roof rack, this kit supplies the basic hardware to protect both boat and car while you travel. Designed by Attwood — a century-old marine manufacturer — the 11437-7 pairs soft foam contact points with tough fastening components for straightforward setup, compact storage, and broad compatibility with sedans, hatchbacks, and many SUVs.

How does this kit protect my car’s roof and the canoe during transport?

The kit uses four snap-on foam blocks that cradle the canoe’s gunwales, keeping hard plastic or metal parts off the vehicle paint. The foam absorbs vibration and prevents direct rubbing, while the straps and rope maintain steady pressure to stop shifting in traffic or at highway speeds.

• Four foam blocks snap onto the canoe gunwales to cushion contact points.
• Poly web straps with adjustable buckles compress the canoe to the roof without over-tightening.
• Vinyl-coated clips and S-hooks protect vehicle finishes where lines touch bumpers.
• 20 feet of polypropylene rope provides bow and stern tie-down reach for most cars.

What hardware comes in the box and what are the materials?

The kit includes four molded foam supports, one poly web strap with an adjustable buckle and vinyl-coated clips, 20 feet of polypropylene rope, and two S-hooks. All components are chosen for weather resistance and ease of use: closed-cell foam resists water and abrasion, polypropylene rope sheds moisture, and the poly web strap resists UV and mildew.

• 4 snap-on foam gunwale blocks (closed-cell foam)
• 1 poly web strap with adjustable buckle and vinyl-coated clips
• 20 ft polypropylene rope and 2 S-hooks for bow/stern tie-downs
• Materials selected for corrosion and UV resistance

How do I install the carrier kit on my car step-by-step?

Installation is tool-free for most vehicles. Set the foam blocks on the canoe gunwales, position the canoe on the vehicle roof, secure the poly strap over the center of the canoe and tighten the buckle, then run the polypropylene rope from bow and stern to the bumpers, fastening with the S-hooks.

• Snap foam blocks onto canoe gunwales at four points.
• Lift and position canoe on vehicle roof centered side-to-side.
• Loop poly web strap over canoe, clip and tighten the adjustable buckle.
• Attach rope from bow/stern to bumpers with S-hooks; re-check tension and alignment.

Will this fit my vehicle and different canoe sizes?

The kit is intended for temporary, universal use on cars without fixed roof racks. The foam blocks and 20-foot rope accommodate most recreational canoe lengths, and the adjustable web strap provides flexible clamping. However, very wide canoes or vehicles with unusual roof profiles may need additional straps or professional racks for optimal safety.

• Works with most sedans, hatchbacks, and many SUVs for short- to mid-length canoes.
• Adjustable strap and long rope allow flexible placement and tie-down options.
• For very wide or heavy canoes, consider factory roof racks or a dedicated carrier system.

Who is this for: The Attwood 11437-7 is aimed at paddlers who want a compact, low-cost solution to carry a canoe occasionally without permanent roof racks. It’s a good match for weekend adventurers, renters, or anyone transporting a canoe for short trips who values simple install, protective foam contact, and weather-resistant hardware from a trusted marine brand.
