Carrying a Kayak Without a Roof Rack: Foam Blocks and Pads

Choose a complete foam-block or padded-support kit only after checking its instructions against your car, kayak and journey. Malone and NRS publish arrangements for roofs without crossbars, which support a carrier. Their blocks need load straps and lines tying the bow (front) and stern (rear) to the vehicle.¹²

This page summarizes published safety guidance. It is not a substitute for instruction, and conditions on your water may differ. Check the current rules for the state and water you paddle.

Key Takeaways

Check vehicle permission before relying on a kit’s load rating.
Match the kit’s roof, door and journey conditions to your car.
Use the complete strap arrangement specified for your kit.
Secure both ends of the kayak to the vehicle.
Stop and recheck at the maker’s stated interval.

Check your car and boat first

Read the vehicle manual alongside the kit instructions. Check roof material, door openings and strap routing. For EasyTop, Yakima prohibits straps over side-curtain airbag openings—the areas along the cabin’s roof edges where those airbags deploy and requires installation to follow both vehicle and product instructions. Resolve uncertain fit with the makers before loading.³

The lowest applicable load limit wins. A kit rating does not grant permission to load your roof. Count supports and accessories as well as the boat toward the vehicle’s limit; see roof load limits explained.³

Malone MPG155: confirm the journey conditions

Malone’s Standard Kayak Foam Block Kit, MPG155, carries one kayak and has a 55-pound (about 25-kilogram) load capacity.⁴

Its linked PDF visibly confirms the strap routing and bow and stern tie-downs described below. It also confirms a recheck after 5 miles. Other text is covered and unreadable on the rendered pages. Extracted text gives a 250-mile (about 402-kilometer) limit and prohibits blocks on a sunroof (a roof window panel). Those restrictions’ current applicability remains unconfirmed. Ask Malone to clarify. The uncertainty does not authorize longer trips or sunroof placement. The rainwater-entry and removal rules come from a separate warning linked on Malone’s product page.¹⁴

For bare-roof use, Malone says to clean the roof and block bottoms, place blocks near the roof’s front and rear, and adjust them until each supports an even share of the kayak’s weight. Open the doors, route both load straps over the kayak, and buckle them inside. Confirm both straps are tight and secure.⁴¹

Malone requires bow and stern safety lines. Attach each S-shaped hook to a tow ring (a towing attachment loop) or another sturdy vehicle body part, and tie to a strong boat attachment point. Test knot strength by pulling, add a second safety knot, and secure both lines. Check that the kayak is firmly attached.⁴¹

Here, wet straps are rain-soaked load straps that pass over the kayak and buckle inside the car. Rainwater can run down them into the cabin. Malone says to remove the foam-block kit and straps from the vehicle after every use. Review instructions and register the warranty before first use; incorrect use of safety lines voids Malone’s warranty and liability.⁴⁵

NRS Deluxe kit: a different strap arrangement

NRS’s Deluxe Kayak Car Rack Kit supports blocks placed directly on the roof. Its product page and linked instructions publish no numeric weight or trip-distance limit. The instructions call for frequent strap checks without specifying miles or minutes. Its linked instructions first secure both blocks to the kayak with straps. Clean debris from roof and blocks, then position them near the vehicle’s front and rear for even weight distribution.⁶²

The center strap passes over the kayak and through open doors on both sides, with its buckle inside. Keep it clear of the driver’s view and distractions.²

NRS hooks bow and stern straps to towing loops or the frame at each bumper end. Pass the cam buckle—the fitting that grips the strap when tightened—through the kayak’s grab loop—the loop used to grip the boat’s end—and wrap the strap twice around its carry handle, the handhold used to lift the boat. Tighten evenly until the blocks compress slightly. Only the blocks should touch the roof.²

NRS also specifies a few strap twists before connecting the buckle to reduce vibration. Check tension frequently to protect painted surfaces.²

Yakima EasyTop: conditions for existing owners

Yakima’s US EasyTop page is archived as “2017–2024.” Treat it as an example for existing owners. Its instructions specify maximums of 80 pounds (36 kilograms), 36 inches (91 centimeters) across the load and 14 feet (4.3 meters) of boat length.⁷³

EasyTop excludes sliding doors, falcon and gull-wing doors (doors that open upward from the roof), and panoramic glass roofs (large glass panels covering much of the roof). Never place it directly on a sunroof or moonroof (roof window panels). Clean the roof, open the doors and space the supports at least 24 inches (61 centimeters) apart.³

Route the integrated support straps inside, buckle them, pull firmly and secure loose ends in their loops. Center the boat. Use the separate HD load straps through loops matching its width and through the end rings; secure their loose ends too.³

For long loads, Yakima instructs you to use ropes to tie them to the vehicle’s front and rear. It requires its separately sold HoodAnchor accessory, which provides a rope attachment point, where the vehicle lacks those points.⁷³

Remove EasyTop before driving in rain, as Yakima instructs to prevent water entering along the straps. Keep the load low and evenly distributed. Follow its loading-surface restriction against substantial overhang. Supports must not project beyond roof gutters—the drip channels along the roof edges; for vehicles without them, consult applicable rules.³

When to choose a rack and cradles

Your boat’s instructions also matter. Wilderness Systems permits foam blocks for short-distance or lower-speed transport of its boats, requires adequate block width, and cautions that blocks are less secure than crossbar racks. Its FAQ publishes no mileage or speed threshold defining “short-distance” or “lower-speed.” Bow and stern must attach directly to the vehicle.⁸

For its composite kayaks—boats made from reinforced materials such as fiberglass—Wilderness Systems requires transport with the hull, or boat body, facing down in cradles—shaped supports for the boat. Its foam guidance is not blanket approval for every boat.⁸

Wilderness Systems warns against straps tight enough to distort the hull and against elastic shock cords or bungees. Its advice to tie the ends loosely is for crossbar racks, where end lines are an additional margin of safety. For foam blocks, Wilderness Systems says it is essential to tie the bow and stern directly to the vehicle, and its crossbar advice does not replace a foam-block kit’s own instructions.⁸

If you cannot meet both boat and kit conditions, choose another compatible system. Compare options in kayak roof racks compared.

Check before driving, then stop and recheck

Incorrect attachment can cause fatal accidents. Malone directs you to a professional installer if instructions are unclear or you lack installation experience. Inspect attachments for adjustment, wear and damage before use and periodically afterward.¹

Follow your kit’s checks:

Malone: confirm the straps are tight, the front and rear tie-downs are tight and the kayak is firmly secured; recheck after 5 miles (8 kilometers).¹
EasyTop: check and retighten loaded straps before departure. Recheck after 30 miles (48 kilometers) or 30 minutes following installation or loading, regularly on longer journeys or rough terrain, and after leaving the vehicle unattended.³
NRS: check strap tension frequently.²
Wilderness Systems: stop shortly after starting; periodically check straps for stretching when wet.⁸

EasyTop loads change steering, braking and sensitivity to side winds. Adjust speed for load, road, traffic and wind conditions, within legal limits. Yakima’s conditional recommendation where no speed limit exists is a maximum 80 miles per hour (130 kilometers per hour); it is not a safe-speed guarantee. Yakima discourages off-road driving.³

Keep EasyTop instructions with the vehicle manual. Inspect for damage, replace worn or missing parts with original parts, and avoid modifications. Clean with water and standard car-wash liquid without alcohol, bleach or ammonium additives, especially in winter.³

Wilderness Systems advises against leaving a boat strapped on a parked car for long periods; heat worsens distortion. If threatening weather permits transport under your kit’s rules, its guidance favors upside-down placement where possible, or a cockpit cover—a fitted cover over the boat’s seating opening—to keep water out. This does not override EasyTop’s rain prohibition.⁸³
