Dutch maker Olivier van Embden successfully designed, constructed, and demonstrated a rigid kayak weighing only 4.0 kilograms (8.82 pounds). Built primarily from cardboard and epoxy, the 4.3-metre vessel was independently verified for weight and subsequently demonstrated floating while carrying a human occupant, establishing a new benchmark for lightweight kayak construction.
Transparent Adjudicator's Statement
Summary of Claim
The claimant sought recognition for constructing the world's lightest rigid kayak. The project centered on the use of unconventional materials—specifically cardboard reinforced and waterproofed with epoxy—to create a vessel that would remain structurally rigid, capable of flotation, and able to support a human occupant while weighing less than 5 kilograms.
The claimant stated that the project originated from an interest in unconventional boatbuilding and lightweight structural design. Following construction, the completed kayak was independently weighed in the Netherlands and publicly demonstrated on a canal in Utrecht.
Evidence Submitted
• Independent weight-verification documentation from a certified measuring organization in the Netherlands
• Video evidence documenting the weighing process and confirming a final verified weight of 4.0 kilograms
• Video evidence demonstrating that the kayak could be carried by a single individual
• Video evidence showing successful flotation and operation on water with a human occupant aboard
• Public flotation-test video:

• Photographic documentation of the completed kayak
• Dimensional specifications confirming an overall vessel length of 4.3 metres
• Written construction documentation describing materials, methods, and design adaptations
• Project build archive:

• Narrative testimony provided by the claimant regarding the project's development and testing process
Comparative and Cross-Archive Benchmark Review
Atlas researchers conducted a comparative review of publicly available records, archives, engineering projects, maker communities, media reports, academic references, and publicly accessible databases maintained by major world record organizations.
The review identified numerous lightweight kayak and ultralight watercraft projects, including a widely cited graphene-reinforced composite surfski weighing approximately 9.3 kilograms (20.5 pounds), which has been publicly described as the world's lightest kayak in industry publications. Researchers also identified references suggesting prior recognition of lightweight canoe or kayak prototype categories; however, no publicly available certified benchmark was located that matched or exceeded the claimant's verified achievement under a substantially similar definition of a rigid kayak.
At the time of adjudication, the strongest publicly documented benchmark identified during Atlas research was approximately 9.3 kilograms. Olivier van Embden's verified kayak weight of 4.0 kilograms represents an improvement of approximately 57 percent over that benchmark.
Verification Methodology
Atlas World Records evaluated the submission under four primary criteria:
Weight Verification
The vessel's weight was independently measured and documented through certified weighing procedures and supporting video evidence.Rigid Construction
The kayak was reviewed to confirm that it constituted a rigid, self-supporting watercraft rather than an inflatable, folding, or collapsible vessel.Human-Carrying Capability
Evidence was reviewed demonstrating that the kayak was capable of safely supporting a human occupant.Flotation
Video documentation was reviewed to confirm that the kayak successfully floated on water while carrying a person.
All submitted evidence was examined for continuity, consistency, credibility, and alignment with the record definition.
Adjudication Findings
Atlas determined that the claimant successfully constructed a rigid kayak measuring 4.3 metres in length and weighing 4.0 kilograms.
The submitted evidence demonstrated that the vessel was capable of floating on water while supporting a human occupant and therefore satisfied the requirements established for this category.
The construction materials, consisting primarily of cardboard reinforced with epoxy, were found to be consistent with the claim and represented a highly unconventional approach to lightweight watercraft design.
No conflicting publicly documented benchmark was identified during the comparative review process.
Conclusion
Following review of the submitted evidence and completion of Atlas verification procedures, Atlas World Records recognizes Olivier van Embden as the holder of the world record for the Lightest Rigid Kayak.
The verified record measurement is 4.0 kilograms (8.82 pounds) for a rigid kayak measuring 4.3 metres in length and constructed primarily from cardboard and epoxy.
