Solid Foam Boat Collar Systems for Workboats and Patrol Craft
A foam boat collar is hull-attached fendering: a solid closed-cell foam core under a sprayed polyurea (SPUA) skin, with no air chamber to inflate, monitor or lose. JettyGuard engineers each collar around one hull — one section profile, one total run, one fixing interface — and manufactures it to that specification.
Inside the collar: solid foam, not contained air
01
Closed-cell foam core. Carries the collar's form and volume. Load goes into the foam body, so the section holds its shape without internal pressure.
02
Reinforcement where the design requires it. An engineered element applied where the specification calls for it, not a standard fitted to every section.
03
Sprayed polyurea (SPUA) skin. The wearing surface that takes abrasion and contact. Finish and colour are set by the project specification.
04
No inflatable chamber. No valve, no inflation pressure to maintain and no pressure check before the vessel goes to work. The skin can be damaged; it cannot deflate.

Four decisions define the product
What you configure, and what each choice changes
There is no catalogue size to select. New builds can coordinate the collar with the hull; retrofits must be engineered around the hull as built.
Engineering and production scope
Who engineers it, who builds it, what gets checked
Geometry and interface questions are resolved before a price exists.
Every collar enquiry is reviewed against the supplied hull and section data so the delivered section is defined against the vessel, not a generic catalogue size.
| Evidence area | What is in scope |
|---|---|
| Manufacturing scope | JettyGuard manufactures foam-core, reinforced-layer and SPUA-coated fendering products. Foam raw material is purchased; cutting, shaping, reinforcement, coating and assembly are our own work. |
| Certification and inspection | Our manufacturing facility is certified to ISO 9001:2015 and ISO 14001:2015. JettyGuard's own ISO 9001:2015 certification is in progress. BV or SGS inspection is available on request. |
| Documentation | Inspection stages, records and witness points are agreed in the quotation. State specific procurement documentation at enquiry so it is in scope from the start. |
What to send, and what happens next
A section drawing and a total run are enough to start. Four compact groups move the enquiry toward a quotation.
01
Vessel and project
Vessel type and length; new build or retrofit.
02
Section and coverage
Section profile and dimensions in millimetres; total run and its split across bow, sides and transom.
03
Segmentation and interface
Handling or transport length limits; hull structure at the collar line and fixing intent.
04
Skin, context and programme
Outer-skin and reinforcement requirement; operating context, quantity and programme dates.
Frequently asked questions
Can you quote from a total length alone?
It is a valid starting point but not a quotation basis. Two quotations for 60 metres of foam collar can describe completely different products, so the cross-section, segmentation, fixing intent and skin requirement have to be settled first. Send what you have and the review will come back with the specific gaps.
Is a solid foam collar the same as an inflatable boat collar?
No. A solid foam collar carries load in a closed-cell foam body under an SPUA skin, with no air chamber, no valve and no inflation pressure to maintain. An inflatable collar relies on a pressurised chamber. Hybrid systems combine both, and their chamber layouts differ between builders.
Can a solid foam collar be retrofitted to an existing hull?
Retrofit is a normal route, but suitability is assessed hull by hull rather than assumed. It needs measured section drawings or a template of the as-built profile, plus the structural detail at the collar line. We do not claim universal retrofit compatibility or a single standard fixing method.
