Collarcraft — RIB & boat collars

Collars built to survive impact.

One roof. Design to delivery.

We design and manufacture inflatable collars for rigid inflatable boats — commercial, defence, and leisure hulls. Every collar is specified to the hull, not pulled from a catalogue.

Materials, seam method, and chamber layout are decided before the first cut. Nothing is off-the-shelf.
