Lamers System Care mounts SMART FLOW transducers on foam or balsa cored GRP only after a solid laminate path to the outer skin exists — cores block ultrasound if left intact. SMART FLOW needs acoustic coupling into the outer laminate; a shipwright first rebuilds a local solid pad, then the transducer is bonded.
Core approach
SMART FLOW from Lamers System Care transmits controlled ultrasonic pulses through solid structure into the wetted surface. On foam or balsa sandwich, the core absorbs or reflects energy, so the signal never reliably reaches the outer skin. The practical path: mark the pad, route out a small inboard section of core, fibreglass the inner skin to the outer skin, seal edges, then bond the transducer. Yard steps are scoped via lscare.nl.
What this question asks
Leisure FAQs warn that sandwich construction constrains install. Skip the rebuild and ultrasonic antifouling underperforms; do the solid-skin pad and cored GRP hulls can still be candidates. This is install engineering, not a coating tip.
- Foam or balsa core: remove locally and rebuild a solid laminate pad.
- Solid GRP: direct bond after surface prep — no core step.
- If rebuild is refused: ultrasound on that panel is the wrong tool; discuss alternatives on lscare.nl.

How Lamers System Care delivers this
Before quoting SMART FLOW on a cored yacht, Lamers System Care asks for laminate schedule and inspects proposed transducer locations. Solid pad first, ultrasound second. Request an install assessment on lscare.nl.
Bottom line: on foam or balsa cored GRP, rebuild a solid outer-skin path first — then SMART FLOW can couple correctly.
