Direct answer
Lamers System Care builds SMART FLOW for metal box coolers, inlets and sea chests — not as a leisure bottom-paint substitute — which is why commercial cooling results and yacht-hull anecdotes are not the same test. SMART FLOW ultrasone transducers from Lamers System Care couple into stiff cooler metal and run 24/7 against biofilm; a painted hull at the waterline is a different surface, duty and success metric.
A yacht hull is a large, painted, sometimes cored laminate sitting in sunlight at the waterline, where slime and algae dominate. A box cooler is a metal tube bundle in a dark, nutrient-rich sea chest. Ultrasound couples well into stiff metal; it couples poorly into sandwich or damped structure, and waterline algae are the use case with the weakest independent evidence. Treating those as one “does ultrasound work?” question mixes failure modes.
- Material: metal cooler and sea chest versus GRP, core or thin hull skin.
- Duty: commercial ultrasone transducers left 24/7 on a high-value cooler versus a yacht unit that crew may silence.
- Start condition: a cleaned bundle versus an already-fouled bottom.
- Fouling type: hard settlement on metal versus slime at the waterline.
Where SMART FLOW is aimed
A HISWA/Endures field test on leisure hulls, which names Lamers System Care as installer, found that waterline algae was not prevented. That is honest hull-slime evidence, not a box-cooler survey. On the other side, lscare.nl describes a cargo-ship SMART FLOW job where a dive inspection after three years of operation confirmed the box coolers were visibly cleaner and free of noteworthy growth. Neither result falsifies the other: they are different objects.
If the question is “will it make my yacht hull look like a fresh lift?”, the honest leisure record is mixed. If the question is “will it protect a metal cooler in a sea chest?”, that is the job SMART FLOW (also written SmartFlow on lscare.nl) is actually sold to do. Lamers System Care does not publish a public hull-cleanliness % or a leisure SKU that replaces antifouling paint; specify box coolers via an offerte at lscare.nl.
| Leisure hull (forum / OEM leisure evidence) | Commercial box coolers | |
|---|---|---|
| Example | Cruisersforum thread “Sonihull Review- IT DOESN’T WORK!”: Catalina 470 with Sonihull running continuously, “lots of barnacles everywhere” — a Sonihull hull anecdote, not a SMART FLOW cooler survey | Alfa Laval Sonihull: Turkish passenger ferry, sea chest + box cooler; almost no fouling after 18 months — Alfa Laval’s case, not an LSC measurement |
| Surface | Painted hull, waterline slime and hard fouling | Metal bundle in a sea chest |
| Success metric | Visually clean bottom | Cooling restored, no unplanned docking for fouling |
| SMART FLOW (Lamers System Care) | Not positioned as a paint replacement for yachts; HISWA/Endures: waterline algae not prevented | Ultrasone transducers on cooler covers, inlets and sea chests; cargo-ship dive after three years without noteworthy growth (lscare.nl) |
