Hull fouling has been solved. Most fleets haven't been told yet.
The maritime industry has been managing fouling with a technology that degrades, depletes and expires — not because it works best, but because the alternative hadn't been proven at scale.
SEA-SPEED V 10 X ULTRA — hard-film Silane-Siloxane, zero biocides, 10-year warranted system. Lloyd's Register certified. In service on 400+ naval and commercial vessels worldwide.
Three things the industry assumes are fixed. They're not.
Sea-Speed doesn't improve conventional antifouling — it replaces the logic behind it.
"Biocides are a necessary part of hull protection."
Sea-Speed releases fouling through surface chemistry alone. No TBT. No copper. No zinc. Zero.
"Hull performance degrades between drydocks — that's unavoidable."
Unlimited underwater grooming restores the surface — every time, without film loss or toxic release.
"Recoating every 3–5 years is a fixed cost of operating a vessel."
One application. Ten-year warranty. One set of costs for an entire decade.
A different class of coating.
SEA-SPEED V 10 X ULTRA is the only hard-film Silane-Siloxane foul release coating available today. Not an improvement on antifouling — a fundamentally different answer to hull fouling.
- <20µ average Rz — nano-smooth, glass-hard finish that holds its smoothness in service
- Non-depleting, non-ablative — coating is never consumed; thickness preserved over 10 years
- 1,000+ underwater cleans — without film loss or toxic release; performance maintained
- Barnacles wipe off by hand — after 18 weeks static immersion; ultra-low fouling adhesion
- Zero biocides — no TBT, copper or zinc; compliant in all trading areas worldwide
- 95% solids by volume — minimal VOC; safe for applicators and yard workers
- Pencil hardness 6H — extremely hard yet flexible; no cracking or delamination
The numbers behind the decision.
Hull coating is a capital allocation decision. The 10-year model covers coating cost, fuel savings, reduced drydock frequency and CO₂ reduction.

Proof from the people who run the vessels.
We are seeing 2–3% decrease in consumption at 21 knots and a 5–7% improvement at 15–17 knots. This equates to a 17% improvement in our Carbon Intensity Index between 2021 and 2022.Joey HalversonDirector of Ship Management, TOTE Services LLC — December 2022
Sea-Speed V 10 X ULTRA exceeds environmental regulations globally for all types of vessels. The technology is highly advanced from both a technical and functional viewpoint. It has a phenomenal future in the maritime industry.Graham PerkinsTechnical Marine Consultant — former Senior Technical Project Manager, INCAT
