What is Cruiser 250 and why choose it
Cruiser 250 from International Náutica is a multi-purpose polishing antifouling coating, effective against fouling organisms such as slime, aquatic plants and animals. It is suitable for consumer application on sailing and power boats operating in both fresh and salt water and is designed to provide up to one year of protection when correctly applied. Thanks to its polishing (self-polishing) technology, it helps maintain a smooth underwater hull surface while controlling fouling throughout the season.
Main features

- Polishing antifouling: Antifouling film polishes in service, helping to maintain performance over the season.
- Fresh and salt water use: Suitable for vessels operating in rivers, lakes, estuaries and coastal waters.
- Up to 12 months protection: Designed to give up to one year protection for both sailing and power boats when the specified film thickness is achieved.
- Consumer-applied: Can be applied by brush or roller, without specialist spray equipment.
- Wide colour range: Available in Dover White (YBP150), Red (YBP151), Blue (YBP152), Navy (YBP153) and Black (YBP154).
- Matt finish: Underwater hull dries to a matt appearance; true colour develops after immersion.
- Versatile substrates: Suitable for GRP, wood, steel/iron and lead when correctly primed.
- Coverage guidance: Practical coverage of approximately 9 m²/L per coat by brush/roller.
- Biocidal antifouling: Contains biocides; handle and dispose of responsibly.

Applications and use cases
Recommended applications
- Hull antifouling for GRP sailing yachts operating in coastal waters or inland waterways.
- Underwater protection for motor boats and power craft, subject to regular immersion.
- Antifouling for steel or wooden hulls when correctly primed with compatible International primers.
- Lead keels and appendages primed with Interprotect or Primocon.
Surface preparation
- Previously painted surfaces in good condition:
- Remove all fouling, contamination and the leached layer.
- Wash with high-pressure fresh water (approx. 3000 psi / 207 bar).
- Scrape and wet sand with 80–120 grade abrasive paper.
- Do not dry sand.
- If the existing antifouling is incompatible or unknown, seal with a suitable International barrier/sealer coat.
- Previously painted surfaces in poor condition:
- Remove all traces of old antifouling with Interstrip.
- Bare substrates (priming overview):
- GRP: Prime with Gelshield 200 for osmosis protection, or Primocon or Interprotect.
- Steel/iron/lead/wood: Prime with Interprotect or Primocon.
- Plywood: Prime with Epiglass followed by Interprotect.
- Full details of bare substrate preparation are provided in the respective primer datasheets.
Application conditions and tips
- Mixing: Stir thoroughly until a completely uniform consistency is obtained before use.
- Thinning: Not recommended; thinning may compromise antifouling performance if the correct dry film thickness is not achieved.
- Cleaner: YTA085 International Antifouling Thinner No. 3.

- Substrate temperature: at least 3°C (5°F) above dew point and below 35°C (95°F).
- Sanding: Antifoulings should only be wet sanded. Never dry sand or burn off old antifouling.
- High-speed craft: Regular operation at high speed (around 30 knots or more) may lead to earlier wear; suitability should be checked with an International Paint representative.
FAQ
1. How long does Cruiser 250 protect my boat?
Cruiser 250 is designed to provide up to one year of antifouling protection for sailing and power boats when applied at the recommended 2 coats (total 120 microns dry film thickness) and used under typical conditions.
2. Can I use Cruiser 250 on an aluminium hull?
No. Cruiser 250 is not suitable for aluminium or alloy substrates, nor for zinc-sprayed surfaces.
3. Which substrates is Cruiser 250 suitable for?
It is suitable for GRP, wood, steel/iron and lead, provided they are correctly prepared and primed with compatible International primers.
4. Can I apply Cruiser 250 over an existing antifouling?
Yes, it can be applied directly over most types of existing antifoulings that are in sound condition, except VC17m and PTFE-based antifoulings. If compatibility is uncertain, a suitable International barrier/sealer coat should be used.
5. How many coats do I need?
The manufacturer recommends 2 full coats of 60 microns dry film thickness each (total 120 microns) for approximately 12 months protection, plus an extra stripe coat on high-wear areas.
6. What is the recommended coverage per litre?
The theoretical coverage is about 10 m²/L per coat by brush or roller. A practical coverage of around 9 m²/L per coat is typically used as a guide.
7. Can I spray apply Cruiser 250?
The application methods given for Cruiser 250 are brush and roller. Consultar ficha técnica del fabricante.
8. How soon after painting can I launch the boat?
Minimum immersion time depends on temperature: approximately 8 hours at 5°C, 6 hours at 15°C, and 4 hours at 23–35°C.
9. What happens if I delay launching after painting?
Within 5–35°C, maximum immersion time is indicated as up to 6 months between application and immersion.
10. Does the dry colour match the final underwater colour?
The true colour develops after immersion; the shade when dry may differ from the in-service colour.

Section 8 – Individual protection measures
Cruiser 250 is classified as a flammable liquid and vapor, harmful if swallowed, causing serious eye damage, potentially causing an allergic skin reaction and very toxic to aquatic life with long lasting effects. Appropriate personal protective equipment (PPE) and safe handling practices are essential.
Exposure controls and personal protection
- General hygiene: Wash hands, forearms and face thoroughly after handling and before eating, drinking or smoking. Contaminated work clothing should not leave the workplace and should be washed before reuse. Ensure eyewash stations and safety showers are available close to the work area.
- Eye and face protection: Use chemical splash goggles and/or a face shield conforming to an approved standard whenever there is a risk of liquid splashes or spray reaching the eyes. If inhalation hazards exist, a full-face respirator may be required instead.
- Hand protection: Wear chemical-resistant, impervious gloves complying with EN374 or equivalent.
- For prolonged or frequently repeated contact: protection class 6 (breakthrough time greater than 480 minutes); recommended materials include Viton or nitrile with a minimum thickness of 0.38 mm.
- For brief contact: protection class 2 or higher (breakthrough time greater than 30 minutes); recommended nitrile gloves with minimum thickness of 0.12 mm.
- Gloves should be inspected regularly and replaced if damaged or degraded.
- Skin and body protection: Wear suitable protective clothing selected according to the task and risk assessment. Where there is a risk of ignition from static electricity, use anti-static protective clothing, including overalls, boots and gloves that comply with EN 1149 or equivalent.
- Respiratory protection: When ventilation is inadequate or during operations such as sanding where inhalation exposure may occur, use a respirator conforming to EN140 fitted with an A/P2 filter or better, as part of a properly implemented respiratory protection program.
- Engineering controls: Use only with adequate ventilation. Provide local exhaust or process enclosure to keep airborne concentrations below any recommended limits and below the lower explosive limit. Use explosion-proof ventilation equipment.
- Environmental controls: Emissions from ventilation or process equipment should comply with environmental legislation. Additional treatment such as fume scrubbers or filters may be required to reduce emissions.
- Sanding guidance: Antifoulings should only be wet sanded. Dry sanding or burning off old antifouling must be avoided to reduce dust and hazardous fume generation.
