We have produced polyethylene spar buoys in Finland since 1976. Even today 30.000 units of SeaHow polyethylene buoys of different type are in use all year round, including winter time. The annual production of our factory exceeds 1.500 units. The buoys meet the IALA recommendations.

Polyethylene spar buoys have unique technical features that provide significant advantages over conventional steel buoys. Over the years they simply come cheaper since, because:

• Light weight and anchoring
• Lighter deployment equipment
• Less maintenance and costs
• Guaranteed lifetime 20+ years
• Easy to customize
