FAQ
Frequently asked questions
Find answers to the most important questions about modular floating docks and marine solutions.
What is a modular floating dry dock?
A modular floating dock is constructed from interconnected floating elements made of HDPE plastic. The system is flexible, allowing you to customize the shape and size for a jet ski, boat, bridge, or even an entire marina — and expand it later.
Can a floating dock withstand Nordic winter conditions?
Yes. Our systems are dimensioned for Scandinavian wave, frost, and ice conditions. The materials are UV and salt resistant and do not require maintenance such as painting or impregnation.
How long do delivery and installation take?
Standard solutions are typically delivered within a few weeks. Larger marina projects are individually planned — contact us for a timeline for your specific project.
Can I get a non-binding quote?
Yes. Use 'Get a quote' or 'Design your dock', and our advisors will get back to you with a non-binding proposal tailored to your needs and waters.
Do you sell to both private individuals and businesses?
Both. We deliver to private boat owners and jet ski owners, as well as marinas, harbours, municipalities, clubs, and marine contractors.
