Top Marine manufactures heavy duty floating pontoons for boat marinas, yacht harbours, floating platforms and demanding harbour projects. We design them for locations protected by natural landforms or breakwaters, where the permitted wave height is up to 0.5 m.
You can plan different pontoon layouts in our web application and see the estimated cost of the project. In addition, the user manual is available here.
If you work in marina design, harbour engineering or architecture, you can download heavy duty pontoon models and other Top Marine product models from the ProdLib catalogue. You can also read the user manual here.
Heavy duty pontoons for marinas and floating platforms
Heavy duty pontoons provide high stability and strong load-bearing capacity. Therefore, they also work well as floating breakwaters, floating platforms and bases for water-based structures.
For example, you can build a shelter, a floating house or a floating sauna on top of a heavy duty pontoon when the structure, anchoring and local conditions are suitable.
Heavy duty pontoons come in three standard widths: 2.4 m, 3 m and 4 m. The standard lengths are 9 m, 12 m, 15 m, 18 m and 20 m. The freeboard height is 0.49–0.7 m.
We deliver the concrete surface with a dry-brushed finish as standard. However, you can add timber decking as an accessory. We make the decking from high-quality impregnated knot-free timber.
For mooring, you can equip the pontoon with boat booms with plastic floats, mooring fingers, mooring buoys, mooring rings or bollards.
Accessories for heavy duty pontoons
We offer a wide range of accessories for heavy duty pontoons. These include timber decking, side decking, railings, swimming ladders, fenders, bollards and mooring rings, lighting posts and lifebuoy sets.
In addition, you can choose premium timber decking and LED-lit bollards for projects where a more exclusive look is required. For more ideas, read the article Accessories to make your pontoon feel homey – 6 products to consider installing.
Maintenance of heavy duty pontoons
Heavy duty pontoons require little maintenance. However, we recommend checking and cleaning the pontoon before the new season in spring and after the end of the boating season in autumn.
To ensure a long service life, we recommend the following steps:
- clean the concrete surface with a pressure washer once a year;
- wash timber decking with a brush or pressure washer and treat it once a year with a wood preservative that protects against UV radiation;
- regularly check chain fastenings, fasteners and hinge connections;
- remove ladders and boat booms in autumn to avoid ice damage.
You can find more detailed instructions in our pontoon maintenance guide.
