.Newly built stable pontoons for custom houseboats. The best sustainable materials are used. The insulated subfloor is 10cm thick and maintenance-free. The pontoons are built on request in Friesland, ranging from 6 to 15m in length and width according to your wishes! All of this within a short delivery time. The floats are made of super strong HDPE material, which means no antifouling and anodes are needed. The floats are unsinkable and are filled with non-water-absorbing hard foam blocks of 12 cm thick. These blocks have a closed cell structure and are resistant to rot. The top is then welded shut again. This creates a very strong sandwich construction. The floats are drilled to keep the pressure inside and outside the same in any weather condition. This makes the floats fireproof. The freeboard of the floats is approximately 10 cm. The floats, which are 8 mm thick, are maintenance-free and stay clean, as little growth adheres to them. The wide unsinkable floats are fully foamed and can carry a weight of 7 tons. The draft will then be 40 cm. With a weight of 9 tons excluding the weight of the pontoon, the draft is 50 cm. The weight of the pontoon measuring 8 by 4 is approximately 1800 kg. UV rays have no effect on the material. There is space at the back of about 1 meter wide for placing a motor support for an outboard motor. A bow can also be mounted for better sailing characteristics. Deliveries of up to 3.5 m wide are also possible. Then the transport costs are cheaper because it is not special transport.
