Vacuum Fiberglass RIB Boat Hull

How to choose suitable fiberglass rib boat from China?

Many factors can decide the fiberglass rib boat quality. 

Hull production process: do with vacuum process or not , normally larger size of RIB boat size above 5.8m recommend hull production with vacuum technology. 

Tube production process: according to worker exact working experience

(1). Fiberglass

Fiberglass is an inorganic non-metallic material with excellent performance. It is made of glass balls or waste glass through high-temperature melting, drawing, winding, weaving and other processes. In hull manufacturing, fiberglass has the characteristics of high strength and light weight. Compared with traditional metal materials, it is not easy to rust, can resist the corrosion of seawater, and greatly prolongs the service life of the hull.

For example, in the hull manufacturing of some small yachts, fiberglass can provide sufficient strength to support the hull structure, while keeping the weight of the yacht at a low level, which is conducive to improving the speed and fuel economy of the yacht.

(2). Vacuum forming technology

Vacuum forming is a manufacturing process. When manufacturing a fiberglass hull, the fiberglass material is placed in a mold, 

and then the fiberglass material is tightly fitted to the mold surface by vacuuming. This process can effectively remove air and reduce the generation of bubbles.

For example, when manufacturing a hull with a complex shape, vacuum forming technology can ensure that the fiberglass is evenly distributed in all corners of the mold, 

making the wall thickness of the hull more uniform. The hull structure manufactured in this way is more stable and the strength distribution is more reasonable.

Advantages

(1). Performance advantages

This hull has good hydrodynamic performance. 

Since fiberglass can be made into a streamlined shape through a mold and the surface is relatively smooth, 

it can reduce the resistance of the hull when sailing in the water. This allows the boat to achieve higher speeds or lower fuel consumption under the same power conditions.

For example, racing boats usually use vacuum fiberglass hulls because their good hydrodynamic performance helps to achieve better results in the competition.

(2). Durability and maintainability

As mentioned earlier, fiberglass itself is corrosion-resistant, and the vacuum forming process makes the hull structure tighter. 

In terms of maintenance, compared with wooden hulls, it does not require regular anti-corrosion treatment, such as painting, replacing rotten wood boards, etc. 

It only needs to clean the hull surface regularly and check whether there are any damaged areas for repair.

Some commercial fishing boats use this hull, which can withstand the erosion of seawater and various severe weather conditions 

during long-term offshore operations, and the maintenance cost is relatively low.
