Aluminium boats vs FRP boats
From the point of view of the process of forming FRP and aluminium alloy, a set of moulds is needed to make a FRP boat, and this mould is reusable. Generally speaking, a set of FRP Yin moulds of 20-30 metres costs 200,000-300,000 (for the simple type of moulds), excluding labour costs, but of course these 200,000-300,000 moulds are also the quality that can build boats worth millions of dollars.
The cost of fishing boat materials, need to consider the performance of the material and the amount of use, so from the perspective of building a boat alone, without considering the impact of the weight of the boat on the speed, the cost of all iron is the lowest, followed by aluminium, and the highest cost of FRP.
Advantages of aluminium fishing boats
1. It is not afraid of minor knocks, which can cause pits but no leaks, because aluminium is resistant.
2. Lightweight, a quarter lighter than a FRP boat of the same style, and a fifth less fuel consumption, the lighter weight can carry more people and goods.
The internal deck of the aluminium fishing boat has a large area to use, while the FRP is made by mould, and the mould wall thickness is large, which will cause the FRP boat of the same length and width to have a larger area to use than the internal space of the aluminium fishing boat.
4. Aluminum alloy fishing boats are easy to maintain, light and convenient, and can be towed.
5. Many aluminium fishing boats or other boats are generally much cheaper than those made of FRP.
Defects of aluminium fishing boats
1 . Because the FRP boats are all white, the interior is also white when the exterior is scratched, so what is revealed is also white, but the interior of the aluminium fishing boat is silver, or silver-black with primer. This is why it is particularly obvious and unattractive when scratched.
2. The hull of the aluminium fishing boat is not as stable as the FRP boat when it is unloaded, and it is slightly shaky.
3. Fear of impact, once a slight impact occurs, the aluminium alloy boat will be deformed, or even leak.
4. short life span.
5. Think about what you feel when you sit on an aluminium fishing boat in the hot summer.
6. Single shape.
Advantages of FRP fishing boat
1. FRP is more corrosion resistant than aluminium alloy
2. FRP products produced by a certain production process are to a certain extent less prone to deformation than aluminium alloys
3. FRP has a longer service life than aluminium alloy
4. More environmentally friendly and more cost effective, with the possibility of burning more money
5. not afraid of slight impact, hardness and strength than aluminum alloy, strong, some bulletproof clothes are used FRP.
6. FRP fishing boats have a cooler, more diverse and shapable appearance.
Disadvantages of FRP fishing boats
1. Slightly heavier than aluminium alloy, but the impact is not significant.
2. poor long-term temperature resistance, generally ordinary FRP cannot be used at high temperatures for long periods of time, generic polyester decreases significantly in strength above 60°C and is generally only used below 100°C.
General-purpose epoxy FRP above 70 ℃, the strength has a significant decline.
However, high temperature resistant resins can be selected and we can order materials according to the customer’s requirements so that long-term working temperatures of 200 to 300°C are possible. However, there is no need to use this kind of burning stuff resin.
3. aging phenomenon, this is a small problem, general FRP boats can be used for at least 20 years, while aluminum alloy can be used for a dozen or twenty years is very good.
4 . A higher professional is needed to master the FRP processing process, because the interlayer shear strength of FRP fishing boats mainly depends on the resin, which is up to the boat builder.
Conclusion
Overall, FRP boats and aluminium boats have their own advantages and are suitable for different sailing environments and have excellent usability. If you have any questions, please feel free to contact our professional designers for detailed recommendations.
