The SeaBoater is always focused on setting new standards and solutions for real cruising yachts.
Over the past ten years, people from our team have focused their efforts on designing custom yacht concepts.
Along with custom yacht concepts, we want to offer through the SeaBoater brand our own vision of yacht development. We would like to describe some methods of our cost-effective carbon yacht building processes.
One of the most well known factors of the SeaBoater way is the cost-effective pricing of the final product, besides the ecological aspects. This cost-effectiveness and an extraordinary price-performance ratio are our main leads through the existing and latest available yacht building technologies.
SeaBoater Yacht Hull Building Technologies
The SeaBoater is a shipyard that builds semi-custom or custom yachts, and our superior fiberglass hulls are not the typical "serialized" fiberglass hulls built by other shipyards that have yacht models available on the market.
The superiority of fiberglass over aluminum and steel hulls is demonstrated with our specialized SeaBoater hull building. SeaBoater uses a special composite fiberglass hull structure, building it with a combination composite of multi-axial and uni-directional fibers. Building it in this way with fiberglass for the yacht hulls makes it close to steel in strength, but it is much lighter than a comparable steel vessel. Additionally, SeaBoater uses one of the great advantages of GRP, which is that the thickness and strengthening can be concentrated exactly where it is required by locally increasing the thickness in specific areas, something that cannot be easily done with steel. Fiberglass hulls built in this way can absorb the highest impact by cushioning loadings on the hull structure, so the advantage of steel in strength is effectively neutralized. As we see it, using pure fiberglass material combined with our specialized way of hull building creates a superior product, making our fiberglass yacht hulls even stronger than other hulls of aluminum and steel.
However, we are aware of all uses for additional carbon hull reinforcements too.
Pure carbon fiber yacht construction is technically not a problem for our shipyard, but this technology is still extremely costly. The SeaBoater has its own way of yacht building, following classic fiberglass and epoxy resin technology, but with additional carbon hull reinforcement solutions.
One or both solutions below depend on the models and the specific requirements of the client.
We are mostly using these additional carbon hull reinforcement solutions:
1. Carbon Fiber Taped Reinforced Hull Areas
Carbon Fiber Tape is used to improve tensile, compressive strength and stiffness in one direction, while adding minimum thickness and weight. Reinforcing tape with fiber bundles held in place by an epoxy filled thread is used for easy handling and wet out. This is not a costly solution, but makes a great additional fiberglass reinforcement of the hull areas on all “connection” places and other required locations. The whole hull of the SeaBoater 78.7 Kiteboat is reinforced in this way with Carbon Fiber Tape.
2. Carbon Nanotube (CNT) technologies
Carbon Nanotube (CNT) technologies improve the properties of fiberglass composite yacht-building materials.
Carbon Nanotubes are eco-friendly, anti-fouling, thermal protected and mechanical reinforcements. And on top of it all, they are very cost effective, so that the boat will not have the high hull building costs as associated with pure carbon hull production. It is pretty clear that the hull will not have the lightness of pure carbon boats, but we have taken cost effectiveness one step further by making a stronger fiberglass hull that can be compared with metal boats and is a lot lighter than metal boats. This is our favorite yacht hull building technology.
Carbon nano-composite materials offer top-quality effectiveness even above conventional composites, and together with aluminum and steel, they make a superior product, and you can see the statistics below.
Higher impact resistance compared to conventional composites as shown below:
+50% Flexural Modulus
+42% Glc Strain Energy Release
+28% Compression Strength
+20% Tensile Strength
+18% Tensile Modulus
+18% Flexural Strength
+17% Compression Modulus
+66% lighter than aluminum
8x stronger than aluminum
+25% greater Shear Strength than Welding
(Repairs are simple as fiberglass, but with the advantage of up to a 25% greater shear strength than welding.)
