CATAMARANS FOR RAFTS

Plastic catamarans for rafts are durable and resistant to all weather conditions

A catamaran is a type of boat consisting of two parallel hulls.
Designing a catamaran is a demanding task, as the catamaran must withstand the resistance or load that will arise from the use or exploitation of the boat.

The same rules apply to designing a catamaran as for boats with a single hull, with the primary difference being the catamaran’s transverse stability.

The materials our catamarans for rafts are made from are:

Environmentally tested (do not pollute the environment) and made from HDPE,
Guarantee waterproofing and a long-lasting solution, as the material loses only 5% of its properties after 50 years of use,
Resistant to UV rays, withstand extreme temperatures from -30°C to +80°C,
Resistant to saltwater,
Have good buoyancy,
Resistant to impacts, meaning no visible marks are left on them,
Stable for navigation and stand out from the competition with a beautiful design line,
And importantly, they are easy to assemble and have minimal maintenance costs.

Čabar Plast pontoons made from HDPE are manufactured in standard diameters:

Ø 500 mm
Ø 600 mm
Ø 800 mm
Ø 1000 mm
Ø 1200 mm
Ø 1300 mm
Ø 1600 mm

How to Calculate the Buoyancy of a Catamaran, Raft, or Any Floating Object?

First, we need to know the buoyancy of the pontoons. Čabar Plast pontoons with an internal diameter of 60 cm have a buoyancy of 140 kg per linear meter, meaning, for example, a pontoon of 6 m in length has a buoyancy of 6×140=840 kg.

A pontoon with an internal diameter of 80 cm has a buoyancy of 230 kg per linear meter, meaning a pontoon of 6 m in length has a buoyancy of 6×230=1380 kg.

Čabar Plast pontoons are designed so that at maximum load of the catamaran or any other floating object, the pontoon is submerged halfway into the water. Therefore, it is necessary to know the total mass of the raft, catamaran, or other floating object when it is fully loaded, which means adding up the masses of the steel structure, timber, cabin, other cargo, and the maximum number of people who will be on the raft at one time.

Čabar Plast pontoons are easy to transport, install, and can carry heavy loads.

A catamaran that consists of three instead of two hulls is called a trimaran, which consists of one central hull and two outer hulls.

Our company, with years of experience monitoring market changes and the demands of our consumers, produces the most modern catamarans, trimarans, rafts, pontoons at the most favorable prices, all to meet the needs of our clients.

Who Buys a Catamaran?

Purchasing a catamaran is a decision for those seeking adventure and wanting to connect with the sea in a unique way. Catamarans are popular among sailing enthusiasts and water sports lovers, offering stability, spaciousness, and comfort on the open sea. Those who buy catamarans are usually experienced sailors who appreciate the elegance and efficiency of sailing, but also families looking for a safe and fun vessel for holiday relaxation on the water.

People who buy catamarans want to experience the sailor’s life. Mainly, catamarans are used for sailing and recreational purposes. Sailing or cruising on a catamaran represents a form of enjoyment for all water lovers.

What is the Difference Between a Catamaran and a Boat?

The difference between a catamaran and a traditional boat lies in their structure. While a boat has one hull and relies on a deeper draft for stability, a catamaran relies on two parallel hulls that provide greater stability and a shallower draft. This twin-hull solution allows catamarans to sail faster and offer less resistance when cruising, making them ideal for those seeking speed and efficiency.

A trimaran, as an extended version of a catamaran, has one main hull and two smaller side hulls, providing even greater stability and space. Trimarans are especially valued among sailors seeking top performance and comfort during longer sea voyages.

Can a Catamaran Sink? Can Sailing Catamarans Sink?

While there is a fear that a catamaran can sink, the advanced technology and design used in the construction of modern catamarans minimizes this possibility to a minimum. Critical elements contributing to the safety of a catamaran include waterproof bulkheads, foam filling, and sandwich construction that provides additional buoyancy.

These elements, together with the multiple hulls, ensure that the catamaran remains afloat even in the most challenging conditions, making it a reliable choice for sailors seeking safety and stability at sea.

What Can the Bow of a Catamaran Look Like?

The bow of a catamaran, also known as the prow, can be designed in several ways depending on specific needs and aesthetic preferences. Some common designs of a catamaran bow include:

Flat bow – This is the simplest design, where the bow of the catamaran ends with a flat horizontal line. This design is practical and often used for commercial catamarans.
Slightly recessed bows – This design features a slightly sloped or recessed line at the top of the hulls, which can improve aerodynamics and reduce resistance while sailing.
Sharply sloped bows – In this design, the tops of the hulls are significantly sloped, giving the catamaran an aggressive appearance and can further enhance water performance.
Bows with a point – This design includes a pronounced point at the top of the hull, giving the catamaran a classic sailboat look and can help in cutting through waves.
Bows with a point and fins – This sophisticated design involves a combination of a point and additional fins or winglets at the tops of the hulls, increasing the catamaran’s stability and maneuverability.

Regarding color, catamarans are not limited to just black. There are various colors and painting schemes that can be applied to catamarans, including white, blue, green.

The choice of color often depends on the personal preferences of the owner, the purpose of the vessel (recreational use, racing, commercial use), and the aesthetic expression they wish to achieve.
