The catamaran is a name for one type of ship that consists of two parallel hulls.


The construction of the catamaran is hard work, because the catamaran must respond to the resistance, ie, the burden that will arise from the exploitation of the ship.

When constructing the catamaran, the same rules as for ships that have one hull apply, the basic difference in catamaran is the transverse rigidity.

Katamarani za splavove

The materials from which our catamarans have been built are:

  • Eco tested (non-polluting) PEHD
  • guarantee watertightness and is a long lasting solution, because the material loses 5% of its properties after 50 years of use
  • resistant to UV rays, tolerate extreme temperatures from -30 ° c to + 80 ° c
  • They are resistant to salt water
  • They have good carrying capacity
  • they are resistant to impacts, which means that no visible traces remain on them
  • they are resistant to impacts, which means that no visible traces remain on them
  • and what is very important is easy to mount and have minimal maintenance costs.

Čabar plast pontoons from PEHD are made in standard diameters:

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

Design Čabar Plast pontoon can be different depending on the floating object:

  • peaks can be flat,
  • mildly bent peaks,
  • cuts the tops all the way,
  • peaks only with a spike,
  • tops with spitz and feathers.

Plastic pontoons, no matter what purpose you use them, are ideal as long-lasting, quality, unsinkable and cheaper than any other type of similar purpose.

The base of the catamaran is a pontoon. Čabar plast pontoons can be used without fear of environmental impact because they meet all ecological standards. They are long-lasting, indestructible and unsinkable because they are divided into chambers that can be filled with foamplasts as needed. Their application is multiple and used for various purposes.

How to calculate the capacity of catamarans or any floating object?

First we need to know the load capacity of the pontoon. Čabar plast pontoon inner diameter of 60 cm has a load of 140 kg per meter, which means that for example, A 6 m long pontoon has a load of 6 × 140 = 840 kg. The Ponton inner diameter of 80 cm has a load of 230 kg per meter, which means that the 6 m long pontoon has a load of 6 × 230 = 1380 kg

Čabar plast pontoons are designed to withstand the maximum loading of catamarans or any other floating object, the pontoon being submerged in water up to half. Therefore, it is necessary to know what is the weight of the raft, catamaran or other floating object will be when it is maximally loaded; therefore, we must assemble the masses of steel construction, timber, houses, other cargo and the maximum number of people who will be onboard at one time.
Čabar layer pontoons are easy to transport, easy to install, they can carry heavy loads.

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

Our company with many years of experience following the changes in the market and the demands of our customers manufactures at the most favorable prices of the most up-to-date catamans, trimmings, rafts, pontoons in order to meet the needs of our clients.
