There are several reasons why trampolines are the right choice in catamaran design: It is lightweight, gives little resistance to wind and water, is comfortable, and much more. Read the entire list later in this article.
Different functions of a trampoline
There are different types of catamarans, and the trampoline will have different functions depending on which type of vessel it is mounted on.
On a day cruiser racing type of catamaran, the trampoline is the platform on which you sit on.
On a livable catamaran it is typically only the front of the catamaran, that has a trampoline.
I have never seen a power catamaran with trampoline.
The above video shows a modern type of racing catamaran with foils. This type of day cruiser was invented in the 70ies and mass-produced in the form of the Hobie Cat.
List of reasons why catamarans have trampolines:
- Lightweight material
- Drains immediately
- Low wind resistance
- Expands the deck area
- Comfortable living space
Catamarans are built as lightweight as possible to maximize performance. The trampoline is made of mesh that weighs almost nothing compared to solid materials, so it is an excellent way to spare some weight.
The nose on a boat is always very exposed to seawater, which often comes in over the boat. When most of the front consists of a net, the water will automatically drain off.
Low wind resistance
Another great feature of the mesh is, that it has almost no wind resistance. This will affect the speed of the boat.
Expands the deck area
Catamarans are build from two hulls with each their deck area. So the trampoline gives a lot more usable space in the front of the boat, without harming the boat performance.
Comfortable living space
A trampoline is a part of the living space on a catamaran, on which you can sit, lounge, or lay down comfortably.
It works a little like a hammock and supports the body very well when the boat moves up and down with the waves.
What are trampolines for catamarans made of?
The mesh is either knitted or knotted from polyester, polypropylene or polyamide line. In some cases Dyneema is used to make it extra strong.
You can also find vinyl type trampolines for small day cruiser type racing catamarans, but this material is not permeable for wind and water.
Are catamaran trampolines safe?
All types of mesh for trampolines are very safe, but the securing of the net is often the weakest point. It will increase the safty in many cases, if every ring in the trampoline where tied individually, instead of threaded on with one single line.
How trampolines are installed
How trampolines are installed on a boat depend on the boat model. You will get an idea by watching the below videos.
Can you install a new trampoline yourself?
Yes you can install a new trampoline yourself. In this video Sailing Unwritten Timeline renew the trampolines aboard their 2003 Antares catamaran
Here is a very thorough guide on how to sew a trampoline yourself.
