Technical fabric, net, or custom-made trampoline:
Defining the best solution for your boat.

Trampoline for catamaran

Choosing the material

Recommending the right net or the right canvas is the result of researching the best characteristics of the materials available, based on our customers' specifications. Among our customers main criteria, the most common are the following:

  • Aperture ratio and permeability,
  • Robustness,
  • Ability to hold up in marine environments,
  • Comfort,
  • Design,
  • Price.

This Buyer's Guide will present the products, materials, their technical characteristics, their fixation methods, maintenance, and more, to assist you in narrowing down your search for the right trampoline for your boat.

Our team can then advise you accordingly and draw up a personnalized quote. To request a quote for a trampoline or technical fabric for your habitable multi-hull, or a custom-made trampoline, please contact us by e-mail or phone on +33 5 56 36 04 62.

Braided netting or technical fabric ?

Below is a summary of the advantages and disadvantages of rope nets and technical fabrics:

*Shelf life: tested with boat charterers in the French West Indies and French Polynesia.

The research carried out in collaboration with our suppliers, and the testing and observations made by both professional and non-professional skippers have resulted in the selection of a line of technical fabrics, and a line of rope nets. This offer is not exhaustive and perpetually evolves with the development of new materials.

Technical fabrics

The main advantage - and the most sought after - of trampolines made of a technical fabric is their comfort. Whether you are barefoot, or sitting or lying down, technical fabric trampolines are excellent for relaxing and lounging. They also considerably increase the boat's surface area (by close to 20%!) for very pleasurable moments of coastal sailing.

Although they share similar designs and manufacturing processes, there are varieties of technical fabrics with different characteristics corresponding to specific uses for each multi-hull. The material, mesh, and openings in the net cells, are just some of the parameters that define each product. These fabrics are commonly called Grid. Technical fabric trampolines have reinforced edges often made of canvas and a strap. This technique makes them adaptable to a wide variety of shapes and different fixation systems that use grommets, bolt ropes, snap rings, slats, or straps. Furthermore, these fabrics may have one or several sides having no tension system.

Therefore, they are adaptable to all types of shapes with a wide variety of fixation systems.


Reference : MT392

This material's permeability makes it highly resistant to rupturing and tearing.

Our technical specifications rest on the ability of a fabric and its fixation system to bear the weight of an entire crew. One particular advantage is that this fabric is welded, to cover large areas.


Reference : MT492

The technical design and materials used in this fabric make it extremely resistant, capable of withstanding 5 tonnes per m².

This fabric is commonly adapted to trampolines on large sailing vessels of over 35 feet, including the largest multi-hulls. Its void ratio greatly reduces resistance to waves. Each fabric is also welded, to cover large areas.

Technical fabric edges with grommets

With a diameter of less than 17 mm, made of stainless steel and equipped with a toothed washer to fasten the reinforcements, grommets are the most common way to lace up the trampoline. The grommets mustn't be positioned too closely together to evenly distribute the weight and tension of the trampoline.

Multi-hull nets

Knotted nets are traditionally used on habitable multi-hulls. Their main advantage is their void ratio - or large openings - offering little resistance to waves. With evolving knotting and braiding techniques, we obtain braided netting as resistant as knotted netting, with outstanding levels of comfort.

Our selection of multi-hull nets have different thread diameters, mesh sizes, and braidings. The nets listed below are made of polyamide, polypropylene, and multi-strand polyester, capable of lasting a long time in a marine environment made of UV rays and salt. For that matter, they are treated against UV rays.

Nets and comfort

This diagram will allow you to rapidly compare our two types of nets, each with a different mesh-link system:

  • The braided net is designed for relaxing.
  • The knotted net is designed for guard rails and storage areas on board.

The net edges

The edges of our nets are made of a 10-mm or 12-mm, UV-resistant, polyamide bolt rope, reinforced by a small nylon cable. This rope is tied to the net when the net is tensioned and cut to the size of the boat. This way, it will fit in the designated area, giving it a distorted appearance when not in use.

The main advantage of a bolt rope, aside from its robustness, is that it can be laced through every aperture all around the edges of the net to make it easier to fasten to the boat. What's more, the net fits curved shapes very well.

Your project in 4 steps

Step 1 : Quote

During our first contact (via our web site, phone, or email), we ask you a certain number of questions in order to draw up a quote.

  • Make and model of your boat
  • Precise void measurements (sides and diagonals)

This quote is drawn up as precisely as possible based on the information provided. The quote gives detailed information (technical details, photos) for each material so that you have all the parameters to make the right trampoline selection. This quote will be emailed to you.

Step 2 : Plans - Dimensions

Since we design custom-made trampoline nets, it is important for us to have very precise information before we begin our manufacturing process.

That is why we need to insist on discussing your net with you to validate the information you've provided us. At this stage, each customer needs to sign off on the information he / she has provided. This does not prevent us from validating the plans of a standard boat, if they are available to us.

An increasing number of shipchandlers make their plans available to us, and we rely on their documents. However, certain boat plans are out of date or have been modified, which is why your boat is our top priority.

Step 3 : Manufacturing

Once we have your written acceptance of the quote and the information received, we begin designing your trampoline(s) and keep you updated on their progress. Based on the nature of the project, we may ask you to validate certain steps of the manufacturiing process. Generally, manufacturing times are between three and four weeks (summer season excluded).

Step 4 : Shipping

After a final product control regarding its design and dimensions, we carefully package and ship your trampoline(s). The installation instructions are emailed to you. And of course, we remain available for any installation questions you may have.
