Why Do Catamarans Have Trampolines? (Reasons & Differences)

I’ve never heard of anyone who didn’t find the trampoline on a cat quite romantic. After all, you can watch the sunset while having a sip with your partners or lie under the stars at night. Oh, did I forget to mention sunbathing during the daytime?

Why do sailing catamarans have trampolines? The trampoline on a cat serves a number of purposes, both rational and fun activities. 

Sailing catamarans with a trampoline deck rather than a solid one is an easy solution to lower their weight and free up additional deck space. When the cat faces big waves, the trampoline on the front lets the waves pass through quite effortlessly and lends the vessel more stability.

Why Do Catamarans Have Trampolines? (The 3 Reasons)

1. Weight reduction

There’s a significant weight saving by using a trampoline instead of a solid frame. Open weave or closed mesh, no matter which trampoline you choose for the catamaran, the weight will be lighter than solid wood or metal deck.     

2. Maintain Stability

Water can pass through the trampoline. It’s a good idea to have a robust structure on the deck if you’re going to face high waves. When it comes to big seas and catamarans, this is crucial. When the boat reaches the bottom of the wave, it is possible that the bows will be buried, adding weight to the bow as the boat brakes and the wave pushes it further deeper. 

The pressure on the bow must be relieved as quickly as possible at this point. Water must pass over and around the boat, which takes time in a circumstance like this where time is a precious commodity.

Since an empty hole in a trampoline’s net isn’t part of the bow, the water’s weight cannot be as much as it would be if it were in a boat. So, this area is deducted from possible square meters of pressure.

Because the region where water can remain has been reduced, but also because water now has a second alternative, it now has more options. There will be a shorter period during which a large wave could potentially overturn the bows. 

It’s essentially a fishing net in disguise. During a rough sail, the hull may be pushed outward by an outward force. This adds structural integrity. To combat this, the net is tense. The cross beams, which are the primary supports, also offset this force.

3. Adding a Touch of Zen

Use the trampoline as a sunbathing platform or just a place to relax and take in the ocean views. Metal or wooden decks are annoying and uncomfortable to sit on, so you’ll need cushions, sun protection, and a variety of additional items to make the experience more bearable. 

Trampolining is a great way to unwind without having to go through any additional hassle. On the other hand, the social features of sailing on a large deck could be game-changing. 

To get the most out of your trip, you should book a boat that isn’t used to crossing the Atlantic weekly. I prefer trampolines for coastal sailing and a sturdy deck for rough waves.

Differences among catamaran trampolines

When it comes to catamaran trampoline knitting properties, you may be able to locate two alternative options on the market. Here they are:

  • Trampoline with an open weave
  • Closed mesh.

Quality and knitting are the hallmarks of open weave trampolines. Large perforations at the bottom allow water to swiftly drain away. It’s a better alternative if you’re encountering rough and choppy seas.

Trampolines with a closed-mesh design are easier to walk on. The knits are arranged in a crowded fashion. The visual appeal of this trampoline is excellent, but draining the water takes a long time.

As a result, if you’re sailing a catamaran with a tight mesh trampoline, you may have to make accommodations while encountering large waves.

Building materials and quality now vary, including: 

  • Polyamide 
  • Dyneema Netting Polyamide
  • Netting made polyethylene & polyester  
  • Webbing 
  • Mesh varieties

Dyneema stands out as the most promising of these alternatives. It will be long-lasting and resistant to abrasion. However, you’ll have to fork over a little additional cash to get these kinds of netting.

Catamaran Trampoline Care And Upkeep

To get the most usage out of your catamaran trampoline, you need to use it frequently, take good care of it, and install it correctly.

Correct Installation

If you want your trampoline to last, it must be installed correctly. The framework will be properly supported if the trampoline is deployed correctly. 

As a result, if the trampoline is not installed correctly, it will become loose and saggy and lose tension and stability. So monitoring the trampoline’s tension and resistance, as well as the quality of the knits and joints, is a necessary step.

Material selection

There is a good chance the trampoline will be in direct sunlight. The effects of the sun, UV radiation, sea salt, and water on its lifespan will be significant. To extend the life of a trampoline, it’s important to use UV-resistant materials.

If you see any signs of rust or frayed cords, it’s time to evaluate whether or not the trampoline can be salvaged or if it needs to be replaced.

Limiting the Load

Excessive use will inevitably shorten the lifespan of the trampoline. The trampoline joint and fibers will deteriorate if they are overloaded, therefore exercise caution when using them.

Trampoline Helps Prevent Catamaran From Capsizing

Two hulls make up the catamaran. Sailors benefited greatly from the catamaran’s improved stability and maneuverability as a result of this particular design. To fill the space between the hulls, an inflatable trampoline is used. 

This raises the question of whether the catamaran will be prone to flipping as a result of this. To flip a boat, the center of buoyancy and the center of mass must be out of balance. The two hull designs of catamarans, however, ensure their stability. 

With the trampoline, you don’t have to worry about the wave’s overturning force because it passes through the trampoline.

Now you may declare with confidence that the catamaran boat will not readily flip.

Can I DIY a Cat Trampoline?

Installing a trampoline can be a do-it-yourself project. Leave the installation to the professionals, though, if you’re not knowledgeable. Too many things are at stake here, including lives. 

Cat Trampoline Installation

Installation processes will differ greatly depending on the type of nets, boundaries, attaching hardware, and type of boat.

  • To ensure proper orientation, lay the new net on top of the old one.
  • Make sure that the net is secured in place by attaching temporary lines to the corners and tying them to the structure somewhere.
  • Clear off all of the lacing points by taking out the old net.
  • Running the lacing line through the grommets and lacing points in the appropriate pattern, begin at a corner and work your way outward.

Because the lacing space is greater, if the line is pre-cut, it may not go the complete length aside. Take it to the limit and tie it off. Keep the lacing line loose with a bigger lacing gap rather than tightening it.

  • Once the first side of the net has been maintained by a loose lacing line, proceed to the second side of the net. As with any net, it’s important to wait until all sides are supported before tightening the lacing. 

This is especially true for diagonally oriented nets, which can distort easily and shrink if stretched in one direction. It’s best to begin slowly tightening your laces once all four corners have been supported. 

  • Make sure to use gloves so you’ll avoid getting blisters. You can pull the line from each grommet individually, making sure that you don’t lose any slack as you go. To avoid over-tightening, start with the smallest gap and work your way up to the next one. As the net expands, try to keep it in the middle.
  • Using your feet, walk around the net to make it stretch, and then re-tension it by tugging the line from each grommet in turn, moving the slack down one of the net’s sides. When the net gets too tight, using pliers to hold and tug the line is a good idea.
  • You can adjust the net’s tension by wrapping the line around the grommets on the corners one more time and then tying it off with three half hitches at the lacing point to secure it. When you need to re-tension the knots, you can simply untie the knots.
  • Trim away any extra line, and then either melt or whip the ends to finish them off.

Are Catamarans More Efficient than Sailboats?

Broad reaches and downwind runs are where catamarans typically outperform monohulls. Sailing a catamaran is less taxing than sailing a monohull. Flat-water sailing has several advantages. It is significantly easier to carry tanks and other SCUBA diving equipment on a cat.
