Key Takeaways

  • Catamarans have trampolines to help with weight, stability, and extra lounging space
  • The trampoline serves as a net located in the middle between the two hull designs
  • Whether you choose an open weave or close-mesh you have options to consider
  • Properly maintaining a sailing catamarans trampoline can last up to five to seven years
  • You can install a trampoline yourself but it is recommended that a professional do it

Catamarans have a unique design with plenty of deck space compared to other sailboats. But why do catamarans have trampolines?

The closed mesh trampoline joint on a catamaran serves various functional and leisurely roles. Catamaran trampolines primarily allow water to quickly pass through the two hulls, preventing capsizing, while also serving as a space for relaxation and weight reduction.

To maintain the safety and functionality of trampolines it is essential to conduct routine inspections and perform appropriate maintenance. You should also take into account their varying materials and designs. A catamaran boat needs to have a trampoline for proper boat functions.

Primary Uses for a Catamaran Trampoline

A catamaran has a trampoline connecting between their two hulls. So why do catamarans have trampolines? These are not your typical trampoline that you jump on but rather a strong net material to lie or walk on as you would normally in the deck area.

Reduce Overall Weight

A catamaran trampoline reduces the vessel's weight by replacing a solid deck or metal deck but also offers accessible deck space to reach different parts of the boat. This way boat owners do not have to worry about giving up valuable space when they shed some pounds off of the boat. This also aids in the boat’s performance and allows it to go faster.

As the void in a trampoline net does not count as a section of the bow then the weight of water it can hold is reduced compared to that of a monohull sailboat. The available area for pressure is decreased by this amount due to that reason.

More Stability

Catamaran trampolines offer a major advantage by ensuring optimal drainage and preventing pitchpoling. This is a hazardous situation in which the catamaran flips due to the bow getting submerged. This particular design allows fast water flow and allows the bow to rise and keep the boat stable.

In order to prevent capsizing the boat needs to disperse water from the front before waves pass and hit the back. When the front gets submerged then prompt removal of the downward force is critical. A trampoline lets water flow between the hulls and dissipate downwards to minimize the water accumulation area and shortening the danger period for the front to flip the catamaran unlike a solid deck.

Lay Around, Watch the Waves, Enjoy the Sun

A catamaran trampoline provides a versatile surface for both walking and lounging under the sun. This allows you to admire the ocean scenery and soak up some rays while you lie on them. Keep an eye on the condition of the trampoline since you do not want to be laying on it and it come loose.

Different Options for a Catamaran Trampoline

Several types of trampolines are ideal based on a variety of factors as each have their own advantages and disadvantages to consider. An open weave or a close-mesh trampoline may be present in a catamaran you are looking to buy or already own. Each might have other materials that you should be aware of to know the quality of your trampoline.

Open Weave vs Close-Mesh

The open weave trampoline is a preferable option for harsh sea conditions due to its efficient drainage while the close-mesh trampoline is more suitable for calm waters. This provides a more comfortable surface to walk or rest on particularly for catamarans.

Mesh Materials

The building materials of a catamaran trampoline may require webbing, mesh fabrics like Dyneema, and different types of netting like polyethylene and polyester. Proper trampoline installations of Dyneema netting is critical due to its lack of elasticity which can cause damage to the catamaran's structure.

Dyneema is great for longevity and against UV rays but it is not suitable for lounging or walking since it is generally used in racing boats or high-performance vessels. You can find less expensive and more comfortable materials as alternatives.

Proper Maintenance for a Trampoline on a Catamaran

A trampoline on a catamaran relies on usage and environmental factors for longevity and can cause differing wear rates. Properly installed and high-quality trampolines last for approximately five to seven years. Regular upkeep is crucial but eventual replacement is inevitable.

Inspect for Damage

Trampolines can sustain damage from different sources such as waves, salt, UV rays, and wear from usage. Horizontal trampolines on catamarans located in southern regions are more prone to deterioration due to intense sun exposure and particularly in tropical areas with high UV radiation.

As trampolines, lashings, and attachment points become older, it is crucial to conduct routine inspections. It is important to examine the threads of sewn-seam webbing in addition to your visual inspections.

Further Steps and Thread Type

For optimal longevity of a trampoline you should utilize high-quality PTFE thread, examine ropes for wear and tear, and ensure proper installation to prevent damage from movement-induced chafing. Thicker ropes and heavier materials can increase resistance to UV rays and chafing and can ultimately extend the trampoline lifespan.

Does a Trampoline on a Catamaran Make it Safer than a Monohull Sailboat?

Catamarans and sailboats have distinct hull designs. Catamarans feature two hulls and a trampoline installation that minimizes overturning force by allowing waves to pass through without much resistance. This solid deck design increases contact area with the ocean and results in a better sailing experience.

When comparing the two you can see why a monohull sailboat is more prone to lean and flipping over due to their instability and inability to handle waves' overturning force. Navigating through rough waters demands a vessel that is not only sturdy but also uniquely stable and efficient.

The catamaran fits the bill perfectly since it offers exceptional stability even in choppy seas. So a catamaran is the better safety choice if you want to prevent flipping and best for wind resistance.
