With the Tòpola nautical porthole mosquito net you can relax without receiving visits from unwanted guests

Nautical mosquito net, the complete range

The complete range of our mosquito net for portholes: Tòpola. Click on your favorite model for more information.

Tòpola-rettangolare

Rectangular

Rectangular portholes are among the most common in sailing and motor boats built in the last twenty years. The Tòpola mosquito nets fit easily to the seals of portholes.

Tòpola-rotonda

Round

The Tòpola round mosquito net for nautical portholes is used as protection against the intrusion of unwanted guests into the hold of your boat. It is a light and resistant product.

Tòpola-ellittica

Elliptical

Melyvin’s Tòpola mosquito nets can be made in any shape, just look at our elliptical. The customized profile adapts to that of the porthole ensuring an almost hermetic seal.

Tòpola the mosquito net for nautical portholes

The human being has always sailed the seas to explore and conquer new territories, and transport goods and fish, pushing them to build vehicles and design measures that allow them to achieve the purpose of their businesses.
My name is Vincenzo Avanzolini and I have been passionate about the sea and the wind since I was a child. Passion led me to realise the dream of being able to sail on my own boat which over time also became my first home to which I paid attention, improvements and protection.
The difficulties of those who go to sea are many and require not only physical commitment but also intellectual effort in order to resolve small and large difficulties.
One of these problems is the intrusion into the holds of ships and boats of various animals such as insects or the most feared rodents, capable of making difficult work of transporting goods that must not be contaminated or capable of causing damage to the internal equipment of a vessel.
Living on a boat myself, I have repeatedly asked myself how I could protect “my home” from these probable events. There are several systems on the market that are unfortunately not very satisfactory in my opinion. Solutions such as glues or snap traps which lead to the killing of animals have been discarded out of respect for life. Disc protections on mooring lines to prevent animals from coming back on board are not valid for every situation. The shielding of portholes and hatches with mosquito net-type systems are not sufficiently robust. Those that are robust unfortunately had fixing systems that involved drilling or glueing which could alter the certification qualities of an accessory.
During COVID, I found myself forced to stay on a boat for a long period. I began to think about and design a system that responded to all these issues and at the same time remain simple to use.
In order for the product to be achievable and efficient, I went through the use of different plastic, composite and metallic materials, which from the CAD drawing led me to a prototype that I could test over the last few years.
The following step that led me to the patent process, first recognized in Italy, then in Europe and currently in the U.S. filing phase, was a commitment shared with a group of technical consultants and engineers in the sector.
To expand this project, the next phase involves seeking collaboration with a partner for large-scale production.

processing of aluminum profiles obtained by milling from solid

Tòpola is a 100% Italian nautical porthole mosquito net: from the patent to the creation of the prototypes we used our nautical experience to create a product that is simple to apply, functional and long-lasting. Our mosquito net has been tried and tested at sea.
The union of these elements and the totally artisanal processing of the raw material allowed us to create the first prototypes and move on to the industrialization phase while waiting to find a partner for large-scale production.

  • Patent and 100% Italian product
  • Acquisition of porthole measurements via shipping kit or technical visit on board
  • Transfer to the mechanical workshop for the creation of the template
  • Profile processing machined from solid, anodizing process
  • Production of the relevant fixing pins;
  • Cutting the stainless steel mesh to size
  • Assembly
  • Delivery

Nautical mosquito nets in their infancy, projects dating back to the first decades of the 1900s
