Welcome to ALFAB’s video presentation on how a well-designed portlight can add style and functionality to modern vessels. Today, we’ll delve into the historical uses and designs of portlights and portholes, explore the development of the world’s newest premium in-glass portlight by ALFAB, and discuss the essential uses and importance of portlights in contemporary vessels.

Portlights have been a crucial feature on ships for centuries. In the past, they were often simple, small openings with shutters or covers to allow light and fresh air into the ship’s interior. These early designs served practical purposes, providing ventilation and natural illumination, but they also had limitations in terms of style and aesthetics.

 Over time, shipbuilders began to experiment with designs, incorporating various shapes and materials to improve functionality and appearance. The evolution of portlights played a significant role in maritime history, influencing both the aesthetics and functionality of vessels.

 Today, ALFAB is proud to introduce the world’s newest premium in-glass portlight, representing a breakthrough in design and technology. Our team of experts has meticulously designed, produced, tested, and certified this innovative portlight, setting a new standard for the maritime industry.

ALFAB’s commitment to excellence is evident in every aspect of our portlights. The in-glass design seamlessly integrates with modern vessel aesthetics, offering a sleek and sophisticated look while maximizing functionality.

Our portlight’s advanced materials and construction ensure durability, longevity, and resistance to the harshest maritime conditions. Rigorous testing and certification procedures guarantee top-notch performance and safety.

In modern vessels, portlights continue to play a pivotal role. They serve as sources of natural light, reducing the need for artificial lighting during the day, which is not only energy-efficient but also creates a pleasant onboard environment.

Additionally, portlights promote ventilation, helping to maintain a comfortable and healthy interior atmosphere by allowing fresh air to circulate freely. This is especially important during long journeys or when vessels are docked.

Furthermore, portlights offer passengers and crew members stunning panoramic views of the surrounding environment, enhancing the onboard experience. Whether it’s the beauty of the open sea, a bustling port, or a tranquil sunset, portlights provide a connection to the world outside.

In conclusion, ALFAB’s premium in-glass portlights combine style and functionality, paying homage to the rich history of maritime design while embracing the latest technology. These portlights are not just essential for ventilation and natural light but also elevate the onboard experience, offering passengers and crew members a breathtaking perspective of the world beyond.

After purchasing a previously-owned sailing Catamaran, Denham Hitchcock, a correspondent for the Channel Seven Network, discovered while living aboard the vessel that her current windows were not as functional as they could be and also were not marine-safe.

The original boat builder had simply left panes of perspex with basic lock-in handles, unable to be opened. Therefore they would need to be removed and stored away before pulling anchor in order to ventilate the cabin. Prior to removal, it was difficult to see the chart plotter or even see through the front windscreen. As any boaty knows, ease of use and visibility are the most significant advantages when operating a marine vessel safely.

The Perfect Solution

The team at ALFAB were keen to work with Mr. Hitchcock in designing new custom marine windows that would remedy all of the issues he was facing. Hitchcock knew just how he wanted his new marine windows to function and was able to provide both a rough template and measurements to our experienced designers. He required sleek lockable sliding windows that would fit in the vessel’s existing window frames while taking up minimal onboard space.

Once manufactured, the window installation process was a breeze thanks to the cutout nozzle provided by ALFAB that allowed them to pop into place as though they were always meant to be there.

Mr. Hitchcock reported that aside from the safety concerns that the custom retrofitting solved, he can also allow for better temperature regulation now that the windows can be opened, ventilate cooking fumes without having to wait for them to make their way to the hatch and feel confident that his vessel’s overall aesthetic has improved.

“I wouldn’t hesitate to recommend Alfab in Brisbane to anyone looking to improve their boat with some professional looking windows for a fair price. Bloody terrific!” Denham reiterated.

DIY Installations

Owning a boat is a big commitment, it takes a lot of work to maintain a vessel of any size and there are many elements that need regular attention. Many boat owners end up becoming DIY experts, turning their attention to all sorts of tasks that they may never have attempted before. However, boat window replacement is not something to be taken lightly and can be a big job, even for those with experience. This is one job that you want to ensure is done right as you don’t want to end up windows that don’t fit properly and allow water to seep into your boat, potentially causing structural and interior damage.

First of all, to order a new window or set of windows, you’re going to need precise measurements. This can be a difficult task, since providing builders / glazier with 100% accurate measurements can be challenging. For accurate numbers be sure to remove the existing windows and clear all gaps before measuring. If you or the boat builder still has access to the original plans, this is the best option, as you’ll have precise measurements. If you’re planning on having custom windows made, it’s very important to provide this data to get an accurate estimate of the cost of the project.

Boat Window / Windscreen Options

When you’re shopping for new marine windows or boat windscreens, you should be looking for a mix of safety and comfort. This means that you’re going to want to look for a mix of fixed, hinged and sliding windows to install throughout your boat.

You also have to take into account the thickness of the material. While there’s no clear standard for personal yachts and boats when it comes to window thickness, it’s better to determine what thickness you feel safe with as well as what kind of tint you may want.

Finally, pick a frame that suits the overall look, feel and aesthetic of your boat. You will want to choose a design that flows well with the curves and lines of your vessel and complements what is already in place. Your boat windows can be as much or as little of a feature as you choose and your frames will go a long way to achieving the look you want.
