Our Technology

Vacuum Infusion Process

At Lindell Yachts, our goal is to build the absolute highest quality boats available. That means using the best composite manufacturing processes and choosing the latest and most proven technologies.

For composite boat building, most companies use traditional “hand laid” methods for laminate construction. This is an old process that dates back to the very beginnings of fiberglass composite construction. Fiberglass roving is “laid down” by hand and then paint rollers soaked in resin are use to apply the resin over the fiberglass and soak it through and through. This is done with each layer until the desired thickness is reached. The advantage? It’s fast! And your polyester resins are less expensive. You can layup a hull and deck very quickly so that you can move on to the next one. Sounds great if you are a high volume boat production company looking to make your boats as fast as possible.

So what’s the problem with this technique? Simple, too much weight and not enough strength. It’s impossible to achieve the optimal ratio of fiberglass to resin using this traditional technique. As a result, these boats are heavy with resin and decreased in overall strength. You can make them look pretty on the outside, but the final product compromises the two most important aspects of the boat: weight and strength.

At Lindell Yachts, we don’t make compromises to quality. Period. We have perfected a much more difficult, but completely different and superior composite manufacturing process. Our process utilizes 100% vacuum infusion with vinylester resins (which also offer superior resistance to abrasion and blistering). Some companies will use vacuum infusion for a few of their smaller parts (e.g. transom and bulkheads). But Lindell Yachts uses vacuum infusion for every part of the entire boat: hulls, decks, liners, roofs, and all of the smaller parts. Everything. No compromise.

Vacuum infusion is a process that involves laying up all of the composite materials dry, including the fiberglass roving and the core (and we use only the highest quality Corecell core). Once the dry materials are entirely laid up in the mold, the composite and mold are covered by a plastic bag that utilizes a specially designed resin distribution system. When everything is covered by the bag, a strong vacuum is applied to the system (26mm mercury) evacuating all of the atmospheric air. The resin is then “sucked” into the composite materials within the mold replacing the air that was removed. Since it is applied via a vacuum, only the optimal amount of resin can interact with the composites. The perfect ratio of fiberglass to resin is achieved every single time. And the final result? A consistent weight savings of 30%, while increasing the boat’s strength by 150%. Wow! Not compromising has a payoff.

So why then doesn’t everybody use this process? As you can guess, it is time consuming and requires years of expertise and refinement. The composite parts also require more cosmetic finishing work once out of the mold. Again, more time and detailed work, but a superior product through and through. No compromise. And finally, vacuum infusion is significantly better for the environment. All of the byproduct styrene gases are trapped and filtered within the vacuum rather than released into the atmosphere. Again, no compromise from beginning to end.

Volvo Penta IPS

Lindell Yachts has partnered with Volvo Penta to offer the latest technology for marine propulsion. The Volvo IPS stands for “independent propulsion system” which Volvo introduced over 10 years ago. This system utilizes two individually steerable pod drives under the hull. Each pod can be articulated independently to direct propeller thrust wherever you need it, so no rudders are required. This flexibility enables the boat to maneuver like no other. Now it is possible to literally spin in the boat’s own length, turn 90-degrees on a dime, and carve tighter turns at speed.

The pods are easily controlled by a joystick, so maneuvering is as simple as pushing or turning the stick in whichever direction you want the boat to go. This makes it possible to dock in a new and completely intuitive way, no more opposing the engines and jockeying the throttles to back into a slip or make a tight turn in the marina basin.

We offer several smart features as part of this system, such as:

Dynamic Positioning System – Just press a button and the boat uses a combination of GPS, electronic controls, and the pods to maintain an exact position in the water, constantly compensating for the forces of wind, waves, and current. This is just what you need when you’re preparing for docking, waiting for refueling or for a bridge or lock to open.

Slow Troll Mode – With this low-speed mode, you reduce boat speed at idling by 50% – during testing we averaged 1.6 knots on two engines and 0.3 knots on one. . Perfect when you’re driving in marinas and canals. Total system integration gives seamless operation with the standard controls.

Sportfish mode – Developed exclusively for Volvo Penta IPS, the Sportfish mode will add to your big-game fishing. This makes it possible for you to rapidly turn your boat around its own axis – and follow the fish at high speed in reverse, using only the engine controls – to ensure a successful catch.

The latest generation of Volvo Penta controls has integrated buttons for Low-speed mode, Single-lever mode and Cruise control, making it even easier to enjoy boating.

The unique design of Volvo Penta IPS makes a huge difference when it comes to performance, emissions and onboard comfort:

  • 30% reduced fuel consumption
  • 30% less CO2 emissions
  • 50% lower perceived noise level
  • 40% longer cruising range
  • 20% higher top-speed
  • Safe and predictable handling
  • Joystick docking

Volvo’s forward facing pod drives allow for continual clean water to the propulsion system to achieve maximum performance and efficiency. To protect the forward facing propellers, Lindell Yachts has designed a forward fin in front of each pod to deflect any debris or even large objects.

The Volvo Penta IPS is the modern inboard system, superior to inboard shafts in every vital aspect including handling, onboard comfort and performance. Those benefits have made it by far the most popular pod system for leisure boats.
