Construction Approach

 Construction Approach

Bering Yachts prides itself on building robust, steel-hulled yachts with an emphasis on reliable, easy-to-access machinery. This mindset starts below decks and works its way throughout all ship systems.

The roots of Bering’s design and construction approach lie in modern steel North Sea commercial ships, which are built to highly-regarded Scandinavian naval architectural standards. These ships, able to withstand the severe storms and icy conditions of the Baltic and North Seas, set the standard that Bering Yachts founder Alexei Mikhailov follows in his mission of creating semi-custom heavy steel expedition vessels that provide safe and stable rides.

Bering Yachts subscribes to specific build principles to create what we feel is the most capable and reliable motor yacht possible. Our hull designs are based on those that have stood the test of time in the commercial marine industry. The use of Lloyd’s-certified A36 marine-grade structural steel in the hulls and decks creates an extremely strong and reliable vessel. Additionally, the use of steel allows tremendous flexibility with the placement of interior bulkheads, thereby providing a great deal of customization with the floor plan.

Why We Build with Steel

Bering Yachts are designed for extended voyages on the open ocean. When facing heavy seas, your Bering will provide both the safety and comfort you would hope for in such demanding conditions. This is precisely why we selected steel as the material of choice. Steel fleets dominate the world’s navies, research vessels and commercial marine operations, as well as expedition cruising yachts. And steel provides the strongest ratio of benefits of all available shipbuilding materials: strength, durability, ease of design and customization, fire resistance, ease of maintenance and repair, abrasion resistance. These characteristics make steel suitable for serious offshore vessels.

Strength

Steel’s mechanical strength properties have made it the overwhelming choice for building commercial and military ships around the world. From breaking ice to withstanding groundings on rocky shoals and reefs, steel ships have a longstanding history of taking severe punishment of the worst kind, and despite the abuse, retaining both hull and watertight integrity. Steel vessels have safely seen their crews through some of the most extreme and challenging situations imaginable (read The Grey Seas Under by Canadian author Farley Mowat — the story of North Atlantic salvage tugs, all made of steel — and you’ll understand why). That fact alone gives us tremendous confidence that steel is the correct material for building our customers’ yachts.

Bering hulls are extremely impact resistant. Steel by its very nature is also puncture resistant, hence its use in safes and vaults. These hull properties, together with appropriately-engineered hull plates, which are then reinforced by internal structural members, cross bracing and bulkheads, raise the likelihood of impact survival; be it a rogue floating shipping container or a log, the threat of damage to the hull integrity is decreased. Counter intuitively, steel is quite flexible in nature, so instead of cracking and shattering like fiberglass might, it’s more apt to dent and deform upon impact.

Abrasion Resistance

There are countless examples of steel-hulled vessels running aground on a rocky shore and suffering only minor damage with the integrity of the hull remaining intact. Given the diversity of cruising grounds and the fact that you simply cannot avoid every coral head or unmarked shoal, having a strong, abrasion-resistant hull provides valuable peace of mind.

Flammability

Steel does not burn. Many of the materials aboard Bering Yachts, such as coated wooden bulkheads, carpeting, curtains and cabinetry, are either nonflammable or flame resistant. The insulating foam that occupies the space between the hull and living quarters does not support combustion. The marine-ply bulkheads are highly flame resistant. The total flammable mass aboard is actually quite small, therefore much easier and quicker to extinguish should a fire occur. Bering also ensures that each cabin and the engine room and machinery spaces are equipped with temperature alarms and smoke detectors.

Repairability

Steel offers several key benefits when considering repairability. Given that it is one of the most common raw materials in industrialized and even semi-industrialized nations, access to those who understand its repair techniques is widespread A welder possessing even modest welding skills can provide a reliable patch to get you back on your way. Having a steel vessel simply increases the likelihood that should a simple repair be needed, it will not turn into a time consuming and costly headache in an otherwise beautiful cruising locale.

Customization

Bering’s steel-built yachts offer a tremendous level of customization. A steel vessel is built from the keel up according to design plans that allow for near infinite flexibility in the interior layout. Unlike other build materials, steel-built yachts achieve their requisite rigidity and strength throughout the hull and its carefully placed load-bearing longitudinal stringers and cross members, as well as the hull-to-deck joint. This allows for bulkheads and floor plan considerations to be modified virtually at will without concern for adversely affecting the overall integrity of the vessel structure.

Requiring tremendous skill and experience, both to properly engineer and design and then to physically fabricate each vessel, Bering employs highly educated draftsmen and experienced shipwrights who have honed their skills successfully building commercial ships of all sizes.

Engineered for Safety

Recognizing the need for ultimate reliability and functionality, Bering uses rugged commercial-grade equipment and fittings aboard its yachts. Internationally sourced continuous duty pumps and motors are found in the plumbing and electrical systems. Cummins Marine diesel engines are typically installed due to their longstanding track record for dependability and performance, as well as their unequaled international service network. And, in keeping with our belief in redundancy, Berings are equipped with twice the needed life-raft capacity included in the specifications.

All Bering Yachts are built to CE Ocean A sea state endurance standards, even if the vessel is not destined for sale in the European Union. Detailed stability calculations are carried out for each Bering and provided with each vessel. Bering vessels can also be built to comply with most classification standards, where applicable, upon request. Internationally recognized standards include those set by the American Boat & Yacht Council, American Bureau of Shipping, and Lloyd’s Register.

Full Displacement Hull

When we decided to build our first motor yacht, we chose as our prototype a 65-foot Norwegian fishing trawler design. Vessels of this type have been used aggressively for decades and have proven themselves to be safe and efficient fishing platforms. We left the hull form untouched and developed a superstructure and interior that enhances accommodations for long-term living aboard and cruising. The result of this collaboration is a bold, seaworthy passagemaker that not only meets stringent commercial safety standards but provides a pleasant and reassuring underway experience in any sea state.

It’s been said that the ocean never changes, we just change around it. While designers use exotic materials and novel design concepts to seek the perfect hull form that will somehow finally conquer the challenges of Mother Nature, the fact remains that hydrodynamics do not change. Decades of real-world experience shows that a heavy, full displacement vessel with carefully designed centers of buoyancy and low centers of gravity will provide a truly comfortable, stable and safe passagemaking experience.
Bering trawlers are heavy, full displacement vessels designed with a hard-chined hull; this is the most common hull form in commercial fleets. This type of hull shape, unlike those with rounded chines, helps minimize roll and increases the stability of the vessel at rest and while underway. We are proud to say that our boats are heavy. Marketing by current builders may have you believe weight is an enemy to a properly designed boat. Once again, it all comes down to what you are designing for; if the design criteria calls for planing speeds and trailerability, then yes, lighter is better. But when we are speaking of vessels that will go to sea for extended periods, thus being exposed to potentially dangerous and uncomfortable sea conditions, weight quickly becomes your ally.

Among other benefits, a properly balanced, heavy, full displacement boat will possess a slower roll moment. A vessel that rights itself too quickly is one of, if not the leading cause, of seasickness. A “snappy” or abrupt roll moment is not only uncomfortable to the crew, but it adds dynamic loads to the vessel and its systems. The contents of tanks splash harder, unnecessarily stressing the walls and lids. Heavy machinery and equipment such as engines and battery banks generate large amounts of inertia with a snap roll moment, as well as imparting additional loads on running and steering gear, all of which leads to excessive wear and premature failure.
A smooth ride is paramount in helping ensure both crew and ship arrive safe and sound at their destination, and a heavy boat, with or without stabilization, will afford a level of passive stability that no light-for-displacement vessel can provide.

Bulbous Bow

The bulbous-bow designed hull plays an important role in Bering’s construction approach. Bulbous bows help to reduce pitching in heavy seas, and in conjunction with the forward watertight bulkhead, create a collision compartment that provides an added level of safety. Bering’s custom bulbous bow, with integral bow thruster, has a sharper vertical entry than most bulbs. The purpose behind this design is not only to draw the bow wave lower at the waterline, but to minimize the pressure coefficient along the side of the bulb. Furthermore, the bulb is ballasted to reduce pitching in heavy seas; another benefit is that it serves as a collision compartment in the event the vessel collides with a floating or submerged object.

Two massive gondola skegs act as passive stabilizers, reducing roll, increasing course stability, and protecting the propellers and rudders. They’ll also allow the vessel to sit upright, if beached, giving the Bering hull the ability to rest on her own bottom if needed for hull inspections or simply bottom cleaning.
The shafts and propellers are housed within skegs that provide increased directional stability and will improve course keeping should it be necessary to run on one engine.

Watertight Bulkhead

You can take comfort while at the helm or anywhere aboard a Bering, knowing that all our yacht hulls are divided by five watertight bulkheads creating six independent compartments.

Also, Bering designs all tanks to be integral, meaning they actually double the sides of the hull. The lids of the tanks are heavy steel plates that have been welded to the hull sides to form a completely liquid-tight structure. In addition to maximizing otherwise unused space, and providing the lowest center of gravity possible, integral tanks provide a very significant safety advantage. Essentially, a Bering trawler has a double hull, meaning that should the hull itself somehow be penetrated below waterline, the tank would maintain the watertight integrity of the ship. This is an extraordinary feature not found on most recreational cruising yachts.

Hybrid Hull Design

Bering’s hybrid hull design is one part round bilge, one part hard chine and one part dual skeg protection. The result is better passive stabilization by presenting the buoyancy of a hard chine to resist lateral rolling motions but still maintaining the dampening characteristics of a round bilge hull. This can be most effective at anchor or in a beam sea. For every new yacht built, Bering carries out extensive hydrodynamic hull 3D modeling and calculations to perfect the hull design and reduce fuel consumption.

Long-Range Capabilities

Our hull design allows for greater fuel capacity. And, our yachts’ engines are typically selected for fuel economy; Additionally, the hull shape allows for more voluminous interior space, including an engine room that can accommodate additional equipment such as water makers and generators and inverters. With many expedition-style yachts, comfort and accommodations take a back seat to purpose or utility, resulting in minimal storage capacity. Bering’s are built with world cruising in mind, so ample space is dedicated to provisions, wardrobe, storage and accessibility. On a long passage, you don’t just live on a boat — you have to live with it. Bering Yachts are designed to have more range, be more fuel-efficient, and provide more space for live-aboard cruising.

Silent, Vibration-Free Ride, Low Decibel Readings at any Speed

Controlling noise and vibration on a long-distance passagemaker is extremely important as the crew will be exposed to ambient noise while underway for long periods of time. Bering goes to great lengths to ensure that its vessels are quiet by using cutting-edge insulation technology for suppressing the high frequency noise.

Bering trawlers are built with Seatorque shafts, one of the most quiet and most vibration-free running gear systems available. As you can see in the spreadsheet below, the decibel reading in the pilothouse of a Bering 65 is 48 dB while running at 1200 rpm and traveling at 8 knots, while the engine room is 91 dB. On a Bering Yacht, it’s quiet enough to hear the water passing by the hull, rather than the sound of machinery.

The decision to commission a new Bering offers you an incredible amount of choices

Construction of a new passagemaking trawler yacht allows the owner to make informed choices and to select the gear, equipment and layout that is most suitable for their application. Bering Yachts is extremely flexible in working with clients to specify every aspect of the build. Savvy buyers create comparison spread sheets to look at competing models side by side. We encourage you to do this and are confident that every Bering we offer will meet or exceed the detailed analysis you develop to create your ultimate passage making vessel. Production fiberglass models are limited in construction to what works within the limitations of their molds, a custom steel Bering has virtually unlimited possibilities and everything can be reviewed through our 3D modeling before the first piece of steel is cut. If you are looking to build the ultimate cruising vessel, you owe it to yourself to connect with Bering Yachts, and to learn how we can build you the boat you desire, at an attractive price with outstanding performance and reliability.
