With over 100 technical and white papers published in some of the most prestigious boating magazines and, in many cases, presented at major conferences sponsored by organizations such as IBEX, SNAME, and RINA in the short 30 years since our founding. Our hope in this library is to release quality and relevant information to anyone wanting to learn about naval architecture and marine engineering.
Ship performance is dependent upon resources from ship auxiliary systems that include ship electrical, chilled water, low pressure air, and hydraulic systems. Modern control systems have greatly improved ship survivability over traditional man in-the-loop control.
Running in water makes every boat wet on some level. But, usually, the passengers do not want to experience this wetness. A dry ride is a critical component in a good design, but it is a subjective variable – opinions of the ride can vary greatly.
very Naval Architect who designs planing craft has heard of Daniel Savitsky and his contributions to the field of Hydrodynamics. His 1964 paper, “Hydrodynamic Design of Planing Hulls” is an important piece of work that should be in everyone’s toolkit.
The two fastest yacht projects we’ve collaborated on at DLBA stand out from the norm due to the use of gas turbine power plants. In this paper, we outline the engineering effort undertaken to develop the gas turbine exhaust and machinery space ventilation system for one of these special projects.
As of January 1st, 2021, yachts under 500 gross tons will no longer be exempt from IMO Tier III. This means that vessels will have new requirements imposing stringent limits with regards to Nitrogen Oxides (NOx) levels in the exhaust of marine diesel engines.
Almost all boat owners and operators today are looking for cost reductions. If the owner has a fleet of boats, they are additionally looking for ways to complete the same cost reduction mission, by reducing the number of boats needed in the first place.
A struggle with weight is almost universal – whether it applies to our waistlines, our luggage, or our boats. When it comes to a vessel’s weight, it’s not just the weight itself that’s important but also the center of gravity.
With each yacht’s construction comes a host of decisions that will define the finished vessel. One fundamental decision – and one that will both set the tone for the finished vessel and the build – is basic hull structure. Many factors come into play here, including cost, maintenance, weight, producibility, service life, and tooling.
Two speed gears were introduced commercially in the early 2000s and, although having a relatively small range of application, made a world of difference when used in the right place. The best applications are for very high speed recreational craft, which benefit from the deeper gear to get on the plane, as well as vessels that take advantage of the deeper gear to apply lots of power
