Naval architecture is an engineering discipline dealing with the design, construction and repair of marine vehicles. Image File history File links No higher resolution available. ... Image File history File links No higher resolution available. ... Paddle steamers — Lucerne, Switzerland. ...


Due to the complexity associated with operating in a marine environment naval architecture is by necessity a co-operative effort between groups of technically skilled individuals that are specialists in particular fields, often co-ordinated by a lead naval architect. This inherent complexity also means that the analytical tools available are much less evolved than those for designing aircraft, cars and even space craft. This is due primarily to the paucity of data on the environment the marine vehicle is required to work in and the complexity of the interaction of waves and wind on a marine structure.


The areas of expertise filled by naval architects are typically:

  • Hydrostatics (ex: trim & stability)
  • Hydrodynamics (ex: resistance and powering, seakeeping, manoeuvring)
  • Arrangements (ex: concept design, volume & access)
  • Structures (ex: global strength, seaway responses)

The art of naval architecture

Venetian gondola

Traditionally, naval architecture has been more art than science. The suitability of a vessel's shape was judged by looking at a half-model of a vessel or a prototype. Ungainly shapes or abrupt transitions were frowned on as being flawed. This included, rigging, deck arrangements, and even fixtures. Subjective descriptors such as ungainly, full, and fine were used as a substitute for the more precise terms used today. A vessel was, and still is described as having a ‘fair’ shape. The term ‘fair’ is meant to denote not only a smooth transition from fore to aft but also a shape that was ‘right.’ Determining what ‘right’ is in a particular situation in the absence of definitive supporting analysis encompasses the art of naval architecture to this day.

Low-cost digital computers, dedicated software combined with extensive research to correlate full-scale, towing tank and analytical data has increased the ability of a naval architect to more accurately predict the performance of a marine vehicle to a much higher level of accuracy than previously. These tools are used for static stability (intact and damaged), dynamic stability, resistance, powering, hull development, structural analysis, etc. Curiously, analytical tools (such as Computational Fluid Dynamics) are still having difficulty in predicting with absolute certainty the response of a floating body in a random sea. The challenge is being addressed by universities, towing tanks, etc. throughout the world. Data is regularly shared in International conferences sponsored by RINA, Society of Naval Architects and Marine Engineers (SNAME) and others.

The Naval Architect

A naval architect is a professional engineer who is responsible for the design, construction, and/or repair of ships, boats, other marine vessels, and offshore structures, both commecial and military, including: Professional Engineer is the term for registered or licensed engineers in some countries, including the United States, and Canada who are permitted to offer their professional services directly to the public. ...

Modern engineering on this scale is essentially a team activity conducted by specialists in their respective fields and disciplines. However, it is the naval architects who often integrate their activities and take ultimate responsibility for the overall project. This demanding leadership role requires managerial qualities and ability to bring together the often-conflicting demands of the various design constraints to produce a product, which is "fit for the purpose."


In addition to this leadership role, a naval architect also has a specialist function in insuring that a safe, economic, and seaworthy design is produced.


To undertake all these tasks, a naval architect must have an understanding of many branches of engineering and must be in the forefront of high technology areas such as vessel arrangements, hydrodynamics, stability, and structures. He or she must be able to effectively utilize the services provided by scientists, lawyers, accountants, and business people of many kinds.


Naval architects typically work for shipyards, ship owners, design firms and consultancies, equipment manufacturers, regulatory bodies, navies, and governments.
