Introduction
MarineWiki is our ambitious initiative to aggregate the extensive know how of our network of professionals in the Marine Industry. This encyclopedia of the Marine Industry will serve as a reference for students as well as practicing professionals.
Description
Naval architecture is a branch of engineering that deals with the design and construction of ships and other marine structures. This engineering is a mix of art and science. Proposing the initial, conceptual design that meets many conflicting requirements is largely art; analyzing and refining it applies techniques based on sound scientific principles.
One of the basic goal of a naval architect is to assure that the vessel will survive any reasonable weather when handled with reasonable prudence, and yet still perform its function efficiently.
Sabyasachi Mohanty, a practicing naval architect defines, " ...when the intricate art of architecture intertwines with the fanciful imaginations of marine structures and economics, what evolves out of this exotic culmination is naval architecture."
On a lighter note, boat building is considered one of the oldest professions along with pottery and prostitution.
Marine engineering is a branch of engineering that deals with the design, installation and even operation of marine machinery. In shipbuilding, marine engineers deals with the design of all machinery systems, in most cases along with the naval architect.

6.2 m Solar BoatAIMThe aim of this project is to design and build a prototype of a boat, which is completely powered by solar. This is the first one among the series solar boats which we are jointly developing with [Team Sustain http://www.teamsustain.com/]. The entire power is supplied by a series of solar panels arranged on the roof of the boat and driven by two electric outboard motors.
DESIGNBasic dimensions of the boat is Length = 6.2 m, Breadth = 2.5 m, Depth = 1 m. Since the boat is entirely dependent on solar power it was very essential to design an optimized hull form. With the help of professional software's we were able to complete this task very fast.
CONSTRUCTIONProject commencement : 13 Nov-2008
Day 1It was a great moment for all of us. This is the First construction project undertaken by us. First job to be finished is preparing the mold. Since the time available was very less we were planing to make a temporary mold using Plywood and wood. We started with making the skeleton structure. Since the depth of the hull is only one meter we were able to get the lines printed on 1:1 scale on A0 sheet paper. Then from these printouts we marked the lines on the plywood. Then the skeleton templates (refer to the pictures)are made from the plywood.
Day 2The templates are prepared for every 250 mm frame spacing. The estimated time for completing all the templates are around three days. Next step is to fix the skeleton templates on the keel structure. This is the most important step as far the construction is considered. Any mistake that happens in the alignment of the templates or in the dimensions of the templates will be directly reflected on the hull shape and consequently on the performance of the boat. All the templates are to be fixed on the relevant frame spacing. Once we have all the templates fixed next step is to lay the plywood inside the skeleton structure. For getting the smooth finish on the surface plywood will be covered with mica sheets.
Day 3As expected making the templates was completed today. As ply wood alone will not be strong enough to keep the shape of the hull, the templates are to be strengthened with wood (refer to the pictures). Also these templates are joined to the keel structure by joining these wood members and the keel structure using nails.
Day 4Keel structure is prepared using the keel offsets. These offsets are marked on the plywood. Then wooden pieces are joined(refer to the picture) to form the bottom shape of the hull. Then the keel structure is kept in the vertical position, so that the templates can be fixed on to it. Make sure that the plane of the templates are perpendicular to the |
