The initial weight analysis and subsequent structural analysis will determine the thickness and type of materials to be employed in any design. The approximate figures above are guidelines to be reduced if possible, once the hull has been tested and stressed for loadings in various sea states.
Any naval architect will tell you that this is a significant challenge. If at all possible, we do not want to use composites, if by clever design we can use more cost effective materials. In this case aluminium in the preferred material because it is easy to form, weld and repair while at sea. Please note that our consortium is looking for additional risk sharing and collaborative partners for this project. We do not at this time have a supplier of aluminium sheet or welding consumables.

DEVELOPMENT MODEL WEIGHT ANALYSIS - EUREKA
The same procedure is used to determine the mass of a vessel whether it is a model or a full size ship. The following is a rough guide or starting point from which the actual hull parts and components are being weighed in as they are made, or sourced, etc. It is an interesting time, with one eye firmly on the scales. There have been some heart stopping moments already, needing double checking.
Our tests will mostly be conducted in fresh water which at 1 kg/liter means that our model must displace 17.26 liters when ballasted. As we are building hulls of different diameters, the targets change from one variation to another. See the wooden buck below used to validate the active outriggers.
* The title "autonomous" is open to interpretation and should first be defined. We are taking the view that an autonomous ship is one that could carry out a mission without humans onboard, if regulations so permitted.
