I was given the task to create a hull which must be propelled by human and solar power; I have found it difficult to obtain existing hull designs with their respective coefficient of total resistance so I am looking for a way to calculate the total hull resistance for a hull of my own.(adsbygoogle = window.adsbygoogle || []).push({});

I require the hull to be simple in geometry as I should propose a way to manufacture it at the least possible price. I was thinking about a circular cross section hull, as shown below, as I think it would be quite simple to manufacture. I am aware of the 1957 ITTC line but do not know how to extract more data from the model to get the total drag resistance. I am aiming at a speed of about 1.5 to 2.5 m/s.

Also, is there any simple method to calculate the extra power required to propel the hull in slightly rough seas?

Any help would be greatly appreciated.
