I share this With Dr. Shukui Liu who has maybe the best overview on this issue.

Shukui Liu

Thank you both for inviting me to respond this question!

I am afraid I shall disappoint you as in my work I focused on cargo ships only thus do not dispose much information for multi-hull forms.

As far as I remember, Prof. Huijsmans' group has some work dedicated to fast ships. Perhaps you can turn to his publications to trace something useful:

Good luck!

Ardhana Wicaksono

You may check the PhD thesis of Prof. Eko Budi Djatmiko (Hydro-structural studies on swath type vessels). Even though the study does not cover the added resistance experiment and calculation, the author provides us with the geometry, test conditions, as well as computed and measured motions and wave loads.

Hope that helps.

Zhiyuan Pan

Thanks! I will take a look. I got hold of the test data from Marin in an earlier CRS project. :)

Aleksander Kondratenko

If this question is still actual, I could recommend you to contact directly with this expert on the topic of multihull vessels. He has long-lasting experience in the mentioned field.

Victor Dubrovsky

Usually multi-hulls have hulls of big enough elongation. It means decreased added resistance in waves ion a comparison with corresponded mono-hulls. Added resistance in waves can be defined by the same methods, as the same characteristics of mono-hulls.

Besides, the real speed at sea depends in main from speed restrictions and - or from heading changing for ensuring of the permissible characteristics of seaworthiness. Added resistance restricts speed only if the waves are small enough.

Victor Dubrovsky Aleksander Kondratenko Thanks for your input, I have got the permission to use the experiment data from MARIN for my study.

Leo Lazauskas

I would start with this very recent paper.

Trimaran motions and Added Resistance of two configurations of a trimaran,

International Conference of Ships and Offshore structures 2019,

Nov 2019.

Also refer to the research papers for one of the co-authors (and Research Gate member) Michael R. Davis.

Leo Lazauskas Thanks for your comments. Could you share a link to the conference report, which includes your work on added resistance, if it is already open to the public?
