Inclining Experiment For Catamaran

naserrishehri, dear friend, despite my mistake in the first post, I still believe that I can opine and try to help. I will explain an opinion and hope nobody thinks I talk excatedra, I am not in possession of the truth, I will not be dogmatic.
The inclining test catamaran is tough and has little accuracy, unless it is done taking heavy security for data capture. In your boat practically no space to place the weights and, what is worse, the offset distance of the weights can not be great. It seems to have more space aft Main deck and Bridge Deck, which will cause, by placing weights in these areas for the test, the trim of the boat to be higher than desirable. All this makes the results of the inclining test may be very questionable.
I'd try to talk to the competent verification body trying to find an alternative method, as is done in boats subject to the ISO standard, which could be, for example, a, comprehensive, detailed calculation of the weights and c. of g. [See method c) in Alik's post #14]

 

The demi-hulls appear quite wide and the 'cat' may almost behave as like a monohull of barge hull form.
Those 'protrudenses' would make coming alongside 'interesting'.

 

Out of personal curiosity and off topic (excuse me for that); I notice arrangement for protruding waterjet inlets. This is normally used in connection with foils; in this case the nacelles are just increasing the draft and resistance. What is the purpose?

 

Good point Baekmo, I noticed that as well but after looking at the hull form, hull/hull clearance, etc, I figured the max speed would be about 10 knots so it might not make much difference anyway.... until it hits a rock.
ps: not sure where the navigation station is... the for'd end of the bridge deck is fitted with what appears to be a small casino. There are also many other anomalies which will raise the stakes.

 

dear baeckmo
you are right. this vessel was already a hydrofoil. after cutting 2.7M under water part , the vessel's shape changed to this new GA.
