Ferry boat

[TANSL]

Given the high number of passengers it may be interesting to consider a catamaran, less than 24 in length (which can be a LOA> 24 m). Being a semi-displacement boat, catamaran could be advantageous, for space and stability.
You should do as soon as possible an estimate of weights and centers of gravity, as well as center of buoyancy, to determine if the forward volume is enough or it is not.
But I think the first thing at this time is to check that there is enough space for all passengers, ship equipment and its services.

Nishan, contrary to what many might believe, the NA always start from a known forms of boat, a 3D model Rhino, or a body lines plan of a similar boat. I do not know anyone who has invented from scratch, without having in mind previous projects, shapes of his design. The spiral of the project allows to adapt the initial forms to the final of the current project. Even it is very normal to start with a SOR of an existing ship.

Is it really that information (professional qualification) what we need to know at this time to answer OP's questions?
In this forum there are many members who, not being NA, have very clear concepts on naval architecture and shipbuilding and say interesting things that everyone, including NA, respect. So my opinion, and I respect other opinions, is that the title one person could have does not need to be decisive. Why is it necessary to know the titles of a person ?. We can analyze and evaluate his comments without knowing anything about all that. Do not you think so? . Have not you ever read something wrong written by a NA?.

Back to OP's questions, seems this hull can give a large initial stability (initial GMt) though, as for any passenger ship, should study the passage to a band, the damage stability and many other things (necessary studies in the later stages of the project). Speed also be decisive in the shapes. It does not seem that this hull is the most suitable for high speeds. We need to have more data. OP should propose a SOR and GA drawing to give a more correct opinion.

Greetings with respect to everybody, NA and non-NA. I, at least, will judge you for your comments, never for your titles.

Thank you for the opinion about the design. Yet I'm to edit the lines on rhino. this is a very initial stage hydrostatics. The photos show some more info.


Agree with you about the title issue. what matters most is what one says. I told about the qualification as an answer to a question there. Hope my comments weren't offensive, but yeah I was defensive at some point here.
I really respect the the experienced members who make long stories really short. One reason why I here is to learn from the experienced members.

Thank you TANSL! A time saver you are!

Hi Nishan, I have experience in design of GRP passenger ships between 15 and 24m. If you think I can be useful in something do not hesitate to contact me.
Cheers.

Why not a catamaran ? All the rage for such work these days.

 

[Nisham]

Yeah time for a catamaran I guess. At production capacity checks now.

Hi.Have designed many commercial ferries etc.
why would you not consider a catamaran-multihull, can usually accommodate the numbers and require less horsepower especially on short runs. more stable and passenger friendly.

Gut feeling here owning a 20-meter boat, it is hard to fit that many people, all the safety equipment and make it comfortable even for a 15-minute trip, then of course, we have laws and center of gravity issues. Sounds like you need a much bigger boat. 30 meters

Thank you all for the replies. Advises considered!
