Why the funnel in the extreme bow?

It's an Ramform hull.

almost all Ramform hull ships have there machinery in the front.

for example this one. look how far forward and up in the hull those diesel generators are placed!

and guess what advantage you get with that hull.

an ramform vessel of that size is likely to run out of usable building and docking sites, let alone ports...... I might be wrong, but weren't all ramform ships about half that length?

Post subject:  Re: Haram Reramp
the biggest build to now is "Ramform Titan" she is 104,2 meter long and 70 meter wide. what I did was cut of 10 meter on the width and added around 28 meter on the length.


That people think an Ramform hull need special ports, are wrong. they just park like any other vessels. in some harbors they will be allowed to use anchor to assist. but most ports only needs and big round ball with many tires on placed around center of the hull length to help.

Here is an port designed for an Ramform, not how little pier it needs. it only need that one aft, and an something for the mooring in front. so instead of an big massive pier, two small one:

at normal ports, note on some of them a floating ball with tires on, many of the old Ramform ships had those with them, but today all normal ports in the world have some laying around, for example when mooring an submarine:

hers an picture showing how special the form of the underwater hull of an Ramform is. those reminds me that I probably need some light shading on the underwater hull to show that hull shape:

btw. I remember once up in Tromso (a city North in Norway) my step dad was the weekend officer on duty, he had command of the biggest naval base in North Norway, where more than 60-70% of the base is under ground in an Nuclear protected area! one of the day the Norwegian Research ship (spy-ship) FS Marjata come in to the base for stockpiling and refueling (doesn't happen often!), and that day an US submarine was in for getting food (US submarine on patrol in the North sea/Atlantic, could drive in there under cover) and one Oslo class frigate. so there wasn't much space. so what the captain on Marjata did, instead trying to get the ship in that tight spot, he just parked with the rear end in. (apparently the captain shall have said: "Why not!").

Very unorthodox, yet interesting idea, but great work with the drawings.

if you lower the relative beam, is it still an true ramform ship?

yes! A Ramfrom is not about that the ship must hold a specific beam ratio.

MS Ramform Sterling: "L X B:102,2 meter X 40 meter" 2,705
MS Ramform Titan: "L X B: 104,2 meter X 70 meter" 1,488
FS Marjata: "L X B: 81,5 meter X 39,9 meter" 2,042
wally + Hermes Yacht "Ramform": "L X B: 58 meter X 38 meter" 1,526

my Ramform hull: "L x B: 134,46 meter X 60 meter" 2,291

Nice drawing! Will you be doing a top view too?
Author:  heuhen [ February 8th, 2014, 12:05 pm ]
Post subject:  Re: Haram Reramp
perhaps later on, the problem with a hull with so much space is to use the space as best as possible. many problems I would have to find out when drawing the top view is:
how big is the under deck hangar?
are the bellow deck weapon a part of the Hangar or not?
how much of the ship is going to and what area shall be assigned for weapon testing and radar?
