Grażyna

Grażyna
Grazyna-shipGrażyna [ɡraˈʐɨna] is a Polish feminine given name. The name was created by the Polish poet Adam Mickiewicz for the main character of his 1823 poem Grażyna. The name is derived from the Lithuanian adjective gražus, meaning “pretty”, “beautiful”

Built as M/S Schilksee in 1927 in Germany by Howaldtswerke AG. The dimensions of the ship were ~ 100 X 23 X 7 feet. She carried a 6 cylinder diesel engine and had a top speed of 10 knots. She had a capacity of 130 passengers. The Soviets used her during WWII, named “Uranium”. She then served under Poland with the name “Grazyna”.

Grazyna_01_1200This would be a pretty good size for an O scale layout. In 1:48 the ship would be ~ 25 x 5-3/4 x 1-3/4 inches. That last dimension can be ignored since I would build it as a waterline model.
Beauty
Since the idea is for a small ship that would preferable carry cargo instead of just passengers – as pretty as she is I think she needs modification. The size is right though for a starting point. Since Grażyna translates as “pretty” or “beautiful” .. I’ll name my version “beauty” .. at least for now.
Mod_1Mod 1 – I shortened the cabin by about half. I suppose this could represent a dual purpose craft carrying both passengers and cargo.
Mod_2Mod 2 – Here I moved it way forward. This would leave room for a large cargo hatch(s) at the rear. It would need a cargo boom I think .. possibly move that mast back for that .. which would make sense.
Mod_3Mod 3 – Finally, I used the shortened cabin and moved t0 to the rear.
I readily admit I know nothing of ships. If and when I get to the deck the ‘plan’ will have to be of course modified by further research and people who DO know boats telling me what to fix. It seems to me for example that all those stays from the mast would interfere with moving cargo. Shrug.
Waterline
CheckWaterlineI put the ship cross-section next to a side view and leveled them to confirm my guess that what is labeled W4 in the diagram is the water line of the ship.

This gives me enough information to start by creating the frames from the cross-section, slicing them off at the water line.

Keel and framing
ModelSetupI brought the graphics into Sketchup to create a mesh that I could manipulate easier. I cut the framing off at the waterline. I still need to “get a handle” on the prow as I think .. I may need to re-think that .. but this is a good start. Which ever way I go .. if I add cargo hatches I imagine that part of the deck probably needs to be flatter – maybe .. so need to do some research there.

Note that I have one measurement – the Keel works out to 2.613 in. In O scale that is 0.054 in. .. so 1/16 in stock would work for that. The framing will be .. whatever .. since that won’t show.

I got to thinking .. I need to see what I can use for the Keel. It measures just a little over 31 in. x just under 3-1/2 in. .. so before I go any further I need to see if I can locate stock that size that is 1/16 in. thick. If not need to see what I CAN find. Honestly it can be thicker then that – just the bit at the very front that shows would have to be to scale.

BALSA USA – has it in 1/16 x 6 x 48 – 3 ply and 1/8 x 6 x 48 – 5 ply Birch Aircraft Plywood. Since the only thing that will show is .. as I said .. the front end of the keel so it would make sense to go with the 1/8 in. plywood simply for the added strength.

working_1Making stuff fit. Despite my best efforts, for some reason the bulkheads ended up taller than the keel they slot into. Shrug. Since I normally don’t allow reality to bother me too much I scaled the bulkheads to fit the keel. That will give the ship a lower profile which is fine with me. In any case, once I get the keel/bulkheads all done I will need to actually look at some model boat links to see what I am missing/need to change/add. The Stem needs to be rabbited so the planking fits nicely, adding the gunwhale .. that sort of thing.
Version 2 – or 3 .. I forget
ModelI finally figured I was looking at the wrong line for the deck (insert .. duh) and re-worked it again .. and then again. Pretty much ok with this version.
Model2Working on the deck .. the sheet compounded/compounds the working.
Assembling
assemble_2Starting to cut the bulkheads out and rough-assemble them to the keel. Since this is a waterline model the bulkheads will sit flat against the surface which means that with them slotted over the keel and flush against that surface I can finalize sanding the tops .. using that surface as a level point to measure back up to. The same time I will adjust the sheer of the keel to match the horizontal surface of the bulkheads.

I have been using my scroll saw for this. It works – but I can see where a smaller, modeling sized scroll saw would work better as this can be some finicky cutting.

assemble_3We were talking about this build in the Whistle Post Chat. There was some doubt cast as to how well I can plank the stern. I find myself a bit mullish .. thinking that YES .. I CAN plank it dang it.
Framing roughed in
assemble_5Frame roughed in. Do some tweaking tomorrow and start gluing it up.

  1. Ed, love the blog format. You have a great bunch of content I wasn’t aware of here. Look forward to a collaboration. The way you moved and sized the cabin is just so easy with sketch up I bet?

    • The side view? I just did that in Paint Shop Pro to give me a general idea. I liked the size and shape of the hull but wanted something more like small a tramp steamer – just wanted to get a feeling on how to put the cabin.

      Look at Part II where I will start working on the design of the superstructure more.

  2. One thing you have to watch out for on a blog is too much info on one page .. it becomes something of a hassle to scroll down (JMO) .. so that’s the *why* of multiple pages.

    • I found a really cool little ramp/elevator thing for a dock. Now .. if I can only find it again!

      Edit: Called a Wharf Drop. Something like this would be cool to model .. even if not as useful as a gangway. It was in “Wharves and piers: their design, construction, and equipment” .. one of those Google Books I was talking about.
