R C Cruise ship ???
I was wondering if anyone has made a large scale R C cruise ship like
Royal Carribean new ship "Oasis of the seas" its in real life 'when its launched is 1,184 foot long and has a beam of 154 foot wide ,how do you figure scale size ?? so its about 8 to 10 foot long ??? I havent got a clue as to how to begin building this ship, or how and what materials I would use ,and what costs to expect , Has anyone used bluecore foam on this types of project Can any one help me with some info thanks

It sticks in my mind, because as he sailed it around the pond, there was conga music coming off the decks.. 




To figure scale you just divide the actual length of the ship (1184 feet) by the desired length (8 ft) and you get a scale of 1:148. Unfortunately that is not a standard scale, however 1:144 is which would make your model 8.2 ft. long (1184/144).
1:96 scale would give you a model 12.3 ft. long...

J, I'm not a math major, so I'm probably not the person who needs to reply to your post, but let's see what we can figure out here, with the aid of a handy dandy calculator.
You say that the prototype ship is 1,184 feet long. If you multiply 1,184 times 12, you obtain the number 14, 208, or the ship's length in inches. This is your key number in the calculations that you want to do. You mention a possible model length of 8 feet. Alright, 8 times 12 inches is 96 inches. If you divide 96 inches into 14, 208 inches, you arrive at a scale of 1/148. This means that one foot on your model is equal to 148 feet on the real ship. That scale is a bit awkward to work with. If we divide 150 into 14, 208 we arrive at a model length of 94.72 (inches) or 7 feet 10.72 inches. This model would have a scale of 1/150, of course. A couple more examples. If we divide 160 into 14, 208 we arrive at a model length of 88.8 inches or 7 feet 4.8 inches. For a model length of 10 feet or 120 inches, we divide 14, 208 by 120 to get a scale of 1/118.4 . I hope this hasn't been too tedious for you. Keep us posted on what you decide to do. Bill 



I hate to be a bubble breaker, but if you don't know how a shaft exits a hull, a 100" long, 165 pound model would be a monumental project.
If you have an interest in cruise ships, and like to scratch build, try a smaller scale first. Say something like 1:350. That would put you at 40" and 11 pounds. Construction could be plank on frame or carved foam with glass. The challenges will be to design the drive line, as the Oasis uses a pair of azipods in back and a bank of bow thrusters up front. Dave PS: A fixed drive system uses a tube fixed to the hull, filled with oil or grease, that allows the shaft to spin while preventing water from entering the hull.

After several of us pointed out the amount of work involved and the design / building challenges he would face, he revised his first model ideas and went a lot smaller. http://www.rcgroups.com/forums/showt...rnival+destiny Its not RC, but it gave Tugboater some idea of the challenges he would of faced with a large model. I have to agree with Boater_Dave, start smaller and then if that model comes out right, go for the bigger model. You will learn a lot along the way that will help you with the bigger model. 




Here's one that I'm restoring now. Scratch built in the early 80's by a fellow club member who has sinced passed away. It's standoff scale, stand way off scale. 61 inches long, weighs about 45 lbs.

Umi, there was a modeler from BC that built one or two cruise ships with music and lighting, large models. I can't remember his last name but maybe Keith S. could chime in here. I looked for some photos but only have video. Jerryj98501

This is not a "cruise ship" but is a model of a 220' mosquito boat fleet that plied the Puget Sound in the 1920's. It was the fastest ship of its size in that period and cruised from Tacoma to Seattle daily. The model was built by Jim Elder and will show the size of a cruise ship in the nine to ten foot size. The model is now in the Tacoma Maritime Museum in Tacoma. Jerryj98501

Thanks guys for your suggestions I was only thinking a model about
8 foot or so i don't want to go overboard....lol... excuse my joke I am in the thinking stage right now trying to find out all i can . My intrest is in "newer Cruise ships". I think I will try somthing smaller first and see what I learn for all of you on here ( if you want to share info ) about the power systems, Can you use my servos and motor from my airplane or is somthing different that runs it ?? and other question where on earth do you get plans for a new ship thats not even in service yet? thanks for your intrest in my project Jim 



Friends in the industry, and signed NonDisclosure Agreements are the best
way to get plans for ship that are not yet in service. The next best method is line drawings and General arrangement PDFs that have been published for publicity and sales. Then those have to be manipulated, and your frame drawings have to be extrapolated from the available information.
