Only problem with that is, 200 years won't get us anywhere. When talking about generation ships traveling between stars, we're talking about 2000 years - anything that big would be far, far to massive to accelerate to any appreciable degree of C. Which then means that genetic drift becomes a serious issue. Never minding linguistic drift. What happens when the crew can no longer read their technical manuals or labels on the reactor?
Although, to be fair, insects as a source of protein would likely be the easiest way to go.
Well why would they no longer be able to read their manuals and labels if every generation has to do read them? The language drift shouldn't be a big deal if they constantly have to use the "original" language. At least no the written language. The spoken might differ more strongly.
