Hi Peter,
Awesome idea and it got me thinking ( well actually googeling). I remembered a video clip of how a Charlie Chaplin ( pretty sure it was) scene was shot on a boat. Couldn't find it but here are some modern day ideas.
Obviously you need the cam to be as still as possible. So some sort of gimble/ steadycam rig is needed.
Here are a couple of links I quickly googled ( after failing the Charlie vid)

Even if the video/timelapse is a bit wonky, I believe there are programs out there that can center an object and rework it. Like if taking a vid or shots of say Jupiter is all over the place the software will center it post processing. ( From memory I think JJJ posted a long time ago about this.... I cant find it now)
Hope this helps and gives you some ideas......
Cheers and have an awesome trip ( well when you go of course......next year)
