I have used a lot of I2C sensors earlier, but never used any kind of I2C extension. I believe that the I2C protocol can handle about 1 m cable.
Has anyone moved the IMU? what is the recommended way to connect it?
thanks

I would use a longer hdmi cord or display cable and mount the RPI. The reason for this is instead of having one cable flexing all your cables have to flex now. Or use a second RPI as a display and keep the server tucked away nice and safe.
ribbon cable is fine within reason if it does not flex much. I Believe their are systems to extend this distance.
I am curious about how well imu would work via a wireless connection. In my wireless windsensor I had a about 3 to 5 ms lag. That is at the top of the mast and the rpi was under the companion way. If the sensor is closer that could be reduced a bit maybe possible:}
