The shower

The fun-est part of life offshore is trying to take a shower. The shower itself is 2'x2', with a corner cutoff. The walls are made of some mysterious compound that retains a temperature of about -2c no matter how hot the water pouring on it is.
Add to this a moving/rolling-with-the-surf floor and a typical shower sounds like this:
dum-di-dum HA!!! dum-diHAA!! la-la-WOOO! Dum-di-DOH!! la-la-lHA!! dum-di-WAAA!!! tra-la-la-lHAAA!! tabarnak fuck this!!!!

There is a handle on the wall you're suppose to hold on to, not to swish all over the small space.. but how am I suppose to wash my hair with just one hand?!?!? This was SO designed by a guy with a receding hairline >:S
