Great bit of writing Emma! But, of course, you are dealing with temperatures that are always somewhere between deliciously pleasant and a tad uncomfortably warm. Still, it is amazing how the desire for a bath can outweigh one's dislike of cold water
when traveling out of the tropics. As far as relieving oneself, urine is sterile, unless you have a UTI, and a saline solution, so not much danger
of polluting the ocean there. Hang on, one hand for you an one for the boat at all times!
