As someone who has spent time suffering from sickness and not being able to head home because I wasn't well enough to paddle in the challenging winds, I feel for ya. I didn't have the skin related side effects and my friends were experienced outdoorsmen who made sure I was as comfortable as I could be, but my memories share your pain.

Although we didn't use it, a portable VHF radio is your friend.

With great power comes Awesome irresponsibility.
