The REAL question is you still going solo again?

That Dry-fly I keep telling you about would fix those first two issues and when the wind is to fierce you wouldn't be on the water tandem either.

My dryer lint/paraffin wax Magic candle DIY fire starters would take care of your wet wood problem.

A pair of rag wool gloves while paddling will fix the blue finger nails.

You’re on your own with the huge field knife, putting a hole in your canoe and vomiting from either sea- sickness or food poisoning. :o :-/

I find a warm hot chocolate /coffee laced with some booze around a campfire at night makes most of those concerns just part and parcel of a good trip report. ;) ;D ;D
