Thank You Caravan and welcome to the Forum.
Many boaters have to make special arrangements so they can take part in their beloved hobby. (Fiona demonstrated with courage, energy and enthusiasm that boating and an ileostomy can go together brilliantly. Others have shared their stories in private.)
The real job is educating people around them, around all of us, around children with ileostomies or any other special arrangements. Ignorance is a huge barrier but one that can be overcome. We're all in the same boat at the end of the day.
