I have often enjoyed boating holidays but thought I may have to give up after being prescribed oxygen. Up to 9l/min when exercising and 2l/min at rest.
Of course not many boats could run a concentrator at such a high flow.
After a disastrous encounter with Broom Boats in Norfolk who (even though I had advised them 3 months in advance I was having oxygen cylinders delivered) they refused to allow the oxygen delivery and cancelled my holiday also refused a refund. Even though a large part of the costs were fuel, insurance and cleaning.
After ringing around, Barnes Brinkcraft came to the rescue and had a boat ready the next day. BOC pulled out all the stops and delivered to the new boatyard the next day. We were given a very warm welcome by Matthew and his team at Barnes Brinkcraft. So I had 20 bottles on board for when off the boat and my Inogen 1 5l pulse flow for when sitting on the boat. The Inogen uses very little power and a charge lasts 5 hours.
So, don’t think it’s impossible. Barnes Brinkcraft are the go to people. They have wonderful craft as long as your mobility is ok. They’re not wheelchair friendly but I doubt if any self drive boats are. I did take my efoldi scooter but didn’t use it much as the terrain is so flat.
