I don’t actually need the chair on board, I’m just worried about them seeing me arrive in it…Call dive-charters ahead of time, and explain your situation. See if they're okay with that.
I'm not an operator myself, but if I received such a call, I'd have a few questions. "How much diving experience do you have? How many dives in the last year? What kind of assistance do you require?" If you have a bunch of recent dive-experience, and don't require an extraordinary amount of assistance, I'd maybe be okay with that. It may also depend on the conditions as well, for example, I'd perhaps have some safety concerns if there was a current.
Whether the charter/shop/operator would be okay with that is another matter. You could be turned down over legitimate safety or liability concerns. They may simply not be able to offer the assistance you require. They may lack space or ramps for a wheelchair. They may also be ignorant, and reject you for ignorant reasons.
And if one rejects you, call the next on the list. That said, try to get CONFIRMATION, perhaps even written confirmation (an email, text-message, etc).
Good point about getting written confirmation!
