Live Aboard and Travel with Parkinson’s Disease

Here is possibly a whole new and different question for everyone out there…
Has anyone ever been a “Live Aboard” traveled to different places or maybe even did the loop and had say… Parkinson’s Disease?
I see everyone chat about everything under the sun but what about those who love boating or fishing and have this disease. I’m talking motor boat not sailing. Just curious if anyone has or is currently a live aboard with such a disease and how do you handle it on a daily basis.
Yes I have Parkinson’s and yes I miss the water very much. The ocean, the icw are in my veins. Nobody would understand this but other avid brothers and sisters that feel the same way.
I figured if I got a sportfish I would need a swim platform and transom door to get on and off. If I got a motor yacht I would need to purchase stairs to get on up on the side of the boat. Or if push came to shove purchase or have made a folding ramp instead of stairs. I’m still able to walk and drive. I’m not dead yet. My Parkinson’s has not progressed to the point such as Michael J Fox. I have other symptoms of the disease.
Please give me your thoughts. I could really use some advice about now!
