Not an easy question to answer
Only you know your ability and mobility.
There are small
boats which are purpose built for paraplegic sailors.
I would suggest, contacting a local
ASA school and going out for a sail with them to get a feel for it.
You don't need to be able to
single hand in the roaring forties to enjoy sailing.
For many of us its a team or group or
family activity done in sheltered waters in light to moderate conditions.
If sailing with friends even who have never sailed you can always explain what needs doing if you know the process.
Expect to be able to move about slowly and carefully on a boat to heeled 20 degrees and pitching a bit.
Much if not all of what you need to do can be done from within the
cockpit moving not to far on a modern
charter yacht. Except for going to the heads.
Some you don’t even need to go forward to stow the
mainsail. Just for tying up at the end of the day.
I used to take my dad sailing after he had a stroke and had quite significant difficulty walking and little strength on one side. He really enjoyed it
Give it a go, you won’t regret it.
