"he has not indicated any habit or ability around an on-water re-entry. Your posit that he has an on-water option is not something I can see a basis for here."
When you can stand up, there's no need for any "technique", aka ability, for re-entry! Just stradle the boat and get in!!!
Besides, it doesn't really matter. If the re-entry doesn't happen, just swim or wade ashore.
That's my whole point: all the crap people throw around doesn't apply in this case!
"As I found out, the time to be unable to help myself can be under 5 minutes.
Your personal experience when you were younger is not necessarily going to apply for this individual"
By the same token, nor does your personal experience necessarily apply to this individual either!
The OP should try his "rescue options" himself. Simple as that.
