I had understood it was not a problem if your single through-hull is not
bonded to anything else. What size/type of capacitors do you recommend?

Well, that is a large counterpoise and I'm sure it works fine.
However, depending on the ground arrangement through your radio, it may be a
recipe for dangerous electrolysis. The connection to the thru-hull should
be done with RF capacitors that will block direct current.
