I recently bought a 94 H26. I am about 5'9" in my bare feet and I cannot stand up straight unless I spread my feet out & stand under the sliding hatch. My 5' wife can jump up & down in there.It is enough that I do not usually bother to raise the pop top.That said, it beats the heck out of my last boat, a MacGregor 25, that only had standing headroom under the pop top.
