We once put 400 lbs in a 9,000 lbs boat a 'bit aft' of what we guessed was center of floatation - it lowered the stern by 2" and raised the bow by a lot, boat appeared to be popping a wheelie. Why - Center of floatation was significantly foreward of our guess.
Clarification .... my use of "lines" was probably not strictly correct. I was really talking about balance fore and aft, so yes flotation is probably a better term to use.

I don't think hobby horsing is likely to be a major issue but as WDS says, get that weight distribution wrong and you will have her down in the stern which apart from any performance issues simply looks bad.

(Reality is most cruising boats of small to moderate size will inevitably be down on their lines.)
