Depends on what you are doing with your boat at the end of the day. Mooring - slight increase in risk of taking on water but nothing to worry about without wind or big rollers. Lift is probably OK as long as lift can support extra weight - but you could stress your hull with the extra weight being dispersed on the small surface area of bunks. Trailering bad all the way around: bad for your trailer, bad for your tow vehicle, bad for your boat - more weight now bouncing around on small surface area bunks.
Edit: I didn't see your last post Montgomey.
