keel weight question

[linejack]

I have a cold molded, lyle hess designed 20 ft sailboat built in 1985 by homan boats. It has an 8 foot beam, full keel with swept back fore on the keel. It is an Itchen Ferry design.
It was designed with 1200 lbs of lead keel weight bolted on slightly forward of center. There is an added 350 lbs of lead bolted down in the bilge just aft of center. I do not know if this was added by the boat builder or added latter.
When I loaded the boat on a trailer it is obvious that the center of gravity for the boat is well aft of the center of the boat. Without the added 350 lbs in the bilge the center of gravity would be at the center line of the boat.
The total weight of the boat is 5000 lbs. Should I move the internal ballast forward? What is the average acceptable ballast for a cruising boat 18 feet at water line, 8 foot beam, 5000 dispacement, 250 ft of sail cutter rigged with 4 foot bow sprit and full keel.
I do not race and do not care in the least about speed. The boat is very aft heavy especially with the 9.9 outboard motor. The trailer is twin axel set up for the boat to be center balanced.

The weight needs to balanced relative to the fore-aft center of bouyancy while afloat. Launch her before messing with the ballast. You can usually move the whole boat on the trailer to affect balance.
Sounds like a great boat. Must be beautiful.
