The area where the illegible writing is, is circumscribed by a solid line. There is a vertical line just about a foot aft of station 5 and a horizontal line leading forward from the top of that vertical line all the way to the profile line. It intersects the profile just under the bulkhead at the forward end of the settees.
This inscribed area is where your 3,000 lbs of lead is. That is the ballast keel. You will note that the
compression post for the
mast is stepped off on top of this slug of lead. There are sound engineering reasons for doing things this way.
Dollars to doughnuts that if you tap the bottom of the bilge at station 5 it will sound solid rather than hollow.
If you
work the volume of the space using the drawing as a guide for taking measurements in the boat you will know whether you've got lead or cast iron for ballast. SailboatData sez the boat has 3K lbs of ballast. Lead weighs 708 lbs per cubic foot, cast Iron about 450 lbs. Therefore 3K lbs of lead will take up a space of 4 1/4 cubic feet. 3K lbs of cast iron will take up a space of 6 2/3 cubic feet.
We can't tell from the drawing if the slug is encapsulated or "bolt on". If you don't see bolts and nuts at the bottom of your bilge, the slug will be encapsulated. Either way, there is no room there for tankage.
