Jacques,
I'm talking with a builder about ballast (may not may not be Bogieman) and we started thinking about lead alternatives. Since we there is a need to fill a large area under deck, is there a reason encased steel, iron or concrete can not be used?
Thanks.

Lead has a specific gravity of over 11; steel about 8; concrete about 2. 4. You're going to need a lot more space for those materials.

If price isn't a concern, tungsten.

Re: AD and VG ballast options
Price and availability are the issue.
Lead is more expensive to acquire than steel thanks to EPA and other regs. Steel if highly variable and difficult to form. Concrete is simple but as T said you need a lot. From my minor conversations there should be enough space to accomplish the job with concrete. “Should be”.
I just want to make sure that there’s no issue with the slightly higher/wider profile that would be generated by filling with non lead ballast.

I always though that the weight being in the keel/centerboard did more than just add ballast. Thought that it also gives leverage for when the wind tries to blow the boat over.

Re: AD and VG ballast options
100 pounds in the bottom of the hull doesn't have the same effects as 100 pounds hanging 3 feet below the bottom of the hull. More noticeable when the wind blows the sail. It's like a lever and a fulcrum. The hull is the fulcrum and the keel is the lever. 100 pounds in the hull with a light weight 3 foot keel would not have the same effect on a boat as a 100 pounds at the end of that 3 foot keel.

Re: AD and VG ballast options
Ok...
There’s the CB lead and the hull ballast. The CB is not the question. It is the ballast (which is static in placement) that is under question. If one does the CB ballast properly (with lead) you still need 150lbs which for around the CB trunk. That’s only 2 bags of quickcrete which will fit in there nicely.
To reiterate the only portion in question is the static ballast intended to be installed around the CB trunk.

That ballast would be located forward of the trunk in the Adelie's.Jaysen wrote: ↑Wed Jan 30, 2019 6:50 pm Ok...
