I know the westsail 32 has 35%, and the Tartan 3400 has 55%!

So my question is if you were going to make a blue water passage or circumnavigate what would you want your bal./disp. % to be?
Be careful what you read. Sailboat Data has a few mistakes

Ballast ratio is but one factor of stability. Where the ballast is and what it is composed of have an effect as well. For example the Pogo 10.50 looks from the numbers to be under ballasted at 30%, but its ballast is in a bulb with a depth
of over 9'. As far as material, lead is more concentrated for its weight than iron so all else being equal a boat with lead ballast will have more stability than the one with iron.
