Ericso 28-2 draft

[Sidnewport]

Question: Sailboatdata lists the standard draft of an Ericson 28-2 at 4 ft. My boat looks pretty standard, but the bottom of the keel to the waterline is closer to 6 ft. So is my boat nonstandard, of is Sailboatdata wrong?

5' 6" on mine. Which is standard. My manual shows that 4' is for the shoal keel.
