CD 270 Headroom & Grounding characteristics?

[rwi4]

I'm trying to compare certain features of two boats- the CD28 & CD270. Does anyone know the exact cabin headroom of a CD270?

I like the 'shoal draft' concept for shallow waters and real sheltered anchorages. I'm wondering what it's like to go completely aground (intentionally or unintentionally). Will anyone confess to doing that? Does the boat heel over dramatically or not? Also, what's it like for a CD28 to go aground?

Much Appreciated,
Richard
