Where to buy 3D sea maps?

Or land maps for that matter?

I caught the v tail end of some part of 'Nationwide' a few days ago, there was a guy on who I think creates 3d maps etc.

Its for a gift, so the standard OS flat maps are not what I'm looking for here.

Any suggestions? Its for someone who is an avid sailor and also hill walker so the more detail the better.

Thanks!

Sorry this is a bit late but only saw the thread today.
Saw these at a boat exhibition in the RDS and was very impressed. Not cheap, but very professional looking.
