Lagoon 420 ad - clearance?

[Redbull addict]

Hi,

I picked up a sailing magazine a couple of days ago and an ad for the Lagoon 420 caught my eye. What surprised me was the lack of clearance for the underside of the deck between the hulls. There is a center bulb that seems to take away a lot of the clearance. In the picture the water looks fairly still but perhaps it was altered in photoshop or the picture in general was touched up.

In either case the distance between the water and the underside was about a foot. From what I have read and my knowledge may be out of date, is that you want as much clearance as possible. So that waves don't hit the underside and make noise at night or in heavy weather may lift the boat instead of the hulls cutting through the water.

The section that I'm referring to was smooth and sculpted as if to manage the contact of the wave so perhaps my understanding of what's a detriment to multihull design is wrong.

Curious to hear others take on this.
