Looking at the photos posted by Owen above the Bridge Deck clearance looks OK ,the Centre part is low for standing
head room ,kind of like Richard Woods Romany with the nacelle about a foot and a bit off the
water but set back quite a ways from the bow so the boat rises with the wave and it's no problem in the Romany case the nacelle is also angled to deflect the striking wave.I am building an Eclipse 32.5' Woods Cat and the clearance looks similar to Eclipse which has pretty good clearance for a Bridge Deck Cat.

The part in the review about clearance that I found is below :
"very convincing in terms of performance, it must be remembered there is little
headroom under the net in spite of its 20-cm increase over its precursor, the Edel 33, which makes progression through rough or heavy seas quite labo- rious. This is the main drawback in our test, when compared to recent competi- tors, all of whose nets are higher on the
water."
