I figure that having an essential part of your boat out there in the 
open where it can easily get caught on other boats, floating 
tree-trunks, etc, would be a disadvantage, especially if these boats are 
made for navigation in crowded waters, as Dr. John mentions.

Also, I've sailed boats from 3m-long Optimists, to 50m long sea-going 
cats that had no problem with the gaping hole in the middle of the hull. ;)
