Having been involved in a slam which resulted in water
coming into a quarter berth through an open overhead hatch
under the dodger, everything gets closed off. The one exception on the C&C
44 is the weatherboard, the hatch
gets closed but the space for the weatherboard is only about 4 inches. On other boats, the weatherboards are installed. Broad reaching can involve getting pooped. An acquaintance was on Delicate Balance which had to pull out of Vic Maui in 2010 after getting everything soaked.
The dorades get sealed, to prevent water from getting in and prevent lines from snagging.
