I have a 07 275 XL. I was looking at the underside of the hull and noticed that the silicone caulking that goes under the rubrail - where it joins the hull has 2 gaps in it. One on either side of the bow. I don't have a picture of it yet but the caulking starts at the tip of the bow, goes for about a foot on both sides, then the 2 gaps, then caulking resumes all around the boat.
Is this by design?
