Sailing 2 weeks ago and my mast well broke loose top and bottom. When I looked inside the hull (have some ports in already) it looked like a piece was still there and it had split in the middle. Then to night I look a little closer and see the well doesn't go all the way to the bottom of the hull, seems to be raised (or filled???) about 3 inches. Is this normal? Pix attached, the tube part that remains is solid. Thanks, Winever.
