Tape a 16" single layer of plastic grocery bag to the right of the damaged chine. Brush epoxy resin on the plastic, lay down one 5" x 14" layer of fiberglass cloth, and brush on more resin. (You're making a "form").The hull surrounding the crack is solid, but there's a good amount of flex in the bottom directly under the crack (because there's nothing keeping it rigid to the side of the hull). What's the best way to repair this? Thoughts.....?
