I just went on a sea trail on 2000 259 convincor and mechancially everything seem ok. Upon looking around the engine compartment i noticed an open seam in fiberglass on top of the stringer. The marina state that its not structural just where the fiberglass mesh overlapes and is just done as a finish for appearnace. The port side overlap runs the lenght of the stringer as far as i can see untill it disappears under the floor. The starboard side finished a little different but still has fiberglass overlaping with some peeling apart. Any ideas?
