Hulls - Soft or Delaminated hulls on older boats
Soft hulls are caused by the foam and fiberglass layers becoming seperated or delaminated. This can be caused by heat, repeated compression (walking on) or other factors related to materials and age. This is normally correctable. A soft area is a structural breakdown and should be corrected before sailing the boat. Soft areas in decks near or ahead of the forward cross bar can cause complete failure of the bow and must be repaired before sailing the boat.
