I am thinking about buying a 1973 Laser. The boat is in good shape except there are two softer spots (not real soft). One on each side of the cockpit on the deck near the inner edge of the cockpit. There are also 2 hairline cracks along the edge of the cockpit. When I press my thumb down on these spots I can depress the deck maybe a quarter of an inch and it makes a scrunchy noise. Is this a serious issue; can this be repaired and should I buy this boat? Thanks Bill
