I own and sail a 1984 Catalina 30 in a large freshwater lake in MS. Because there are no facilities other than hiring a large and very expensive crane to pull boats, larger boats tend to stay in the water a long time between hauls. My boat has been in the water for 7 years. In preparation for pulling my boat next month I got under the hull to check it out. The hull feels fine except for the expected slime, but I did find an indention, approx. 14" round, in the starboard rear quarter of the hull. It feels to be maybe 3/4" deflection. I'm reading that this is called oil canning, and can be caused by poor placement of jack stands, or occasionally by sling placement when lifting.
It's been this way for 7 years with no problems. I had never noticed any problem in the boats interior. So my question; how serious is this, and can it be repaired?
