Catalina 25 hull cracks

[Cruisin30MKIII]

Folks. Friend has an 81 catalina 25 swing keel. This season when he pulled the boat out of the lake, he saw these cracks. Anyone have any ideas? Lookin for advise. No water found inside the boat. He claims he hasnt run aground and swing keel cable has not broken in the past.
Thanks

My daughter has a 1981 c25 swing keel. It has nothing like those cracks. Try the catalina Capri 25 association forum for more info.
