Out of clear blue sky after a rough day of sailing i found many leaks in keel trunk , one leak aft of keel bolts (very small) its been glassed, the others are from keel lock down bolt to haul ive glassed from lock down bolts to haul but keel lock down bolt is leaking really good and it is more than just the threads leaking. Going to glass over lock down bolt. Pulled boat out of water and couldn't find any damage from under boat keel bolts where still tight ????? Any thoughts on this
