You need to take a close look at the hull area just above the keel stub for spider cracks and fractures in the fiberglass. Both the forward and aft ends above the stub. This is usually where the most damage is done because the stub is pulled down at the leading edge, and compressed at the trailing edge, on impact. While the keel itself may only have some minor cosmetic damage. Also look at same areas in the bilge. This of course all depends on how fast you were going when you hit the rock.
Hi Don,
You mean where the stub meets the hull… correct ? Since this would be visible from both inside and outside. Probably where the glass starts to get thinner?
So far I haven’t found any damage to the hull or stub. Will continue looking.
Rob,
Yes, see red circled areas in attached photo. If you were going 5 knots and hit a rock, did you come to a sudden dead stop? Anyone standing up would likely have fallen over. If so, I’d be surprised that there wasn’t more damage than a nick in the lower keel. However if it was just a glancing blow without the boat stopping, you might have gotten off lucky.
Don
