I was thinking how fun it would be to have a ROV
camera. I looked up the VideoRay - too $$$$. Then I stumbled on this guy who built his own using six Attwood
bilge pumps as thrusters. Now that's impressive! Watch his
movie....

As to the
keel. The other risk (but small) is that you broke a
keel bolt. Usually a forward one. Unfortunately, the only sure test is to drop the keel which is really expensive. As said, everyone runs aground. If you don't see any sign of cracking or "working" in the
bilge - especially under sail - you're likely to just have a gouge in the lead that needs to be faired next haul. One reason to haul now is if you want to consider an
insurance claim.
