I saw someone motor into a rock (the marina sill, in fact) at 3 kts once.
There was nothing "gentle" about it.

Seen it, too. A friend with a C&C 35 Mark whatever (race boat...won the
Queen's Cup and Admiral's Cup) went cruising and hit a rock "gently" in the
North Channel...C&C "smile" quickly ensued. Also, big C&C that used to be
at our former marina named "Hedon" hit the reefs off the BVI, came home
wearing a C&C "smile". Methinks would be a good thing to take a little
snorkle trip under the boat and see if it's grinning.
