Bruises only.
My ex told me of some of her relatives at a wedding by the water. Heading backing back at night, they managed to hit a rock with what I’m assuming was a Boston Whaler type boat, 16’-23’, maybe.
Bruises only.>>. glad they are ok but charts, compass, running the bouys and logging your position even without GPS/Loran goes a long way to being safe at sea, with sun, moon and fog.
