Dead head

Well, your biggest concerns at this point would be if the dead head bounced off one of the through hulls or hit part of the drive train. It's easy enough to check the through hulls from inside and at least give yourself comfort that they're relatively secure. If you run the engine you should be able to see whether or not there's any new odd vibration to check whether anything is grossly misaligned. Other than that, I don't think I'd worry much more. We've hit deadheads and luckily have only scraped off paint.Peter

Heavier than I thought!

The last time I was in Vancouver, the fellow sitting next to me at the marina pub was a logger. This subject came up and we did the calculations for an average length, average diameter, almost saturated log. I don't remember the figures, but I remember it was far heavier than I had ever imagined. If the prop turns without any new vibrations and the rudder turns freely and the bilge pump is not running extra cycles you survived. The up side is that at four knots you did not put as much energy into the battering ram as you would have at 6 knots. I know in a situation like this everything becomes a little surreal as you wait for the next impact, but how solid did it sound/feel?

You can expect blisters in the area of

contact. If you don't have a leak, you may be OK.
