Run Aground
To all:
I need 3 numbers from everyone:
First number = number of times you've run aground, or had major underwater impact(s).
Second number is to identify the belly of your boat: (1) bulb keel/ spade rudder, (2) fin keel skeg-hung rudder, (3) full keel rudder.
Third number is gross damage: (1) Heard a "bang" drove away/ cosmetic, (2) hit hard/ required repairs/ didn't sink, (3) major impact/ extensive and serious damage/ stopped our journey.
Example:
My boat = 0,0,0
Feel free to write about the intangible circumstances if need be.
Thanks, and travel well...
Bill

Re: Run Aground
You might try setting up a survey to capture this info.
And...some of us have run aground in all the above keel configurations, plus mono hulls and multihulls! 😆

Re: Run Aground
At least 2-dozen times. I do not really keep count.
Full keel, Fiberglass - no damage in sand and mud
Full keel, Steel - no damage in sand and mud
Catamaran, no keels - no damage in sand
Catamaran, ply keels - slight damage to fiberglass after hitting submerged rocks at 5 knots

Re: Run Aground
I've run aground in both sand and mud a lot - more times than I can remember. Nearly always trying to gunkhole somewhere, so max speed was about 1.5 knots and often less. Both in full keel and fin keel. Never worried about damage in either.
Hit a submerged log at about 5.5 knots with a fin keel. That I did worry about, but only enough to immediately inspect the hull and keel bolts from the inside of the boat - wasn't worried enough to have an unscheduled haul out to inspect (especially because she was coming out for the winter in a couple weeks anyway). Checked everything closely when she was hauled, and no evident damage.
If I had to guess numbers, it'd be
15,3,0
10,2,0-1 <-- the last number is 1, one time and the rest 0.

Re: Run Aground
1- loads (does tilting a bit to one side anchored & bumping up a river count?)
2- Steel long keel.
3- Really isn't a big deal

Re: Run Aground
What definition of run aground are we using. The hit bottom but got off, bottomed and waited for tide to get off, called the tow to get off?

Re: Run Aground
if ye aint been aground ye aint been around.
yup truly many times cannot count. all
\full keeled cruising mono, fin keeled mono, fullkeeled raceabout
first time aged 8 yrs. we learned marking twain at that time and we learned to read knots. learned a lead line can take samples of bottom. 1956.
didnot bounce off any rocks, only soft groundings and got off the shoals sola. 1956 we learned to unground a sloop with 6 ft full keel.

Re: Run Aground
In my boats, have run around in mud and sand more times than I can count, at all different speeds. In the Valiant I have always gotten off under my own power (knock on wood), not sure why. She's good at just muscling her way out.
Have only hit one solid underground object, was going a full 5-6 knots. Boat stopped almost dead while pitching forward and then up and over whatever it was, which was right in the middle of a marked channel at low water. Damage was just a quarter-sized sized dent in the lead and chipped fairing
Valiant, fin keel, skeg hung rudder.
Have run around on other people's boats more time than I can't count. Don't recall any significant damage (anything other than dents and chipped fairing/paint), even in race boats.

Re: Run Aground
Loads of times, my favorite was one of our first and scariest. We were inshore too close on a shallow submerged reef that went out a way. Dipped down as a big swell passed and bottomed out going about 6knt thought the engine blew except for the heave of the impact. Looked good under the boards, dockside dive showed a scrape in the encapsulated keel. A discovery 32 fin keel solid but thin fiberglass, but thick enough.

Re: Run Aground
Sail a centerboarder, a Presto 36, equipped with a lead grounding shoe, designed by Ralph Middleton Munroe in 1884 to be deliberately run aground, which I do with some regular frequency, for recreation(get to the beach), maintenance(the usual stuff), wait out bad weather or send the night near busy channels on a handy sandbar free from worry of being run down by larger vessels. Feel sorry for the rest of you guys, sand is my friend.

Re: Run Aground
1 - More times than I can count in the past 50 years. Able to get off myself in 5 minutes or less in all but four times. Those were mostly soft grounding.
2 - Mix keel types, full, skeg, fin, blub. No wings.
3 - Only damage. Once hit the unmarked sunken barge filled with big boulders, near Ft Wool, entering Hampton Roads Va. Wave picked up the boat and dropped it on the rocks. My heart went into my throat. Damaged the hollow skeg in front of the rudder. Nothing bad a little sandpaper and glass.

Re: Run Aground
Twice I've run aground where at the next regular scheduled haul out repaired the damaged glass on the encapsulated keel.
Every winter the locks/dam lowers the lake level. To get to my dock, I back up until I stop run aground in the ooze then I can turn, go forward and get in. Haven't counted how many times I've done that.
Can't give you the second number. You don't have a category for a standard commonly found fin keel spade rudder boat.
