I had the misfortune of running aground this summer on my 370e. While I was only motoring at about 3 kts. it was a rock and I suffered some damage to my keel.
 
Does anyone know the keel construction  of the 370e. Is it all lead or glass and lead etc?
 
Also has anyone made any keel repairs? Any advice would be great!

If you have the 370 # 3 it must be a kompositkeel, it is shaped like an L. The top is made out of cast iron and the lower part ist made out of lead.

Only the boats with production number over 500 (Do not know the exact number, but may be mine was one of the first (#522) with an T-keel) may have a complete cast iron keel. That is the T-Keel.
 
T-Keel = cast iron
L-Keel = compositkeel with cast iron and lead
 
I hope the damage is not severe. Do you have fotos?

I know there is a topic or post that has been set on this forum in the past from I think a 411 who had to remove the keel.
Problem is I can't find it....
But the bulb from lead was bolted on the finn and the finn is bolted to the hull , that is wath was visible on the pictures then.
Succes

As PB said above, it will be cast iron top with a lead lower portion. When the keel is removed from the boat, the bottom of the boat is flat - in other words, there is no fiberglass "skeg".  I've seen a bent 400 keep, it bent at the join between the iron and the lead. The bolts that join the two portions are embedded making it difficult to fix.

I am wondering, that you hit the rock with "only 3 knts"
If you have the lead keel, it may be that your lead part is deformed a little bit. This part of the keel should be easy to repair. with 3 knts, i think not more should happen with an L-Keel made out of lead.
This will end very diffrent if you hit the rock with a cast iron part or if you have a cast iron keel. Steel is not that "soft" as lead may be.So it would be interesting to see some fotos

Thanks for the info. I will shoot some pictures today. It is an L shaped keel. It does look like lead and it was really more of a glancing blow vs a true hit. Fortunaley it did not do any hull damage.
 
Thanks,

Jeff

I was on a 34ft boat earlier this year that did the same, we hit a rock on the bottom 300mm of the keel (lead) there did not apear to be to much damage we were traveling at about 4kn. after the boat was lifted it turned out that a keel bolt had broken, the grp stringers in the hull had stress cracks and the nav station and galley had moved 100mm up the bulk head and then dropped back down as the hull flexed. All the holding tank fixings still need to be checked (fuel and water) as you can imagin the impact of 200lts of fluid suddenly stopping and sloshing back and too in the tanks.

I would recommend a full survey to ensure that there is no hidden damage. better to find it now than in an F8 at sea.

Here is a link to the topic Marcel mentioned yesterday, I suppose:

 http://www.myhanse.com/forum_posts.asp?TID=1759&KW=keel

 
If the link doesn’t work, the topic is “Keel bolts loose” under “Chit Chat”, and the date is 8th of January 2008. The boat is Hanse 401. The pictures are interesting, indeed.
