Hi All
I am looking at replacing my SO 32 with a 379 shoal keel
I notice that the keel is only 30cm deeper than the lift keel version which will take the ground between tides
I wonder if anyone knows if this is also possible with the Shoal Keel version ?

Hi Dave
Guess it depends in what conditions you would think about drying out in and if you are planning to dry against a wall or posts? We previously had both a shoal draft SO34.2 and a First 305 that we both fitted with beaching legs and they worked really well for us.
The lift keel versions are clearly fully designed for beaching so will have a larger area for the keel to rest on, but I think with care you should be able to use legs or to dry against a wall.
Interesting I was told that the new SO349 shoal draft will have beaching legs as a factory option - which is something that has not been offered on Jeanneaus for a long while

Thanks Malcolm
I will be beaching on sand on the few occasions I actually do so
The idea of factory supplied legs is really interesting
Thanks for your reply
Dave

Hi Dave
To date we have never dried out with our SO379 shoal keel.... as Malcolm stated the you have more keel mount area taking the loads on the lift keel version... also you have re enforced end caps on both rudders, made for grounding.
Yes you have a large area on the wing keel shoal draft, but I would be more concerned about the rudders plus settled angles. Personally would not want to risk doing this by choice... but under certain situations and given the right ground conditions I bet you could sit her down without that much damage.
In answer to you question... As in standard spec I would say NO a shoal wing keel will is not made to take the ground in my mind much to big a risk. But would be very interested to find out any information on brave 379 owners who have?
Jim

 Everything is possible ;-) remember this photo of a SO40 on the Hamble spit in 2012 - deep keel and the crew stayed aboard the whole time.. |

Oh, man , that is really asking for serious troubles no ?
Was this done on purpose or what ?
What happens to the mast ( or the hull) when the boat would fall on its side due to a gust of wind ?
regards

I think the crew stayed in the cabin, I guess praying, The boat didn't shift at all, and all was well... |

That must of been a 6 hour nightmare while being awake.
I think I would make sure to put the boat on a side before alowing it to come dry completely.
Maybe wrap a few fenders around hoping they could protect the hull , if not deal with the hull damage afterwards.
That would be my choice instead of parading like a tightrope walker
All theories of course , better not get in a situation like this.
Regards

According to YM they grounded after loosing steering and managed to repair the problem before the boat re-floated. I've dried both my previous fin keelers ( Benny 305 and Sigma 33) against walls without issue. I can't see hull strength being a problem - is it any different to putting the boat on a cradle where the keel should bear all the weight? |

I can't see hull strength being a problem - is it any different to putting the boat on a cradle where the keel should bear all the weight? The problem is not the weight on the keel , it's like you say , same procedure as in a boatchair or cradle. But in a chair the sides are supported , in this case they are not. I'm pretty much convinced if the boat would suddenly go its side , the outside rigging would break off with all mast-issues as a consequence. And if a bolder/rock would be in the wrong spot , it could very well end up in the galley. Leaving a huge hole to be filled when the tide comes rushing in. Regards |

Re-reading the OP it seems that the intention is to keep the boat on a drying mooring, and I agree, any sort of fin is a bad idea for this. For occasional, attended, drying out against a support, though, there should be no problem.

I think this question should really go to Jeanneau, as they will know the design loads that they have engineered the shoal draft keel and rudders for. As others have pointed out, the lift keel version has protectors on the base of the rudders, and may have stronger floors to take the loads from the keel as the boat grounds. Please let the forum know what the answer is, as I'm sure there will be others who have the same question of the shoal draft boat.
