Daniel, I agree with the assumption that we have no problems with the attachment of our keels.

Lars, very interesting and many thanks. I am away in Africa for some time so cannot assist with measurement. Hopefully others can so you can conclude this very interesting topic. |

Lars I am now back and Avista still out of the water. Can you just confirm in not too technical language what further measurements you require. Some time back when re-working my mast step I took these photos. The lifting plate further aft which was a huge steel triangle I have removed as it was always very rusty. I replaced these with 3 very large S/S washers as you see in the photo.

We have been working on the details off line and I think we can confirm that certainly the 411 would NOT meet todays standard of attaching keel to hull. This is mainly due to the thickness and size of washers used on the bolts. They do however comply with Lloyds 1001A standards. As I know of no cases where S&S Swan keels fall off sailing and seemed to have survived many a crash I think we do not have to worry too much. It has been a very interesting topic with many more questions raised. Are the new standards higher or just different? Why did Swan attach a lead keel with stainless bolts to the hull as Bronze is recommended? |

Lars, given that a new Oyster 825 recently sank after losing its keel, I am quietly confident after 36 years afloat the chance of anything falling off my yacht are pretty remote.
