1979 Swan 57 rudder

Hello 

I am in the middle of a refit on my Swan 57 and wish to drop the rudder. I understand that the shoe is attached to the heel of the skeg with a steel plate, which I would need to remove. Where I am concerned or unsure is does the whole heel of the skeg drop and stay with the rudder or do I just strip all the glass below the shoe and slide it off with the dropping of the rudder?

I can see evidence of previous repair work, but am trying to not create more destruction than needed. 

A few photos below of where I am at

Thanks for any help in advance

Dear Swanning Around
Originally there was a removable fairing piece at the bottom end of the skeg below the steel fitting, removal of this piece enabled the fitting to slide down together with the rudder.
If you want to remove the bottom bearing from the rudder stock there are two alternatives
- either remove the blade from the stock
- or make a cut-out in the blade below the bearing.
Pls note that there are removable fairing pieces along the trailing edge of the skeg, and along the leading edge of the rudder.
Kind regards
Lars

Thanks Lars

All was a success. Safetly managed to drop the rudder by sliding the stock and blade down the core of the skeg.

The design on the 57 seems to be different (and weaker) compared to earlier Swans. The picture below is from Swan 44.

 

 

That design and size seems much stronger.

Anyone have comments on this?

 

Best regards,

Dear Bjorn

The Swan 44 bronze shoe is rather strong, but the section of interest is at the upper edge of the shoe, where the GRP is stepped all around to a smaller section in order to fit within the shoe. The bearing is located some distance down from the upper edge, creating an additional bending moment in the GRP section.
 
The Swan 57 GRP skeg is only partly stepped, and the bearing is right at the upper edge, this results in a stronger GRP section seeing smaller loads.
 
Kind regards
Lars
