Steamhead on S. 47

Dear Lars,

while re-decking 47/069 Vanessa I took the opportunity to dismantle even the steamhead, would you suggest any specific reinforcement on this very sensible fitting?

Thanks so much in advance!

Dear Matteo

Two comments
- The headstay lug plate looks thin, if thinner than the gap in the toggle lower end, the recommendation is to increase the lug thickness to the maximum that fits.
- There is an extension piece at the headstay lower end for raising the furler drum. Should be checked that there is proper toggling action at its lower end. If you could send a close-up photo of this extension I can comment.
 
It is assumed you have removed the second forestay.
Kind regards
Lars

Dear Lars,

I thnink the welded spot is the weak one, I have been suggested to weld a 4 mm. thick plate on the outside side. What do you think?

Thanks in advance!

Dear Matteo

The corner shown by the arrow is a highly stressed area.
It is suggested an additional small triangular plate - say 20 mm edges -  is welded in there between the lower edge of the deck edge plate, and the stemhead plate outer edge, with a nice radius on the aft edge. Thickness as deck edge plate. 
Both sides!
Kind regards
Lars

Hello Matteo

It could be oif some help to have a close look at what I did with the steamhead of my beloved Farouche: reinforcement under the deck- prolounged front part on the bow and reconfiguration of the surface on deck with a larger area. 

Please see pics.

Hi Matteo,

Having removed the stemhead fitting on Sarabande, I took the opportunity to add another roller on the port side. This was in part to allow me to fit a sprit, but also to take heavy mooring lines which were too big for the cleats, and to save the hassle of removing the anchor. Since then, I have switched from CQR anchor to Rocna, which does occasionally "jump out" if raised too quickly, and I now wonder if further modifications are necessary to the fitting. I dont expect any of the above is of interest to you because they are not authentic etc, but sometimes sharing practical exoperience can be helpful.

Tidy bit of reinforcement Phillipe!

Very best

Rob

Dear Philippe and Rob,

thanks a lot! Actually under the deck I found the very same strenghtening (done by the previous owner).

I am very happy with the Ultra anchor, which fits on the original roller as it had been built accordingly, so, no need to modify it (and as Rob suggets, I don't like sprits).

Fair winds!
