deviating forces inner stays to the hull

[hanskesteloo]

Hi
I own a JSO 29.2 and it seems that my deck is being deformed due to the forces on the inner stays. Inside the cabin you can see this, because the inner scale of the ceiling is parting near the bulkheads near the main windows and at the front bulkhead. (the inner scale is connected with kit or glue to the wooden bulkheads)

The attachment of the inner stays to the deck is of a very light construction and one wonders why the mast remains upright altogether
I would like to deviate the forces partly to the construction of the hull, ie attach a plate to the horizontal beam (rafter) located just under the bunks; connect this plate with a metal rod to the bolts of the stays. With a tensioner it is possible to "pull back " the inner scale to its original position.

Are there any owners with the same problems and is my idea indeed a solid solution?
Regards
Hans

The result?

I am suprised the inner stay is not already taken down to the keel/hull. The feature you are considering adding is present on all boats I have owned in the past and as you say I am suprised the mast stays up at all! This seems to me to be a failing in the build construction and I think you do need to carry out the modification. Have you queried your local dealer at all?

Hi,
I know a lot of boats do have this as a standard, normally to support the fitting where both the inner and the outer stays are attached to.
The Jeanneau SO 29.2 has separate fittings for the inner and outer stays.
It seems I am not the only one with this deformation; in a Dutch forum I have come across a similar case.
All in all the construction of the 29.2 is "light" .
In the mentioned forum however the "specialists" state that most forces are supported by the outer stays and that the inner stays are merely there to prevent the mast from bending.....
The Jeanneau dealer agreed with my idea to strengthen the construction. He advised me to add more "body" to the stringer where I want to lead the forces to.

Hi,
After a lot of "investigations" and hard labour I solved the problem. I strengthened the stringer with wood and laminated this to the hull and stringers. I attached a metal rod and spanner between the stringer and the stayattachement.
The deck is now back in its original position

Hans

very neat solution

No doubt will be really valuable to other SO29.2 owners
