Unknown fitting on mast top of Swan 48

 

Hello friends,

does anybody know what the mount on the picture is for?

A rigger meant that the halyard of the genua has to get through with some role to make an angle with the forestay.

I am not sure if that is correct or nescessary.

Yours Matthias from Montana, Swan 48

Dear Matthias,

here you are, it is (I think) a Harken fitting to lower the genoa halyard.

Fair winds!

Thank you Matteo,

that is it.

But nevertheless I think we do not need it.

Actually, there is no interference between the halyard and the stay.

If I make some error in reasoning, please let me know.

Ciao Matthias

Dear Matthias,

you are correct, no interference on Montana's halyard , which is good news, so you can get rid of it!

I am very sorry to contradict you but interference is not the real issue.  The top mechanism of most furling systems needs that the halyard arrives at it with a precise angle which is achieved with that small pulley like in the second picture.  The angle is needed to avoid the halyard to wrap around the forestay during furling/unfurling (an extremely unpleasant effect, often seen).

The manufacturers of the furling systems usually specify the optimal angle for their products.
