Bottlescrews

We have adjusted Blue's mast rake, bringing it forward to try to reduce the weather helm.

The aft lower, port shroud bottlescrew now has about 3/4" - thats 0.75", not 3 or 4 - of screw in the bottle, so to speak.

Is that enough?

If its a good snug thread, not a worn wobbly one,
Put a toggle thingy on.

Andrew, I'll post a photo after the weekend, but a toggle thingy looks ideal.

I love all this tech speak.

I read somewhere that its only the top few threads that take all the load?

Technically the load on the threads decreases exponentially as you go down the thread away from the top. however if the load is such that plastic deformation takes place (put too much load on) rather than elastic deformation then the top threads will deform and spread the load further down the thread. In other words, whilst the top threads take the strain, if put to work they then pass the load on to their buddies further up. Team work.

So more thread is best when you may really need it. A toggle thingy would get my vote.
