Hello Captain Taff Sir, standing to attention my dear Sir, no pun intended?

I have some information in a book on the build of a Sirmar Hull.? I will email to you this evening, hopefully I will have put my hands on the book by then.
When you say 'stiffening around the upper deck' are you speaking about 'underneath and around the bridge wings?'? can you enlighten me on that please?
These are lovely models to sail in all weathers, the only drawback the actual weight of them, that is when they are balasted in the water.
Yes, I did have working stabilisers.? Yes.
It was a mechanical setup to operate the stabilisers, with mechanical linkages to a swinging pendulum in the middle of the boat.? ?
For the Leeds Castle, which also has operating stabilisers, I changed this to an electronic drive, sensing the movement of the pendulum.? This is far more reliable, than the old mechanical one.
Hope this is of some help, I will come back later with some information for you.? ?Carry on with your build, this model is a lovely model to build and could possibly be a re-build for myself, along with many others?

Aye
John e
