Thank you the kind comments, I'm heading for that anniversary Nemo.
I have been working with the fiddly bits and mass production sections and am pleased to show all her lifeboats now on board.
I am concentrating on the Bow section at the moment as the railings are still on back order, so took a chance with the lifeboat assemblies.
As the weather has improved, I have taken her outside for her first float test in the pool. I am pleased to report there are 'No' water leaks into the hull. It was glassed on this precaution in readiness. She floats fine without the top section fitted but (same as the Titanic I built) when the upper works are fitted she rolls over as expected.
I fitted an assortment of heavy lead batteries to the hull to test for the 'tip over' factor and determined she will need ballast in the keel totalling over 15 pounds and fitted as low as possible. (phew). Failing a successful balancing act then I will go with Colin's suggestion (for my Titanic) of a removable drop keel, like a yacht.
Here are some pictures of the progress.
