Okay, here is what I've put together in the back yard, bear in mind I am a complete beginner and don't know most of the terminology.
Not sure how correctly it is set up, please offer advice where corrections are required.
Measurements for Christina are as below, I haven't got rudder/tiller system mounted so as to keep it off the ground and not have any weight on them. As Mav says there isn't any tiller extension, but I will probably make one to suit.
Mast = 6100mm
Forestays = 4475mm (overall wire length)
Backstays = 4350mm (overall wire length)
Lanyard wire = 540
