It Works
Picked up the boat on the trailer Sunday night (Thanks Peter!).
Only needed to make a small adjustment on the rear cups. They are made from 240mm downpipe and needed some warming and bending over the BBQ to fit the hulls. Excellent idea, but if you use 300mm downpipe it has the same shape as the rear of the hull - just cut and use
There is so far only 1.5 coats of paint on it so it needs more, and the box and spare needs to go on. Then we are pretty much done for the moment.
I have already thought of a couple of refinements but they may have to wait for a bit. I am itching to play with the boat part of it all

I will post some pics of the boat sitting on it next weekend, and if anyone wants measurements I will do a drawing at some stage.
