Drawing plans of Spinnaker

Having only been given the above elavations for the tower i was left with the problem of drawing the side elavations, rear elavation, front elavation.. This was a big challenge as i spent a lot of time trawling the internet for any information about heights of the tower. One of the hardest things to work out was the size and shape of the bows as the only information i had was from above. All of the pictures shown from the side didn't give a very accurate view of what size it was as it varied from the middle, top and the bottom.
