The Areoscaph measures 25cm in length and 6cm at its widest point.From the top of the cokpit to the widest point on the underside it is 9cm deep.
I will measure the Martian floatship at the weekend.
I was a little disappointed with the size of the Areoscaph it looks more like it should be for 20mmor 15mm figures. The foalt ship is fine though and will house a number of figures on the deck.
