The contract that you have gives the moulded dimensions at each end of the floors and most of the futtocks so you can see the amount of narrowing each frame does in the in and out direction, It is gradual unlike the stepped reduction in the sided direction. The sills will be the same dimension as the in and out/'moulded dimension of the frame at the point where the sills are set in place. I hope this makes some sense, because as I read it back, I am not so sure.OK Allan I will try it on a test piece. I need more guidance though. I imagine the correct size would result in an attractive 'slender' appearance, but I'm not clear about the rate of taper e.g. If I do so, how 'thick' should the upper and lower sills be for the gunports? Upper sills around midship might be very thin.
