Recommended software   There are several cad programmes available on the market developed especially for the purpose of yacht design. Most of them are priced to high to be worth considering for an amateur but there are a couple of free software solutions available that does the job with enough accuracy to be useful. After fiddling around with a number of them I have found that Delftship is worth recommending so we will use that for sharing design files.   Delftship files Download Piece of clay  Links Naval-Architecture.co.uk
