FIRST: I have plans for a "WARATAH TWIN BILGE KEEL MASTHEAD SLOOP"-21ft long. I have these plans 'cause my grandfather purchased them in about 1971 and built his own version. It was designed by DENNIS KNIGHT of Gosford in the late 60's. Unfortunately I placed these plans under my bed when I was a teen and my then dog chewed up 3 of the 7 sheets (beyond repair= confetti)-(Hello animal shelter!). Fortunately I still have the spec's sheet. SECOND: I have 3/3 sheets being blueprints (included is the spec's sheet) for a "CLIONE" 37ft 7 inch DOUBLE ENDED KETCH". Build no: 430. December 1938. Designed by William Atkin & sons, naval architects & engineers, in Darien conn' (not sure where this is?). THIRD: RESTRICTED RAINBOW CLASS YACHT/ AUSTRALIAN RAINBOW COUNCIL. (small 1 to 2 person open cockpit yacht-12ft) Designed by RJ HILL, plans drawn by JR GLUSKIE, may 1957. Plans issued by Jock Campbell feb 17/1962 in Hobart, Tasmania. ALL plans were passed to me from my now deceased grandfather. Can someone give me info' on copyright laws or what restrictions apply to producing copies of the 3 designs in order to sell said copies. Now I know these threads can run wild with thoughts and "maybe's" but I would like firm and specific info' please.
