I received our C&C 43-1 digital drawings this week and had a chance to give them a good look over. We purchase a little over 20 drawings, both the digital and printed copies. The printed full size copies are should be delivered in a week or so.
The purchase was worth every penny. On the keel drawings are hand written notes listing the actual weights of the first 3 castings of both the iron and lead parts. Also, the keel drawing shows all the bolt locations including some between the lead and iron parts that I had not found (they are buried inside the keel assembly). Calypso's mast and fittings are all custom (the fittings are overbuilt, fabricated SS). The drawing package included dimensioned drawings for most of the fittings and the spreaders. If the mast ever get damaged we now have an excellent starting point for the repair. We also got the original chain plate drawings. I found some additional drawing numbers relating to the spars and have requested them from the museum. As Calypso is hull #1 of the custom 43 series many of the hull build drawings have additional notes regarding fiberglass lay-up details that I was not aware of including extra lay-up in high stress areas and where the balsa starts and ends. Along with the "as built" type drawings are the early 1970 conceptual deck and interior drawings used to sell the project to the first buyer. It is interesting to see how the design changed from the early marketing to actual build. The rudder drawings include the first rudder and rudder bearing assemblies which show the rudder's stock details and the massive bronze casting that makes up the lower rudder bearing assembly. I also have the drawing of Calypso's 2nd rudder which is deeper with additional inner SS structure. The icing on the cake for me is the drawings that show the transom modifications performed in late 1973. It is a relief to know that the original C&C design team engineered the change including how much additional lay-up was needed to maintain structural integrity. This drawing will be very useful if we decide to restore the original transom shape. Martin DeYoung Calypso 1971 C&C 43 Seattle [Description: Description: cid:D1BF9853-22F7-47FB-86F2-4115CE0BAF2F]
