I have made the drawings public and can be downloaded by clicking on this link:
The file contains multiple drawings for bulkheads, interior and deck layout and DWG and PDF format. They, of course, match my project, but can be used as a base for anyone else with a Westsail 42 wanting to design modifications. Feel free to post any questions or comments. And, if anyone is interested in the VisualCADD native file format I can add them as well.
Note, that I have spent hours and hours on these drawings, transferring them from scans of the original line drawings. If you download these and find them useful, please consider making a donation to the build by clicking the PayPal Donate button below. Thanks!
