I know because it took me, an experienced CAD user, nearly 3 weeks to create full sized templates for my Navigator build.
It's a task that every builder has to wrestle with.
Working with John Welsford, I have been developing a set of Full Size Template Kits for some of his designs.
These printable template kits are available in Letter (8.5"x11"), Tabloid (11"x17"), and E (36" x 48") and in metric paper sizes A0, A3 and A4. They are also available in roll-form (36" wide x 8-feet long). You print the templates on an ordinary home laser or inkjet printer, assemble the pages and cut them out to create the templates. Then simply trace the templates onto your plywood to get the full sized shapes.
These are great for anyone just starting their build. They're a big time saver and are accurate.
Want a closer look? You can download some free demo copies so you can see exactly how they work and "try before you buy" them. Each kit includes detailed instructions on how to use them. Although some pages have been omitted from these demo copies, you will still be able to see what is included in the full versions by looking at the table of contents and the page arrangement diagrams. You will be able to print a template, assemble it, test it, and see how it all works, all for free.
Template kits are available for Navigator, Pathfinder, Sei, Tender Behind, Pilgrim, Longsteps and Walkabout.
The template kits are now available for purchase as an instant digital download from Duckworks. Or can have Duckworks print and mail the roll-form sheets to you. Here is the link:
