Rowing the San Juan Islands in the Drake Rowboat
Sponsorship and Commission Opportunities
|The hull lines for the new KDI sketched out.|
|The Drake Raceboat has been modeled in the computer but that is it until sponsorship comes along.|

Hull Modeling in the flesh: part 1
CNC cutting parts for a quarter scale model
|The 3D computer model is sliced up into sections that become molds for defining the hull shape.|
|You can see the molds formed now, trimmed to the hull surface, and one more to go!|
|The hull is planked and ready to be broken up into the "flat" 2D geometry.|
|A neat screenshot that shows the 3D and 2D nature of the work: in the foreground is the 3D hull model. In the background is the geometry flattened onto the "construction plane".|
|This is the file with the 2D geometry as received by the CNC cutter, CNC Routing & Design in Camden, Maine. Tim will load the file into his Shopbot software, make toolpaths, and cut the parts.|
|The ShopBot machine cuts to my lines with a couple thousands of an inch accuracy. These are the planks of the boat, the bottom keel plank in the center and the sheer strake to the far right and left.|
|The molds of my quarter scale kit around which the planks will be wrapped and checked for fairness and for fit.|
to The Compass Project in Portland, Me is building a DSD with a group of kids and they are doing a great job.
The boat is built like dories have always been built, using the bottom to erect stem, frames, and transom, then turning over the boat upside down on a strongback. Everything is plumbed and braced then planking begins.
Here the garboard has been installed and the sheer clamp is being fit. This is the only departure from traditional dory construction, the incorporating of the clamp helps tie together the frames into plumb and lock in the ends of the boat. It is a bit of a 3D puzzle!
