I decided to start by finding a good set of kayak plans and modifying them. After looking around for a few days, I came to a conclusion.  I had 2 options: 1) buy plans from someone and build a copy of a boat that 1,000 people already have, or 2) design my own unique boat.  I choose the latter.

I designed my boat using Ross Leidy's Kayak Foundry software.  I owe the success of this boat to Ross.  He graciously answered more than a few emails throughout my build and shared many useful tips.  THANKS, ROSS!!!

With Kayak Foundry, I designed my boat and printed all of the forms I needed to build a full size skeleton.

With the printed Kayak Foundry forms in hand, I pasted them to a sheet of 3/4" MDF with a can of spray glue.  In hind sight, using contact cement and a rolling pin to flatten them out would have been a better idea.  They kept working loose when I cut them out with a jigsaw and through the build.

After I cut out the forms, I used a laser level and the center line, which gets printed on the forms (Kayak Foundry is AWESOME!), as a guide to draw a squared box the size of two 2x4's. I then proceeded to cut the holes with my jigsaw.

The forms were then aligned via laser level, 12" on center, on a pair of 2x4's that were screwed together.  I wrapped each form with duct tape to prevent the ineveitible wood glue drips from causing the whole boat to stick to the forms.  This assembly is now ready for the next step - attaching the stem strip.

I should have taken more pictures of this step - and not with my cell phone.  Next time...
