This project can be found at:
This is a step-by-step documentation and explanation of the project found on that site. I've tried to simplify some of Hannu's steps for laymen like myself. You will need to refer to that page as you read this Instructable. I won't repeat Hannu's instructions step by step since this is really his design. I'll just explain how I did it, what problems I ran in to and how I got around them.
If the link to Hannu's website ever changes (I discovered that it had) please Google Hannu Vartiala and his new website should come up.
This project tool me about 3 days for the first boat and 2 days for the second.
I will also include tips for oar construction, which Hannu did not cover in his project.
Step 1: Cut the materials
With the first sheet of plywood you can cut out two side pieces and two transoms (the back end of the boat). Measure carefully and you'll be fine. Refer to Hannu's diagrams for dimensions. The first boat I made was the larger of the two.
I used a skill saw and sawhorses to cut the sides and transoms out of the wood.
Since I was already cutting, I used the last two pieces of plywood to cut the sides for the second, smaller boat sides. I kept the larger remains of both sheets of ply to cut the bottom of the boat from.
To save yourself some time in the long run, I suggest you order your oarlocks now. By the time they reach you the boat may be ready.
I found a decent deal at www.shipstore.com, specifically this item:
This turned out to be the only real hardware I couldn't make myself.
