I decided to use white ash because it's easy to bend without having to steam it. White Ash is a relatively light hardwood and also highly impact resistant while being able to hold a screw and other hardware firmly. I purchased the raw wood from Noah's Boat Building supplies online. It took two 1x6's (Actual dimensions) that were approx. 8'-6" long to have enough for my 14 footer. I believe it cost me 85 bucks including shipping for the wood and I had it within 1 week. Luckily I have a buddy that has access to a high school wood shop and a table saw. I had to rip ea. board in half to get them down to 7/16" thick (1/8" saw kerf)... in the end you have eight 7/16" x 2" x 8'-6" gunnel boards after alot of ripping of the boards. I then sandwiched the upper edge (1 inch) of aluminum between the two boards. Using a bunch of clamps, set your boards in place and drill and screw. Every other bolt goes through the aluminum and the wood while the rest of the bolts go through just wood (see photos). The real key to being able to sandwich your boards together tightly is to cut a saw kerf in the lower half of one of the halves so that you allow for the thickness of the aluminum. I made this "groove" 1 in. tall along the lower half of the gunnels. This groove makes it easier to set your boards in place along the top edge of the aluminum too just prior to clamping. This is hard to describe, so if I'm confusing you let me know and I will try harder and take better photos. Since UPS can only ship 9 foot long boxes, I had to splice two peices together to get the full length I needed and just hid the splice behind a set of oarlocks (see photos). I also worried about this step of the restoration more than anything else, so I hope this helps others. When I was searching the internet for others with a similar boat, I couldn't find anyone!
