Here are the fins before painting

Fins installed on the boat

The fins are 1 1/4 " tall, 3/16" thick and 4' long. The are installed parallel to the skeg about 17" from it. The are tapered on both ends and pretty thin so don't have much drag and are short enough so they don't cause wave slap since they are never out of the water. The oyster beds are going to be a little tough on them but we'll see.
