The Eider is a simple plywood duck punt suitable for river and canal rowing and some quiet fishing. We have given her a small transom stern to allow more stowage space and so that she could take a small petrol or electric outboard if required. She is 11'6" long and the plans give the panel shapes for two versions, one with a beam of 3'11" and the other with a beam of 3'4". The larger beam version is ideal for fishing and for taking passengers, whilst the narrower beam version can be used for serious single rowing. 4 sheets of 6mm ply are used and the construction method is simple stitch and tape keeping weight to a minimum. She could be used with a simple sail and leeboard.
