A nimble double kayak. The Eider is designed to be a family day boat.
As an open cockpit boat it will be very flexible in its use, being able to carry a single paddler sitting in the middle, two sitting near the ends or combinations of adults, kids and dogs. The open version is designed to be used in calm, protected waters such as lakes, rivers and ocean coves.
The double cockpit Eider is intended for day trips and overnight camping trips. She will have comfortable and fairly roomy cockpits which are far enough apart to avoid banging paddles.
I have an Eider Double here at the house for you try or purchase
Eider plans include full size templates (tape the sheets together and mark your plywood by punching through the paper) and detailed easy to follow instructions. This boat uses stitch and glue construction and can be assembled in about 110 hour of work.
