Description
I was asked to design a handy little double ender for construction in welded aluminum and the Avocet was my answer - however, aluminium is not everyone's preferred building material and so I have redrawn/designed the Avocet for construction in plywood and called her the Wader.
All aspects of the Wader are the same as for the Avocet - so she is beamy, robust with enough space for a decent self draining cockpit, 2 berths a Porta Potti wc and sink and cooker.
The rig had to have as few strings as possible and be easy and quick to put up whilst the hull needed to have a shallow draft without a centreboard an be able to sit upright when she dried out.
The ballast keel box is a simple plywood box partly filled with lead shot or a combination of scrap steel and concrete.
Motor power comes from an outboard mounted on a beam across the quarter deck.
