Any reasonable cheap non-programmable scientific calculator will do. We recommend the Casio fx85, but there are lots of others. You don't need a specialist navigation calculator, such as the Jeppesen.
CRP-5, Douglas (square-shaped) protractor, and the Pooley ruler with a quarter-mill scale on one edge and a half-mill on the other.
You won't need a ruler that measures in inches or centimetres.
Dividers/compasses that don't have a screw mechanism to change the distance - Rotring are probably the best.
A propelling pencil with an HB lead of 0.5 mm diameter.
And either a chinagraph or a WATER-BASED felt-tip to mark up the wind face of your CRP-5. Staedler Lumocolors are a good make - but get the grey-barrelled ones - they are water-based and removable. The black-barrelled ones are spirit-based and permanent - you don't want one of them.
