Inner Gunwales
6 pieces 2.4m 16mm x 35mm Clear timber for gunwales. Spruce or a light hardwood like mahogany makes for nice light gunwales which are easy to form to shape.

Outer Gunwales
2 pieces 2.40m 20mm x 25mm. Hardwood like mahogany wears better than the softwoods.

Framing
1 piece 16mm x150mm x 2.40m approx for both transoms

Daggerboard Case Side members
2 pieces 27mm x50mm x 400mm

Mast step
1 piece 100mm x 60mm x 180mm

Glue
Approximately three litres marine epoxy glue for laminating parts and coating hull

Hardware
#8 x 3/4" screws. Normal steel since they will all be removed after gluing. The glued joint is stronger than the screws, so why carry around the extra weight.

What will they cost?

The following prices are taken from the internet (search for "marine + plywood") and appear to be average current ex-warehouse retail prices (US$) from major suppliers:

1	Sheet 1220 x 2500mm 12mm plywood	$85
1	Sheet 1220 x 2500mm 6mm plywood	$50
1	Sheet 1220 x 1250mm 12mm plywood	$45
1	Sheet 1220 x 1250mm 3mm plywood	$20
	Timber for gunwales etc.	$50
3	Litres Epoxy	$80
	Fittings*	$170
	TOTAL ?	?$500

Not bad when you think that the lowest priced GRP Optimist hull will cost at least twice this!

* 3 buoyancy bags, mast-step, rudder fittings, padded toestraps, fixing plates. Some of these may be available from local chandlers. If not, maybe your nearest GRP builder can help or try Optiparts in Holland who claim to be the "world's largest supplier of accessories for the Optimist dinghy".
