Optimist One Design racing foils from Optiparts are built according to the new class rules. Class rules have standardised Optimist centreboard and rudder: size, shape, epoxy, foam and fiberglass.
Both Optimist rudder and centreboard are made to the maximum allowed thickness to create a foil as stiff as possible under the given rules. The One Design Optimist centreboards are fitted with nicely finished teak wood battens.
