1 Rig for racing 1
1.1. Hull, rudder and centreboard
1.1.1 Hull
• smooth with no major imperfections
• clean fiberglass with fiberglass cleaner
• fill imperfections with epoxy and micro-balloons
• final sanding with 600 paper
• put extra effort into the first and last three feet of the hull
1.1.2. Rudder
• front edge must be vertical when in sailing position;
• sides of the blade to be smooth and flat;
• leading edge to be rounded into a parabolic shape;
• shape leading edge to razor sharp for 1 inch above & below water line;
• trailing edge to be tapered to a “V” shape 2 ;
• the back of the “V” is to be cut off flat about 0,3 cm (1/8 ") wide;
• tapering of rudder (chamfer) is not be more than 5,1 cm (2 ") in from the edge (max.
permitted by Class Rules);
• rudder fittings must be strong and well fastened;
• through-bolt fittings wherever possible.
1.1.3. Tiller
• Must be close fit into rudder stock: no “play” - if necessary, put tape around the wood so
that it just fits.
• rudder tie-down to be heavy, double shock cord 3
• need a tiller extension with good grip (tape every 15 cm) – try “golfball” technology: a golf
ball fastened to the end of the tiller extension makes it easy to steer when hiked.
1.1.4. Centreboard
• sides of the blade to be smooth and flat
• leading edge to be rounded into a parabolic shape up to 6,4 cm (2.5") in from the edge (max.
allowed by Class Rules)
• trailing edge to be tapered to a “V” shape up to 6,4 cm (2.5") in from aft edge (see also note
on trailing edge or rudder) the back of the "V" is to be cut off flat about 0,3 cm (1/8 ") wide
• when the CB is fully down, the leading edge must be raked slightly back so as to make an
angle of no more than 83º (Class Rules) when fully down
• the CB must extend down from the keel no more than 100,6 cm (3’ 3 5/8”) (Class Rules)
1 Check class rules for detailed specifications and limits.
2 Al Schönborn’s note: This is a good wood to make the wood core. In sanding the glass or epoxy
covering, I try to give this edge an air foil shape, too. See also trailing edge of centreboard.
3 Al Schönborn’s note: I like to use mostly 4-mil pre-stretch rope with a 6” loop of ¼” shock cord
just before the end that goes around the hook under the tiller. I use a bowline to tie another 6”
piece of 4-mil rope onto that loop. I then use that little piece of rope to drag the shock cord
over the tiller hook. This holds the rudder down very well!)
