SELF-TACKING SYSTEMS
Antal has two solutions for self-tacking using track and
travelers of the new 4RACE system.
The first solution (Dwg. 1) needs
a footblock for the sheet on one side of the track; the sheet, from this footblock,
goes to the cockpit. In this case the track will be curved only in the horizontal
plane.
In the second solution (Dwg. 2 and 3) the sheet climbs up the
mast then down and to the cockpit as a halyard. In this case the track will
be curved vertically and trimmed forward.
Travelers with one or two sheet
blocks will be used.
Double cars are often considered because a shorter
car accepts a tighter radius.
To control the traveler moving it will
be useful to consider also two side stop-pins (mod. 4290) and consequently the
track for stop pin (mod. 4520).
Systems of drawings 1 and 2 are obtained
with 2 x 110 mm travelers and 2 x 65 mm blocks (for boats up to 50 ft), or 2
x 150 mm travelers and 2 x 75 mm blocks (for boats over 50 ft).

There are 4/5 different positions
for the sheet block that will be simply fixed with an HR shackle.
