Halving the load on the rail, using a 2:1 lead to a magic box.
The 2:1 is still popular, though the magic boxes have been replaced
by 6:1 wire tackles, running in front of the diagonal bulkheads, on
many newer boats.
An Aussie boat with hydraulics on the shrouds. Very shortly after this,
the Aussie's went to the low tension rig! I believe none of them use
hydraulics now. This may still be an elegant solution for the high tension
rigs popular in North America and with some Europeans.
Shrouds go to cars on tracks. This setup was used by Benj (Steve Benjamin),
and several others. It makes adjusting shroud tension while racing
difficult, but provides an effect similar to changing spreader angle while
sailing. There were several 505s at the 1981 World Championship that
had spreader angle adjustable while sailing, though it took a heavier
spreader bracket and two more wires running inside the mast to do it.
An all wooden 505 - WOW! This boat was - I believe - cold molded. The B&W photo
does not do it justice; it was beautiful! This boat was German. At the time,
Galletti in Italy was building all wooden 505s. I do not know if this was
Another view of this incredible 505!
Waterat delivered an unrigged boat, 7349, to the Worlds. Check out
the shine on the oak veneer tanks! Unlike the all wooden boat, this 505
is a wood look boat. The hull is a honeycomb cored Hamlin, the
foredeck and seat tanks are foam or honeycomb cored epoxy kevlar, with
oak veneer on the tanks, and mahogany on the foredeck. The diagonal
bulkheads, centerboard trunk and thwarts are wood. This boat is still
one of the top 505s in California, fifteen years later.
