Manfred,
Thanks for your input. We look forward to working with your group. As you
can see from the responses on the list, getting help with the process is
never a problem.
It is always good to see builders trying different ways to rig the Swift.
One thing that should be pointed out is that the two masts that have likely
seen the most use (002 and 013) have the spreaders built and attached as the
rigging manual shows (and as Manfred suggests). Neither of these masts have
had any spreader or other failures. This direct bonding method is clearly
lighter, however, you can not remove the spreaders for shipping (the
downside).
If you should break a spreader, it will take a bit longer to replace than the
collar system as well, however, it can be done overnight at a regatta as
long as you carry a couple of extra spreaders with you. Built properly, there
is little likelihood of breaking one except possibly in a crash with another
boat (sparing). Weight aloft is a big deal! Spreader rake (sweep) and
length is another significant issue. We have learned that longer and less
sweep
is clearly a mistake, however, we have not really tested the other end of the
spectrum. If I were a lightweight (stop laughing), I would be inclined to
try 8 inches of sweep and perhaps a bit shorter. This is only a theory--but
one that I'd try!
On a different subject: after several sessions with / against Ron Watt, we
have concluded that releasing the leech and luff lines completely on the Banks
kites as they age solves all of the light and moderate air speed and tight
reaching problems. I should have known this from my 49er experience but it
somehow slipped my mind until recently. I was in the beginning stages of
working with Dale at Banks on a redesign of the kite but now believe that it
is a
waste of time. Believe me when I say that releasing these lines will improve
your downwind boat speed more than anything else you are likely to do.
Best regards,
Bram
