As noted in our Tow Boat Committee report to the BOD, the Tow Boat
Committee has approved Zero Off Speed Control for use in AWSA
sanctioned tournaments. The Rules and Technical Committees have requested that
we verify the “virtual times” recorded by Zero Off with back up timing recorded
from an independent magnetic timing system (i.e. Lockett, BTS or other
available systems). In actual AWSA sanctioned tournaments the data from these
tournaments is to be forwarded to Will Bush, Tom Danford, Gene Davis & Tom Dusin for analysis. When the Rules Committee meets in
November 2007 it will have the data generated from tournaments using Zero Off
and will decide whether continued use of back up timing will be required for
Zero Off or if independent GPS based
“virtual timing” is acceptable.
Dave Doige representing Correct Craft voiced
his concern regarding the length of time required for verifying Zero Off
virtual times with a back up timing device. Correct Craft is ready to ship 2008
model year promotional boats with Zero Off but does not want to incur the
additional expense of
equipping their boats with
an additional back up timing system. The Tow Boat Committee will contact the
Rules and Technical Committees to further discuss these issues and will keep
all tow boat manufactures informed.
The power and acceleration standards for AWSA Approved Tow Boats were
discussed. Due to EPA requirement that
tow boat engines be equipped with catalytic converters (and their negative
effect on engine performance), greater wetted surface on the larger boats
manufacturers are providing, and the control advantages of drive by wire mated
speed control, we agree that the existing standards for power and acceleration
may no longer be appropriate. I spoke with Will Bush on Saturday, August 19th
and we agreed to review the existing standards, evaluate radar traces from the
2007 model year tow boat tests and recommend for discussion to the Tow Boat
Committee revised power and acceleration guidelines. We will have updated power
and acceleration guidelines-to be agreed upon by the AWSA Towboat Committee-
for our next AWSA Tow Boat Test. Aarne Clow recommended that we try to gather more skier input
regarding the “skiability” of tow boats at our tow
boat test. He recommended having a greater number of skiers participate, or
possibly as part of the test, sanction a tournament where information would be
gathered under actual tournament conditions.
2008 model year tow boat tests were tentatively scheduled for October
6-9, 2007. It was noted that
I will keep manufacturers and test team members appraised
regarding all of our discussion items.
