This is a scan from the 2010 Comp Jet Rulebook. Unfortunately the rules on the APBA website have not been updated yet to reflect the rule changes.
One of the major rule changes for the 2010 season is #1 which is requiring boats to have full stringers through to the bulkhead forward of the driver and the seat/seat frame must be through bolted to the stringer, not the sub floor.
If you are a member, you should have or will be getting your 2010 rulebook in the mail. These are being posted here for Public Notice. These rules will be updated shortly on CompJetRacing.com as well.
