2019 THAI AIRWAYS WORLD CHAMPIONSHIP CLASSES AND GUIDE:
IJSBA has released a final finalized class list for the 2019 Thai Airways World Finals. We appreciate those of you who provided insight and comments the last few days (though we wish you would have sooner) and the World Finals intends to reflect a series of core classes as well as elective classes which the community believes are important to offer to reflect the sport.
Competitors are advised to closely read this guide as it reflects some changes in class definitions as well as some direction changes that are being made to consolidate a single premiere Ski Class and a single premiere Runabout Class. The consolidations are made pursuant to be in harmony with the World Series system that has debuted for 2020. Competitors should note that there were some language translation issues at the beginning of the World Series that caused a mismatch between the class names and rules associated with the class names. This guide includes the classes that will be run at World Finals and then a chart to where these classes match up to the 2019 IJSBA World Series.
Note: World Series Pro Ski Grand Prix class used a consolidated rule set to merge Ski GP and Ski Modified, IJSBA will run this identical class at the 2019 World Finals as Pro Ski Grand Prix allowing aftermarket hulls, up to 97 inches (plus allowances for extended ride plates and nozzle length) with 1500cc Naturally Aspirated Displacement and 1100cc Forced Induction Displacement (up to 6 PSI max boos) or 950 cc (with 8 PSI max boost).
Note: At the first round of the World Series, a mistranslation between languages caused Pro Am Ski Modified to be run using Ski Superstock rules. As a result, IJSBA will run this class as Pro Am Ski Superstock at the World Finals.
Note: IJSBA announced that Ski Limited would be eliminating Ski Limited save for a classic 2 Stroke Ski Limited. In 2018, Mod Lites was created as a replacement for Limited Class. At the first round of the World Series, Expert Ski Limited was added to the program. This class was added as a combination of Two Stroke Limited Ski and Stock 1500 SXR. This same class will be run at the 2019 World Finals with the 1500 SXR allowed. As such, the displacement allowance is lifted to 1500cc for a naturally aspirated four stroke only. This is the same rule hybrid as Pro Am Womens’ Ski.
