I have raced F18s, Tornadoes, A Class, Tapian 4.9s and F16s (modified 4.9s). You barley notice the difference 20kg makes to a boat on land or water,
An extra 20kg will be notice by the manufactures and eventualy the customers back pocket. It will also reflect in fleet numbers as more manufactures climb on board.
While you are at it, try to get the Tornado class to up the weight by 20kg.
