Q-Sporthydro

Hello, I´m new in this forum and first I want to introduce myself a bit. My name is Volker Schneider and I´m from Germany near Heidelberg. I´m 48 years old and fast electric boats are my hobby.. 
I want to build a Q-Sporthydro hull which complies to the Namba/Impba Rules.
My question is, if there is a minimum tub width in this class?
In the General Namba rules, there are minimum tub widths in the boat specifications for the Sport 12,21 ….classes, but I can´t find such measurements in the hull specifications in the electric rules..
I hope you understand my English.. 

Hi Volker,

You will find the information on J2 & J7 here for the IMPBA.

Hello Volker and welcome to the OSE Forum.

On the NAMBA side it is a little more complex for the sport hydroplane rules.
See section 28.E.1 in http://namba.com/content/library/rul...a_rulebook.pdf
Pay particular close attention to section C (28.E.1.C) for Hull Specifications.
