Below are logo links
to other U.S.
PWC Racing Series.

This page contains specific race class rules that are in addition to regular U.S. WATERCROSS Racing regulations.
 We are offering some one of a kind U.S. Watercross race classes that do not have specific oversight. We will address these race class rules here on this web site.
 The idea is to offer a outlet for owners of the some of the orginal Stand Up PWC (Vintage Ski) to race them in a safe and organized environment.

 U.S. Watercross
No-Contact Racing Rules.

 

We recognize the fact that, especially with Regional PWC racing, there is a sizable group of competitors (and potential competitors) who want to enjoy the thrill of racing, but want to feel as safe as possible while doing so.

After all, we aren't racing at Regional events to make a living. We all have jobs and families to return to on Monday, right?

Of course, every Great Lakes Watercross racing event includes a pre-race rider’s meeting where safety is stressed, but we wanted to take safety a step further for some of the racing classes by designating certain classes as “No-Contact”.

Now, this certainly does not mean that the other “standard” classes promote contact amongst competitors, not at all.
It means that all “standard” classes will maintain a racing standard similar to what any competitor might experience anywhere else in the country.
As for the racing classes now designated as “No-Contact”, the following standards will be applied:

 

 

1)         All competitors are expected to start each race with the mindset

that avoiding all contact with other competitors is a primary goal,

and secondary to nothing else. Just like you are expected to line up

wearing a helmet and a PFD, you are expected to line up with this

mindset.

 

2)         All competitors are expected to maintain a safe distance between

other competitors that is large enough to allow them to avoid contact.

This may vary some depending on the skill of each competitor, but the

basic rule is that YOU need to leave enough space for YOU to avoid

contact with THEM.

 

3)         All competitors are expected to only attempt clean passes with NO

contact. If you aren't 100% convinced that the pass you’re about to

try can be pulled off cleanly, then DO NOT attempt it.

 

4)         Contact with lapped racers is 100% forbidden. If you’re good

enough to lap another racer, then you’re good enough to pass them

cleanly. Contact with a lapped racer is grounds for immediate

disqualification and further sanctions.

 

5)         Holeshots are typically the most stressful, congested, and

dangerous part of a race. Therefore, any racer who prefers to delay

their start a bit is welcomed and encouraged to do so. Sometimes

waiting for the other racers to clear the starting gate first before

proceeding will allow less-confident racers to more gradually become

comfortable with the whole process. After all, this is still racing,

and it happens fast. If you prefer to delay your start, please make

sure your holder(s) know this in advance. Also, it is a good idea to

let the racers and holders on either side of you know this as well

during the staging process.

 

6)         “No-Contact" racing is still NOT a guarantee that contact won’t

happen. It is merely a set of standards to attract like-minded racers

who want to have fun while prioritizing safety. We hope this type of

"mind set" will greatly reduce and maybe even eliminate the chances

of contact happening.
