-Here are my thoughts, these items are usually better hashed out in person first of all at a meeting.
-Boat racing has gone sideways trying to introduce and spec the heck outta it (look at the US and canada previously, history can repeat)
-Boat count as pointed out is key, I'm sure if we had 11-12 boats we would heavily consider splitting, but not at 10, sorry, there are no classes any where in the world that split at any less than 11-12, I would hate to see it turn boats away but this is a fact of racing and it is what it is, this has only been a problem once, usually fewer boats by nature... if there are more than great we split, was just a number we ended up with, get your friends out!!! This won't change so not worth discussion.
-Rough water is what this class is, they are V-bottoms cutting a 4' swath in the water, dunnville is the worst with the current and wind etc, there are many other classes if you don't like rough, not being a weeener, just saying thats the truth, its always been this way, part of the excitement and talent of the class!!!
- You already have two classes, I suggest if you want a spec class use 49CI (750) and use that as a starter/spec class for those who want one and leave 56 (850) for those who want to play and blow stuff up!!!
-The success of this class is based on its openess as most are lake boats as well and guys like to play...., so play! If you want to ban SST60 motors than get together with everyone and talk about it, agree that you will stick to a certain area and go for it. I'm sure gun will still build a dope 56 to come out with, same with gig... than its on.
-No race fuel will limit who is running high comp
Get a fuel tester to test for octane/additives and set a max. No one can run unfair high comp at 91 octane
