View Full Version : Spec 12 cell Mono or Offshore?
02-24-2002, 10:19 AM
Here's something else to consider. Assuming that the original 12 cell spec motor class (12 cell spce mono) continues to be popular this year, do we keep it as strictly a mono class or do we throw it open to being an offshore class as it's being held down south (USA). Essentially the difference is whether stepped monos and cats are allowed. Defined as an Offshore class, they would be - as a mono class, they would not.

I would prefer the Offshore...take it to 4 minutes, introduce a left hand turn...and open it up to other hull types. It is a tranferrable class and it was very competitive in Michigan. However, for club racing we should make it a "spec" offshore and fix the motor to a 8.4V BB...discussion please guys!

I am beginning to get the itch to begin...
My first project is to get the twitch out of you 12 cell mono. That twitch has to be removed...do you have any thoughts on how to correct it. I have a deep rudder, I have tried a deeper turn fin, I have moved the CG. Do you think I should cut through the front bulkhead and move CG even more forward.
It seems like the boat is about to hook and spin, inatead it darts across a couple of lanes and by the time we corral it, we have had to back out, invariably losing position...

Just a couple of thoughts. It's always so difficult to diagnose "over the phone". Make sure the aft bottom sheeting does not have a cup in it (just ahead of the transom). Is there not enough hull in the water to provide directional stability? Is just the turn fin/prop/rudder in the water causing it to over-respond to things like wake, waves, etc.? Maybe there is too much turn fin. (?) Is the rudder jacking up the transom in a hard turn? (rudder lift). Do you use trim plates, I can't remember? Can they be causing instability in the turns?
It sure sounds like a problem that may some more of testing of changes to track down.
Right now I only have a 9.6 Neo, so I would like to see that motor "spec" also. I vote yes for 4 min and left turns but I am not sure cats and stepped hulls should be legal with the monos.

I can go with the 9.6V Neo, we already allow stepped hulls, the tunnels wouldn't be a real issue at our club...nobody runs them. Of course someone could build one if they chose to. I was thinking of one, but I am probably going to stick with the Forrester Mono...if I can solve the "mono twitch" problem I am experiencing right now.
