CG vs. Drive Angle

[NitroVal]

What is more important when it comes to properly setting up a boat? I was thinking of moving the battery box forward on my EKOS to keep as level of a drive angle as possible for the most speed without having blowover problems. Right now the CG sits about 228.6mm (9") from the transom on a 34" hull

Im interested in this as well as Im also trying to dial in a cat. Not a EKOS. I was pondering that same question this afternoon.

Only input I can share thus far, is measure c.o.g. from the back of the sponsons, NOT THE BACK OF THE BOAT. If it is 9" from the back of the sponsons, your at 26%. If memory serves, you want between 28 and 34? There are A LOT of guys on here running cats that have such a wealth of info it just blows my mind. They will set you (and I) straight.

Yea, thats what I meant was the back of the sponson. I wanst sure what to call since these cats have that platform in the back

CG is more important then you can play around with strutt angle

I think both are important. You have to find a balance between the two.

Here is an interesting article. http://findarticles.com/p/articles/m...6/ai_n8865020/

and another.. http://findarticles.com/p/articles/m...=rbxcra.2.a.22
The second article was written by Jay Turner (Fluid) on this forum.

There are alot of interesting articles on the internet. Use them as a reference. But experiment with your own setup as it varies. What may work for one boater may be disastrous for another.

C of G is very important.

Depending on type of hull and location of your equipment,

Calm water conditions = 26 % of hull length - Your hull = 221mm
Medium water conditions = 28 % of hull length - Your hull = 238mm
Rough water conditions = 30 to 32 % of hull length - Your hull =255 to 272mm

You can mark the inside of your hull with these measurements and adjust battery position in the boat to suit the water conditions.

I like to keep most of the bulk weight close to C of G. I found my boats settle down faster once unstable.

Hope this helps,
Rob.
