Anybody running a Rogers hull or bottom with a droop? if so how does it run.. I am being told by a few people that i screwed up by installing a droop and cutting the ride plate.. I guess from what they are saying the Bahner has a Rogers bottom to it ??? and the droop will cause it to porpoise and slow it down??
Anybody

Incorrect. Rogers work great with a droop. This one is very near 100 with a droop.

You need to finish the boat and get it on the water.
Then you can start trying different things. At this point you can take information, get upset and start making changes without even knowing if what you have is good or not.

we run a droop on the cj410 rogers with a 2 degree up wedge . i installed it this way after talking to roger wyman when i first set the boat up to race. seems to work just fine.

This is the same set up im running , but my pump has a 4 degree down angle..

Words of wisdom.. My whole intention is to run what i have installed, just because it dont work for some dont mean it wont work for me... Im not tearing apart the Bahner!!! No phuckin way... This might sound weird , but i love that boat :'( I have put my life into this pile not to mention my wallet ;)
Was just looking for some Rogers owners/drivers and see what they say..
Thanks very much to all who have replied......I can see clearly now, the rain has gone ;D

Here are a couple of responses to the Bahner, and the reason why i was asking. I do appreciate there input as i do everyones...But from what im told you cant set up every boat the same, so we will see here shortly how she will run.. and 2nd post i only have a 2deg up wedge so its 6degrees up angle ???

wow, it's looking real good so far. Since you have the Roger's bottom on it, you will probably find out it will like a 2ยบ down wedge instead of going up with it. With it that far up, it's gonna bury that transom quite a bit and slow it way down.
I've got the same bottom on my boat with a similar set-up.

It looks like you've added a droop, which will change everything. The droop gives you an additional 8 degrees(typical droop angle) up angle. So, it looks like you have a 4 degree up wedge and 8 degree droop, that's 12 degrees up. Subtract the 4 degrees down that most pumps are mounted and you're still looking at 8 degrees up angle. That will make a helluva rooster tail, but might not be so good for top speed and will most likely cause some porpoising.
The set up will take some time. Each change will affect the speed and ride of the boat. It will be up to you to decide what works best for you.
And if I were you, I'd ditch the rudder completely. The only thing they are good for is to cause a massive drag.

Now that i take another look at the pic........I say the pump is at a 4 degree angle it will be fine
