How fast do you think 29 hull can handel.

The hull will start chine walking at 80. I found that out the second time out with the boat, needless to say I backed off. (I was up there in Jax boating last March in 60 degree air and the boat ran like a raped ape)......I'm told if you drive through it by reacting with the steering, things should calm down around 84 or so if you have the power to get there. I've spoken with the guy who owns the 29' former speed record holder. His boat runs close to 90 and he says it's one scary ride!!!

I am just looking for something to get that rush.I think it would
be awsome to run it up into the 90 once in while.I wonder if
bigger tabs would help chine walk?

chine walk
 
Liquid,i have 380 plane's on my boat,use them just to help git on plane or in the rough stuff,good luck.

I do not know much about singles but I just got back from running my 29 with twin 500 EFI's at 93 MPH and it ran fine. I run about 1/2 down on the tabs to maintain control and then raise them ONLY when it is calm enough to push it to its limit. My 502's are pushing 575 HP and 625 Touque. But as I have posted earlier I have faster steering to help solve the problem faster. Roger
