chine walk
 

anyone know how to cure chine walk at 70 mph. on a sting ray 698 svx?

try different styles of props

Control it via steering input, but if there is a lot of slack in your steering system then it is harder.

original prop was a 23p mirage 3 blade, now have 24p 4 blade bravo one. this made no difference with chine walk problem, only performance. has better low end and mid range but lost 2 mph on top end

steering feels tight. I have considered external hydraulic steering or/ and trim tabs, but I feel that maybe it has more to do with hull design?

I had the same problem with our Checkmate 259 Convincor. Now spinning a B1 labbed prop with full hydaulic steering and HP tabs 22 inch in length the chine walk can be eliminated. At speeds around 70 GPS the boat can still chine walk a little with tabs all the way up. I can drop the tabs just a touch and the boat settles right down. The problem is I will loose 2mph! To eliminate the chine walk it seems you just need a little more wetted surface which in return scrubs speed. I have thought about adding more power to this hull (460 now) to get into the 80 plus mph range. I know the hull can handle it the way it is currently setup however it may not do it as efficiently as some other hulls similar in size ie a 26 Eliminator Daytona. I think I am going to sell the boat and buy a hull that was designed to run fast up top. I am sure there will be trade offs of course but such is life.

I have considered selling and upgrading as well.The problem is I want the best of both worlds.I have A family that likes to ski and tube and I want to be able to fly down the lake at 80+ mph.The stingray 23' cuddy with 502mpi does A good job at pretty much doing both, but naturally I want more.Thought about A baja 25ol, but it does nt sound like they go much faster without allot of mods,so maybe just keep what I have and put money into it.which
I don't mind doing as long as the hull can handle it.

Ever heard of water skiing or tubing behind A CAT??

Our 202 stinger does it at about 65/70 mph. We just hold on drive thru it then it takes it's set on the v and it's good to go.Takes some driving though.Be careful .If it is to bad ,it's not safe.JOHN

A 23 Stingray is not made to go 80.

I have heard mixed reviews about water skiing and tubing behind a 26 Daytona. Hopefully I will be able to answer this question myself in about 6 months.

One more thing, I have a 2000 Checkmate 259 Convincor for sale in the classifieds for 30K. I think it is a lot of boat for the money. If you are looking for a Baja 25 Outlaw I would take the time to look at this boat. It will only do about 70 GPS give or take 2mph on load and water conditions but this boat is very clean. The speedo will read high 70s so your passengers think they are in a 80mph boat!:eek:

23cuddy with stock 502 = 80mph?
thats one fast hull!

I had a 22" with 454, peanut heads, stock exhaust, and q-jet ran 70 on gps.

you can learn to drive with chinewalk, by sawing the wheel back and forth until you match the walk then the hull is straight your hand is moving the wheel. I did that with my 24ol when running high 70s to mid 80s. I had add on hyd steering and not full up to the dash which is better. and might stop all the walk. art
