How fast can you go before "wobbling"?

[joakimhansson]

In size between 23-29 foot. I heard that the swedish rib, ribunlimited 700 has big problem over 40-42 knot. Ok, the boat is very light but...who want?

Drive through it, see whats on the other side, thinkin "wobbling" means chinewalk , as your skill grows you will automaticly compansate for the chinewalk, some setup addjustment may help as well.

Mine doesn't wobble!

I have a RIB Unlimited 700 with a Yamaha 115 and have almost never experienced "wobble" maybe a tendency with just myself onboard low fuel load and outboard trimmed out a long way.........
With a clean bottom I've seen 47 Knots on the GPS.

My old Avon Searider with a mercury 75 I had in Plymouth many years ago used to do real "tank slappers"

In my view 'chinewalk' is a badly set-up boat. I wouldn't want to power through it, i'd not want the boat in the first place. I drove a Nouvorania 5.5 with a 90 Honda on it that 'walked' all over the place it was not nice.

"In my view 'chinewalk' is a badly set-up boat."
not so, some setup can contribute to the walk, but most of it is Driver Skill.
seen it many times, the hull be slapin left and right like a door flapin in the wind, a skilled driver reach over from the passenger side with one hand and it disapears.

Nick, Is the unlimited good even in sharp corners?

[Nicksweden]

Excellent in fast corners, I had the outboard mounted very high up a couple of years ago, for higher top speed, which has the effect of loosing some grip in sharp turns. With the outboard mounted in the standard poistion as I have now there is no problem.
By the way, I have changed from the standard 3 bladed Yamaha S/S propeller
to a four bladed S/S prop this gives better grip, useful when it's a bit choppy.

Funnily enuff I used to get 42 knots GPS out of my Searider 4.7 and that chined badly at around 35 and it was down to my understanding of the bots handling,

but I was driving a Ribtec at 44 knots the other day and I did not want to take the chining any further but it did have an Aux on the transom.
