High speed turn with 9m. rib

What is the normal way for a 9 m. rib with two outboards to handle if thrown into a tight turn doing 50 knots on flat water? Is it to slide sideways and suddely grab the water hard and then bouce to the other side throwing everybody in the water?

silly question but are you trimming the engine in before the turn or leaving it up, if up you are going to lose grip and slide and bounce as you suggest

I always go with the engines leveled on the middle, read from the meter, exept when accelerating.

try trimming in more ie fully down for tight turns or maybe you need trim tabs as well to get her tracking better without seeing pictures or having a go its a bit of guess work really
any near you with similar setup or can you get access to manufacturer for advice
sorry not much help

I'm not sure I'd want to throw it into a turn at 50mph with full down trim. Depends on the boat but I'd take care.

Agreed. You could quite easily end up with the stern overtaking the bow rather rapidly!

The only reason to do this is in an emergancy or for the RCD which is built up to slowly and should only be tried by a very experienced skipper!


If you're going to do it I agree with JW and JK - a bit of trim will give the bow less chance to hook and throw everyone out!
More trim also helps the boat bank a bit although this is dependant on the hull design.

It stands for Recreational Craft Directive and is what you have to go through to get your CE mark so you can sell any boat in the EU.

Hope that explains it all,
