Has anyone got a twin engined setup on a 5.5m rib?

What speeds do u reach etc

It all depends on the hull, engine/prop size.


I know its not 5.5 bit I had a 1996 Northcraft 5.8m, twin Mariner 60's. Circa 32knts.


Didn't like them, made the boat feel lardy at the back end, fuel was eye watering too if you were pushing on a bit, something like 1.2 litres/mile. You are also double everything for servicing, it makes a difference.


Swapped them out for a single Suzuki df140, different boat, light, responsive and fuel consumption was far more acceptable, 0.8 litres/mile

100% Agree ....unless you're poodleing around a Harbour and or working at displacement speeds (and then why would you go for a twin out of choice?) a twin set up will all but kill the fun on a RIB of THAT size ...plus you'll have all the disadvantages and expense Alan has already mentioned.
Go for a decent sized reliable Single... you'll enjoy it a lot more...cost much less...and easier to sell if you want to upgrade in the future
