depends on the conditions I guess

you can paddle a RIB in ideal conditions (no sea and no wind) but you won't get far going in to a headwind

I would probably think it was a bit small to get any real movement but as you have it already then ask the question on is it betetr than paddling.....
I bet a 2.5hp outboard can move a 6m rib better and faster than paddling, even in calm conditions......

My 5.1m has a 2.5hp, and I've tried it in a very strong head wind, up river though so I wasnt trying to tackle any waves of any consequence, it wasnt much cop to be honest, it was difficult to steer as the wind took you and I made very little real progress, HOWEVER, I believe that if need be it would keep me off rocks and at the very least hold my position 'til help arrived if I needed it and I'd rather do that with an engine than a paddle

much the same could be said of my 6hp though - a 20kt crosswind makes the thing nigh on impossible to steer in any sort of sensible direction!

You tend to forget how much a RIB weighs till you try and manoevre it with a strimmer engine

i have a humber 6.3 inboard with a yamaha 4hp 4 stroke on the back. The boat will move at 4kn no wind no tide, but only 1.5 /2 kn with 2kn tide no wind. the turning circle is brilliant (on a sixpence) with leg up. Had to use it for real a cupple of weeks ago as water hose went on engin, yam started 2nd or 3rd pull after 3months no use but fuel in auxilery tank was was going off so kept cutting out, changed fuel now works ok

But if you want to be extra safe have you ever thought both of your engines might pack up then you'll need an auxiliery !

Especialy if its the fuel to blame and both engines feed off one tank. Thats why we run the aux off a seperate 25l just in case.
