2 engines or 1

Hi,
Is it better to have two 125HP engines or one 250HP? On a 7+ rib.

One 250 - less drag and better on fuel - carry a small 9hp backup engine.

Thanks Codprawn,

And

that makes 2-0. Actually, 3-0 because I was already along the lines of codprawn's thinking, but needed opinions from you guys.

However the other side of the argument is 2 proper sized engines (with completely independent battery and fuel systems) will be better if one engine ever dies than trudging home under a small aux. But you need to balance that against the higher purchase cost, reduced "effective total power", higher servicing cost, expense of making all fuel/electrics independent (so it is a true backup). Would you rather have 5% or 50% of your power if you need to travel 20 miles back to port, or tackle a tricky tidal race in nasty weather?

In terms of maneuverability, in harbour, twins should help (?) but a single on a 7.5m boat should be fine.

I'm not trying to sway you towards twins - just ensure you have both sides of the argument.

Appreciate that. A fair assessment of the possibilities I think.

Hi Rupert, I have followed a few of your boat buying threads and it has only just occurred to me that you should probably come and spend a day here in Alderney. There are lots of boats like the ones you are pondering, many of which we could have a run out in.

Let me know.

I'd love to do that when I get back to the Channel Islands. I might even invest in 15% of your company whilst I'm there
Seriously, I am away on work at the moment.
Why don't you send me e-mails of those boats if you have seen what I am looking for? I am only interested in cabined or canopy boats, however.

Cheers,
rupert.

Sounds good about the fresh investment, we have some exciting stuff going on at the moment.

None of the boats I had in mind were a hard sell, nor ideal for what you want. But I know that you can come here and compare a single engined RIB to a twin, have a look around a Redbay, plus try out a few other combinations of the good/bad/ugly that might help you decide.



Mind you, there is always the Boat Show next month!
