what happens if one of the engines breaks down, can you still sail decently with the other engine (considering propellors in twin setup have a different pitch) Give a twin 30 the same speed as a single 60PK?
When I specked my Hurricane 590 many years ago, I was going to go with twin 70's vs a single 150. Almost everyone I spoke with urged me to use the single.... better mileage, less weight, higher speed, less initial cost, less maintenance cost. The ONLY advantage to twins is the redundancy. This isn't something to be be overlooked depending on your application. Someone also pointed out that many "engine problems" are related to water in the fuel as well, so unless you have separate fuel systems, and fill them at separate times, some of the advantage of twins is lost. To answer your question though, generally,, boats will still run reasonably well with one engine down.
Dougal Short thanks for your information. Never thought about water in the fuel, what can eliminate the benefit of a twin setup. I just found this article about twin vs single, interesting too: i.stuff.co.nz/sport/boating/68923003/
Yes, you can still navigate with one engine. Indeed it won't be as optimal as if you had both, but it allows to recover the boat safely. You'll reach higher speed with single 60hp but you'll have better torque with Twin 30hp.
Wow! Twin tillers! First time I've seen that.

Nice, it must be the first time to see a low power twin setup.
