It's hard to understand why every mono/multi debate comes to the fact that wether the mono is better off when knocked down 180 degrees or a multi going turtle. None of them are a pleasant experiences but thanks God, these are very extreme cases. But hitting something is much more likely and under these conditions I would prefer to b e on a boat with a positive buoyoncy, hence a multi. A small hole in a mono is enough to send you down in a matter of minutes, while I have seen a multi (Athena 38) with 1 m hole in one hull still floating.. I sailed all kind of monos and raced with them, it's probably more fun to heel for couple of hours but not for long passages. You can also learn sailing better on mono as get much more feedback from the boat.
All in all, there are times I like to be on mono or times I feel much more confident on catmaran. If I were to go above/below 40 lattitudes I'd rather be on a steel
60 ft mono. (and with competent crew..) I took my cat on my way to Caribbean
the 44ft cat with my wife and we could enjoy so far all the positive attribute of the cat: shollow waters, no rolling at anchor
, easy manoeuvring under power, watching movies in our fast passage
in the saloon
when it was cold and rough outside in the Med in December and above all with our wine bottle always on the table since Marmaris up to Guadaloupe
As far as the speed goes; I was only overtaken once; by a 80 ft super yatch near Bequia. I've read her speed on my AIS
as 14.8 kts when I was doing 11 kts..
Monos have two distinnctive advantage over cats: most people find their look much sexier than the cats and the helm
feedback.. One can also add the upwind ability but this is open debates; most of the modern cats (particularly the ones with daggerboards) are sailing upwind much better than many average cruising monos.
After all, we should accept that something good to us may not be so for others and I personaly respect everyones views when it comes to how to sail.
I have different opinions though for motor
