Sirena 68 v Magellano 66

AFAIK Sirena used to build the Magellano 43, and probably did some of the 50s (but this is not confirmed). Then the collaboration was broken.

Sirena is more voluminous, Magellano is a better performing yacht.
Can't remember range numbers of both, but Magellano 66 has 2 x Man 850hp and 4500 liters capacity weighting 47t with 5.5 meters beam.
Sirena is longer and wider 5.9 m weighs 47t (the same) and has twin Volvo 1000hp for 5250 l.
These number are all in favor of the Magellano also in performing and in real World might give you about 10%.

Since they weigh the same I would say they are similar. On paper Azimut looks stronger, also because they had thicker GRP to the normal Azimut.

I considered a Magellano but was massively underwhelmed by the space it offers both inside and out. The fly is tiny given the sze of the boat. Sirena in a different league space wise even if I don't particularly like the finish. Hard to put my finger on what exactly it is but I feel it is lacking depth of quality if that makes sense.

"Production boat" is certainly one way to describe it. The Sirena is just a bit bland in comparison and lacking finesse. It tries to look like an italian design but doesn't quite manage. Having said all that, I didn't get out on the water with either of them! So my feedback is soley on looks and perceived quality.

If you are not set on shafts only, have you looked at Absolute Navettas? This is what I am now ending up with. Different league to both of them in terms perceived quality.
