You will need to translate but nowaday shouldn't be an issue.

Thanks for the information. This is one of my frustrations. Despite the reassuring indicator of Comar having sold hundreds of Comet yachts, it did not prove to be reliable in this case.

And it's my issue as well. When I visited them I had a very thorough tour while they were building Hull#2 (so probably more than one year ago .... time flies). The owner went through all processes and choices they made and very transparently declared some issues with hull#1. The way details were explained and choices compared demonstrated a huge amount of knowledge as a building yard but at the same time they acknowledged the fact that they were yet not "experts" in multihulls (despite a good number of C-CAT 37 sold worldwide). So, all in all a great visit and a humble approach which I appreciated. Now, I fully agree with your view on the C-CAT 48. It is in my opinion, as often happens (e.g. Outremer 45), a 45 foot project transformed in 48 and you can see it especially for the space distribution. It is also a great performance cat (I saw videos that stated that) and thus I can imagine pretty sensitive to weight as most of them. Still a very well thought cat and a niche alternative to others. Your feedback is now concerning. I will go ahead keeping an eye on them but also weighting everything based on your feedback. Appreciated your willing to share in such a balanced way.

Interesting but far from being a complete story of former great Name.

Wish them to return back on track, or more precisely, set proper place within multihull sector.

Aa far as can expect first C48 was basically built on S46 molds.
But it really does not matter and I do wish C-Cat to keep on developing without repearting their bad experience of former COMAR/COMET.

former COMAR/COMET.

What is the S46?

This long story began in 2011-2012 known to a limited number of people when Slyder-46 project started. In 2013 they changed a bit its initial design due to switching over to another designer. Later on the project was renamed to Slyder- 47 and in 2014 S47#1 was demoulded in Italy. In 2017 (or even in 2016) the project changed its hands, but S46/47molds were left in Italy. Untill ...

I was testing the Slyder 4901 MARQUIS, and now that you mentioned it, the layout, proportions, and concept have a lot in common with the C-Cat 48 #1. It was my impression that similar to the C-Cat 48 #1, the Slyder 4901 uses some heavy components. During my visits to Comar, it seemed that they developed or modified their moulds and tried to use as many self-manufactured components as possible.

AFAIK S4901 was built in China under German management. I do not know if they place any S47 ideas into their new 49-ft project.

C48 exterior lines differ from S47 by short swim platform added. May expect that "transom extention" to S47 molds was made by Comar.

The C-Cat 48 is very sensitive to weight due to its narrow hulls and size. It appears that the following hulls had to be made significantly lighter by changing the top structure material to carbon.

The power specifications are somewhat unclear to me. The chosen Lombardini engines are not very common, so it is difficult to assess their reliability. However, I do appreciate the shaft design instead of sail drives. The fuel tanks are relatively small, in my opinion. This boat seems more suitable for medium-range cruising with careful loading rather than for live-aboard ocean-crossing voyages.

Reliability of Lombardini shouldn’t be a major concern, I have installed and tested lots of these in non marine applications. They have a very good reputation. Why wouldn’t you expect to find an Italian engine in an Italian boat.

I was under the impression that Slyder cats were aluminium am I wrong?

I did not claim that Lombardini engines are unreliable; I simply mentioned that I do not know.
If you have non-marine installations or spend your sailing time near major hubs in first-world countries, you can likely source parts and support without issue. My bias comes from spending five years of catamaran sailing off-grid in places like East Africa and the Indian Ocean. While parts for Yanmar or Kubota were always available, Kohler (the owner of Lombardini) had a presence only in South Africa. Even when I got to Europe, their support and warranty services were lacking.

I understand that an Italian shipyard would opt for Italian parts, and their choices are likely based on their experience, integrity, and cost considerations. I had a very good experience with Italian brands such as Harken, Schenker and Frigomar and had less favourable experiences with Isotherm and Quick. If I were specifying a semi-custom build again, the country of origin would not be the primary consideration.
