Re: 45' (or so) Performance Cruising Catamaran

Have you looked at the class 4 catamarans by O Yachts? They seem very customizable and oriented towards strength performance and safety. 46 foot fully equipped with dingy and Provisions what's coming out at just over eight tons. Utilization of a lot of carbon fiber to. I know nothing about them other than the intro video, but seems like a very well-made and fast catamaran.

I would also consider the Knysna 440 and upwards. I am a great supporter of the Angelo Lavranos designs

Re: 45' (or so) Performance Cruising Catamaran

What is the technical difference between a performance Cat and "Condomaran"?

Re: 45' (or so) Performance Cruising Catamaran

The Nautitech 47 has a lot to commend it. I've just done 20,000 miles over the last two years and find its design hard to fault.

The primary ones would be:

Waterline length/Hull Beam ratio.
Sail Area/Disp ratio.
Displacement/Length ratio.
Daggerboards v mini keels.

Re: 45' (or so) Performance Cruising Catamaran

work of art:

Blue water catamaran trip

I have inspected 4 years old one. Owner claiming 350 miles days. ROBUST is the word! Catanas and otehr above mentioned, cannot fit this league.

However, 350 miles days leave mark on boat.

Your quoted story sounds pretty reasonable and honest... and a nice boat as described. But your owner claiming 350 mile days is pretty hard to believe... that's AVERAGING just under 15 knots, and that's difficult to attain for those periods.

Re: 45' (or so) Performance Cruising Catamaran

350 is a stretch, but the Freydis is a great boat, one of the best

I find it difficult to understand with all the information now available, that people can still believe there is a performance differential between Daggerboard and mini keel boats that could be considered significant for a cruiser.

Try reading Tony Grangers article on this subject on his web site.

A small snippet here.............

"As the wind strength increases the fixed keels will typically operate much more efficiently and from personal experience the difference in performance between two similar cats -one with efficient fixed keels, the other with daggers - is minimal in 10 knots or more of breeze, and negligible in 15 knots and above."

Considering most cruisers motor in the light stuff, including our beloved 44c, who has motored past us on a couple of occasions ( possibly due to his unwillingness to fly a spinnaker / carry a spinnaker?) Its hard to understand where this great difference lies.

Soubise was THE Boat for me. Just about to order it but other things surfaced in life. 350Nm , read several blogs and have no reason to believe it is not true. They go real well in small winds, on pair with racing monos.

Designer of the boat has excellent articles regarding fixed keel vs draggerboard. Difference is indeed minimal. 1 degree or so. He made same boat with draggerboards and fixed and sure is authority on this.

One thing that is weak point of thin hulled cats is stability in storm. Got this from blogs.

No perfect boat.

Just curious, when and where did I "motor past" you? And what boat were you in?

Also I have absolutely no "unwillingness to fly a spinnaker / carry a spinnaker?" I have a reluctance to PAY for a spinnaker. I'd actually like one, but really can't afford one. If someone was willing to donate one I'd be happy to carry it and use it.

But in 27,000 miles we have encountered maybe one minikeel boat that could almost (but not quite) stay with us on a reach. Even though we do lack the specialised light wind sails.

And none that went close upwind. No doubt there are some out there, but we haven't encountered them.

Fact is, a minkeel boat will have more leeway upwind, (however slight the difference might be) and more drag downwind or reaching.
