Certainly always been the standard to do so here on CF. Because they cost about the same. You know this, it's mentioned often. In this thread too.

And he can compare it to my build, 35' mono and 1.5t tankage for diesel. Not the fastest boat in the fleet but got no hurry to get to busy marinas either..

Well, been in a bad weather a couple of times. The first vid was just a mild gale, not much to talk about waves. The second one, maybe the wind was about 25m/s (50knots) just breaking the storm strength but the sea was just starting to build up, 15' I reckon. Nasty if going any other direction but not DW. Third reef in the mainsail with a mono..

I think you hit the nail on the head. If your boat is slow you carry large quantities of diesel as you know you will only sail 10% of the time. If you have a fast boat, no need for a lot of fuel. I like the fast boat. Better on the environment , the pocket book and peace of mind.

Well guys.
Its time for me to leave this discussion.

When its getting into a pissing contest about cats vs monos with a distinct lack of humour.........

For those that dont know... VIDEO does not really show the full extent of wave height due to linear lack of perspective and some other technical stuff.

It dont matter, the weather is bad enough for me and whatever vessel Im in, I might go downwind for a while and retrace.... but Im a wimp that way.

We all love boats, and the merits of one hull or more is particularised by the application we have for it. the types will interchange in most situations, and be better in some.

Its down to preference in the end. I love sub 30foot bilge keelers, and in the mono world that is considered 'less' of a boat lolol... I guess I cant win regardless. But I do have a supreme fondness for the Med on a Catamaran.

1.00 am here in the U,K. I wish you all a good night and hope to discuss another topic at another time.

You guys can choose to think a cat is the be all end all for all conditions, with no drawbacks whatsoever to consider, and I know you will. But for the undecided out there, the truth should be known...

I find this humorous. The mono guys love coming over to the multi forum and trashing the seaworthiness of our boats. I don't know about the other multihullers but I hardly ever go to the monohull forum. Even during the once a week report of another mono sinking I leave it alone. Maybe the multihull crowd should feel more comfortable and visit the mono forum more often, possibly making some obnoxious comments concerning the seaworthiness of their boats? Nah, would take up to much time and let's face it we are pretty secure in our choice on boat:-)

There are a couple of folks who seem to spend some time looking for a chance to have a dig at mono's from the multi brigade.

It all seems so pointless to me. If you are secure in your choice then it does not matter a sod if somebody else does not like it. If you are insecure about it then you better change it because your life is going to be a misery defending it against all the world.

I think the whole debate needs a bit more humour and light. The same old serious "mine's right and yours is wrong" stuff is old hat and merely proves which side has the most sensitive supporters, nothing else

Coops.

Yes multihulls are more expensive but I don't think it will be a reason to compare the tankage of bigger sailboats with the one of smaller ones. You have the money for one or not, the same way you have the money for a new boat or have not (and have to buy an used one). And if you have plenty of money that would not mean that you would want to buy a 100ft or the bigger boat around.

Sure, being more expensive is a big disadvantage in what regards catamarans as it is paying more money on a marina and on maintenance, or needing a bigger boat to have the same seaworthiness, the non re-righting ability are just some of the disadvantages of that type of sailboat, nor a reason to compare a smaller boat with a bigger boat in what regards tankage.

Cruisers & Sailing Forums > The Fleet > General Sailing Forum
> Do Multihullers Ever go Back

Yes, specially humorous since this thread is not on multihull forum but on the General sailing forum and his title and content is more than a bit provocative to the ones that prefer monohulls: It is implied that multihulls are a better option for cruising than monohulls since most sailors that pass to multihulls do not come back. Of course the vast majority that pass to monohulls do that not for sailing reasons but for space reasons and the condo cats largely dominate the market in a proportion of 10 to one or more.

It is even more funny since the one that started this thread is one of that small minority that own a true performance cat. Probably the ones that own performance multihulls have more in common with the ones that own performance monohulls than with the ones that own condo cats and that makes the idea of this thread an unhappy one.

The Voyage 440 is a performance cat? I guess on par with those Deans! We certainly have a different idea of what constitutes "performance" in regard to catamarans. I'm not knocking the Voyage and do not consider our boat a performance design either.

44CC's boat, on the other hand, does sneak onto that side of the line.

And yes, I do have experience sailing Voyages (I think this type of disclaimer should be considered important on this thread!).

You are discussing this one thread and I agree with what you say. But in general I believe in what I said is true. I think the majority of the people that switch from mono to multi think they're going to gain both speed and space. But like you said the majority buy the condo cats and get the space but realize no gain in performance.
