Do Multihullers Ever go Back?

I dont think you would go back.

I would be ashamed to be seen sailing that "thing". It is very UGLY

[robert sailor]

OK I'll bite! If that is your view of ugly what do you think of the appearance of the new Lagoons.

We love our little Hobie Tandem Island "tri" for day sailing.

GRAMMAR POLICE ALERT.

I may have implied something but you are the one that inferred something from what I implied.

Your point about pivoting on a fixed keel is well taken. But what I was trying to get across is that if a boat has twin screws (fixed keel or daggerboard/centerboard) you can put one engine in reverse and the other in forward and it will pivot but even if you have a fixed keel tri or monohull with a single screw it is hard to get it to turn as sharply as a boat with two screws.

no comparison in slow speed maneuvering. We can turn our boat in 360 degrees within about a length and a half.

And if one engine quits....we're still in business.

Many monohulls that made that transat with 40/43 feet have a total diesel tankage of about 150L. I am talking about performance cruisers, but even main market big production cruisers (the ones in bigger number) have not much more. For instance a Bavaria 40 has 210L, a Bavaria 46 the same, a Jeanneau 439 has 200L. Normally they all can have an extra deposit (option) with more 100L but even so it is way short of the over 600L that 43Ft cat (a production one) has of tankage.

You can see that difference looking for instance to a Lagoon 421 that has standard 600L of diesel tankage (more than the double of a similar sized mass production monohull cruiser) or the 450 that has standard a diesel tankage of 1000L.

Ah, so you mention that the slowest boats in the multi fleet actually DO have respectable tankage. Wonder if that has anything to do with their poor performance? How about the tankage on some of the multis which actually go fast?

Is it possible to design a cat that has good tankage and good speed? I suspect you have to get into the longer waterlines to acheive this.

Exactly. And if we stick to the usual calculus of comparing a 60' mono to a 45' cat, the tankage discrepancy becomes even clearer. The cat is both shorter waterline and much less load carrying capacity.

The other factor is performance under sail. I've seen power cats with huge tanks. Wonder how one would sail if you put a rig on it?

Would a cat with good sailing speed need good tankage.

You have one of the Catamarans that intrigue me.
I confess to never having seen a Catalac 12. I have read all I can on the web, and there is precious little.
I have sailed on an 8, 9, and been aboard a10.

I like the 'feel' of the 8 better than the 9 in seas, and the one I sailed on had an outboard rather than twin diesels. I liked the 9 for the extra room, but not sure if I like the helm position. I never got to sail the 10, and was a little leary of all the glass that would need re sealing.

But the 12 seems like it is 'proper' workmanlike offshore Catamaran.

If at some stage, you feel like doing a walkthrough on your vessel with a video camera, I for one would appreciate it very much. It is a rare animal and its legacy should be preserved if possible.

Thanks
Gary.

It would if there was no wind... seem to vaguely remember wild speculations when a Lagoon 440 was only managing around 25-35 miles/ day for a coupla 3 days...

Ah, but is a Lagoon 440 a good sailing cat?

Well.. this one was doing between 165-205nm/day in winds from 15-25kts.. till I turned N and started hitting light and variable winds.. depends on how fast you need..

Definitely not a performance cat

It's just about at it's lowest point on attractiveness right now. We've been tearing out electronics, old equipment, and the interior. surprisingly enough, just as the old girl was looking her worst, we had her appraised for Customs value, and imported her into the Turks and Caicos Islands yesterday while the boat was at it's lowest resale value.

Now, begins the turnaround.

We'll be putting the sails back on today, picking up all the clutter, re-attaching the hanging light fixtures, cleaning some things up, and hope to be out sailing by the weekend.

There are photos of this boat on our trip down from Florida in 2012, but they're on our blog. I don't want to be one of those blog floggers, but if you do want to see those email me and I'll send you a link to those Catalac specific posts.

We'll definitely be posting photos as we progress. We are not returning this to the traditional interior, for example. I'm in the process of picking AIS, comms, GPS/trackplotter, and radar to replace everything fried by lightning on our way home with it. Nice shakedown, huh?
