DynaRig MotorSailer, ala Maltese Falcon

Pericles, no wonder women do not understand men, I would have been a pirate in another life, it really must have been a very adventurous time sailing around plundering wealth merchants. Today all we are allowed to do is go sailing still, but those times also will be limited if the dogooders have their ways, we would have to be licenced to go to sea, must have the manning, even if we want to sail solo or limited, have to wear hard hats, steel capped boots etc etc, "if it only saves one life"....oh please, let me go free.........

She is truely a woonderful little ship... great that someone would think outside the square, but put the money on the table too....that is the hard part.

 

Become a private contractor and apply for Letters of Marque from Congress.

Pericles

 

Sorry Pericles, can't find the "Dynarig not for sloop" article either. There have been at least three multiple page articles about Maltese Falcon in Yachting World and have got only one at home. I'm pretty, sure it was in YW but i can be wrong, i read a lot of magazines and many of them featured MF the past Year.

I will try to find it.

Included is the best paper on the Dyna rig application, see 2004 papers.

JD explains that esthetics played a large part in rig geometry for Maltese Falcon. But in the context of an 87 meter vessel, certainly a single un-stayed mast version would not be sensible.

found Tads good link and this balanced rig while thinking and searching
how a (up to 40% better sailing) aerorig may work in bi or A masts

Interesting Paper

Thanks Tad, I had missed seeing this paper...probably as I only had a cursory interest at that time

 

Two Large Cat orders

Just months after beginning the construction of a Sunreef 102 Double Decker, Poland's Sunreef Yachts has received an order for a 32m (106ft) multihull based on the exterior lines of the Sunreef 100.

The new Sunreef 106 Sailing is being built for a European client, and its modern interior is the result of close cooperation between the Sunreef in-house design team and the yacht's new owner.

''We've been receiving many inquiries for large custom yachts which is gratifying and supports our strategy to build these kind of boats," says Sunreef VP Nicolas Lapp. ''With our first two superyachts due to be launched in the coming years, we have now achieved our goal to be recognised as a builder of large custom yachts that only happen to be multihulls."

Headquartered in Gdansk, Poland, Sunreef Yachts specialises in luxury sailing catamarans and claims to be the first and only shipyard in the world to have under construction two multihulls over 30m (100ft). The company also builds monohulls and power catamarans, including the Sunreef 67 Power, which is due to be launched in April 2008.

I do not have a plate before my head

Ha, Fun to joke when it comes to littelary translated dutch translations but to get to your design;

Is that a skysail (a kite like the kite surfers?) kind of thing you were planning in your sketch. Great but the yacht is so heavy it benifits only a little when it comes to the uplift effect of a kite.

That sketch was just at the point of launching the kite, not for lifting.

Did you do a cost estimate compere to a more classical rig?
Cost is often the difference between possible and impossible.
The MF was possible because a large amount on money was pouring in without restrain. It is not a viable model for any boat.
But if your simplified the rig to a cost at the same level as a, let say, a full batened classic multihull rig, why not? And they are not cheap.

Bi-plane, bi-rig version

That is what this fellow is proposing, a bi-plane version:

'Bare Bones' Version

I did no cost comparison as I had no final alternative configuration yet. But this other subject thread has me thinking about a 'bare bones' version....buildable in back yard. Started writing and sketching a bit yesterday, but now headed to Florida to visit an old friend for a week. So probably won't finish that until I return.

 

Misadventure past chartered waters

DynaRig sounds impressive, but a sail by any other name is not much of a sail if it doesn't function as a well designed wing. When it comes to determining the best sail design there are no uncharted waters. It has been proven time and again that nothing beats a Wing sail.

Why venture past chartered waters when what you seek is staring you in the face?
