The Design Process...

Very interesting. Inverted strakes with no pad. Deadrise looks to be around 24 degrees. Should offer an extremely smooth ride while providing good aeration. As you know, I'm not a fan of duo-delta conic (single step) hulls for high speed apps, but at commuter speeds... it's a very good choice. Fast planing, very little bow rise and good longitudinal dampening.

Good hull design Lars!

BTW... I would think the extension boxes would negate the use of trim tabs to some extent? For example... if they are running wet, they would counter the effect of your tabs?

Optical Illusion

Sorry about that AMG. I was looking at what appeared to be a horizontal foil just above the top of the barrel, with a vertical strut, and a dark area on the hull's bottom that appeared as a recess for that foil.

Thanks Lars for those pictures.Looks like she is coming along very well and will be launched soon .Has the inside been fitted out yet though? Nice planing hull.

Thanks Lars .I had some problem with my computer but now things are up and running again,
She looks very nice in the trials , nice turning abilities and sure a 46 knots speed is brillant.The interior is neat and compact.
Nice boat.

Lars,


I like your styling on this beautifull boat. Thumbs up!

More pictures maybe?

Lars,
I was wondering what computer program you use for your renderings. Also, it seems to me that you begin immediately on the computer without any hand-drawn renderings. Am I correct to assume this?

Cheers,
Vance

Thanks Lars!
One issue, however, that I have heard again and again, is many customers are discontent with the "coldness" of many yacht desgins. Many people have attributed this to the reliance on computer programs for yacht design. I have even discussed this with Carlo Nuvolari. He relayed to me his belief that for a vessle to truly be beautiful, a designer must start with a pencil and paper and only once the lines have been established can he move to the computer. What are your thoughts?

Very interesting to see the offset cabin! Are there many other builders in Europe doing this?

Artistic Factor

Along these same lines (no pun intended), I once wrote a reply to a magazine about an article on Ray Hunt designs:

Subject: Soundings Article by Ted Danforth, Jr.
Dear Ted,

Just finished reading your article about Ray Hunt in the June issue of Soundings, I wanted to write and let you know how much I truly enjoyed the article.

You captured not only the factual history, but more importantly, some of the essence of being involved with yachts and yacht design itself….. "the measure of total understanding of the nature of a boat."

And most importantly, you included the oft forgotten element, the sheer line. What a terribly important factor! Romantically stated, but oh so true, "it is simply her sheer … sheer beauty that is. She enters the harbor like a beautiful woman entering a room. Her sheer is the line we try to get right when we doodle boats." So many of today’s boats lack this beauty, and correspondingly, some of the essence of yesteryear’s yachting.

Your article brought some of that feeling back to me…some of that feeling that first inspired me to want to learn of sailing yachts and their design ….that had me putting together a scrapbook of designs, both good and poor, for future reference.

Now it so happens that I got quite heavily involved with multihull craft because here is where free thought and innovation abounded, and here it is even tougher to create a pretty sheer line.....

The point I wish to make is that it does seem very tough for the computer drawn lines to make a pretty sheer or bow flair line. Certainly Lars has shown this not to be. His designs are very pretty.

His method and choice of software are interesting to those of use who do not yet use a computer for design, and are looking through the huge selection of boat design software to try to make some decision on which one to buy and spend time learning?? I for one get lost here.

I assume its this 'comfort factor' that you have with this older software that keeps you using it.
1) Do you feel that a new comer would have a relately easy time learning this software compared to some of the newer programs?
2) Have you found a newer program you like?

I believe you have an inherent 'artistic' ability that goes beyond the 'yacht design' ability, and most probably this is something that should be considered by many yacht design firms....they should reach out to the 'artistic' community. On the other hand I tried this recently with an art school graduate who expressed a great interest in yacht design. I was not impressed with his abilities...too many straight lines. (probably drawn by computer)

As I suspected. That this would allow an extra wide walkway on a design that is otherwise modest in beam. Here in the US the walkways around the cockpit structure to the bow have become entirely cosmetic! Very narrow, just a few inches. And in at least one popular cruiser I have seen the railing ran up the middle of the walkway, instead of the outer edge. Thus completely impossible to use!!! But still had the classic look, railing and all, from a side profile.

BTW, nice photo from your boat show!

Agreement

I have to agree with 99.9% of Lars commets over the period this thread was started... There are a few 3D software packages available for all aspects of 3D design.. I was aske a couple of months ago to produce a lineplan and mods for a YES/!! 283mtr ship.. I asked would you like a 3D model.. There was a look of astonishment.. So I did the whole project in a model then transfered it from Microstation to Autocad so the 2D guy could use it.. I dont like Auto cad but this way worked quitwe well.. However ,,if there are any Microstation users here reading.. tell me why u cant cut thru a parametric of curved solid anymore.. if you look at a jpeg from a model I built some years ago Under the oceanco/Alfa IV thred , there you can clearly see I cut thru the transom for the freeing port. spurling pipe and more so the passerelle I designed for the yacht.. Now I cant do this with Triforma..Why???

For the most part, If I understood lars correctly, I'm not really into hulls and calcs to do with.. Give me something an owner want to do, something no other yacht has.. I'll design it. Toys, passerelles liferaft launchers..(Lady Christine) I think Lars you love your work as much as I do!
