Student Design, critique?

Well, we've gone from Star Wars to Civil War, but now you have a much more functional design...

Tough love as always Henning.

Thanks.

Here is the latest, I ditched the Dynarig. Added a keel and rudder. Do you think the jibs are raked too steeply?

Also, everyone is catching the tapered mainsail battens as a Chinese visual cue, although the sails are not a Chinese design functionally.

Using horizontal battens, to me isn't as aesthetically pleasing. I need to find an excuse to use the tapered battens. Also I'm not sure, but would the tapered battens cause problems with the sail's airfoil shape?

vling, i think u should go back to your original idea and make it work, there's no reason why it cant. u might have to modify the bow and stern slightly (reduce length). your last 2 designs are nice, but they are a bit mainstream. comments?

The thing is, the laws of physics regulate hull design, not the whims of design.

The battens are not a deal killer and do look good IMO. Once you move the mast forward some to where it belongs, the jibs will be at a better angle. (take the square surface of all the sails and then find the median longitudinal point of area, that should be just aft of the center of longitudinal effort. You are now far aft). You also don't have a provision for an overlapping headsail such as a Genoa to take advantage of slot/venturii effect in lighter airs.

LOL. I'd just turn around the pilot house and sails and run it the other direction, she'd do just fine that way.

Post #13 showed a beautiful piece of art. It kind of went downhill from there.

vling · 10-24-2009, 03:26 PM

84 Far - Sure give it a try.

Marmot - Thanks. That was the aesthetic I had in mind first, although functionality came in to ruin the party :P. I tried to retain some of the feeling of it in the final version though.

Henning - Why won't overlapping headsails work in this situation?

Execute that esthetic in SS and/or glass, find a gallery, and you might be able to finance your education. Seriously, that design would make a beautiful work of sculpture.

Haha, maybe I'll have to take metalshop next year.

I would encourage that in any case.

I was referring to headsail overlapping the main.
