Tord, I'm sure you're right that high-tech junk rigs have a lot of potential, and I think they will probably receive a fair amount of attention from serious...
Last week I took a few days and sailed Slider solo down to Fort McRee at the tip of Perdido Key, a really great cruising destination not far from Pensacola and...
... Indeed, too many inventions at one time often is the road to disaster, unless you have lots of time, money and patience! We went that way ourselves, with...
I am looking for high-level books on the physics and engineering of sailing. Articles would also do, but they need to be "refereed" and actually published. I...
... The would be Marchaj. http://en.wikipedia.org/wiki/Czes%C5%82aw_Marchaj As Phil Bolger once wrote he seems to make a lot of sense if you can figure out...
... As to the answer to this question. Since you are looking for pretty advanced information, I'll give you a medium advanced type of explanation. If you have...
You forced me to say something. I like it, I like it a lot. Did you read the piece on SA where a designer gave a pretty good account of why he used two rudders...
Thanks. I got interested in weather helm when we unsuccessfully attempted to investigate if Zeiger's barge shaped trilobyte could go against weather, or would...
... In my explanation, I concentrated on the rig, but the hydrodynamic force vector moves around depending on angle of heel, the amount of leeway, and the...
... No pics of your models, so, though lee boards are mentioned I'm not sure if they were actually fitted. Some thoughts: The hull clr alone will be more...
In his book Sailing Ships, Colin Mudie talks a little about old time sailing ships and the fact that they didn't have a keel in the modern sense. That is, they...
... If so, then wouldn't the observation be different to that actually observed for these models? That is, the Trilobyte should have had the larger degree of...
To add a couple of things. A boat with a balanced rudder may steer itself, and deal with the changing affects of wind angle and speed. The same boat with a non...
http://www.youtube.com/watch?v=e9fWCHsdWjk We chased this 125ft schooner for a while on Saturday. Best I could tell, she was doing the best she could upwind,...
I just put up a new video-- the first part of my solo cruise in late September. http://www.youtube.com/watch?v=EmQJOqJwhvY There's some footage of porpoises...
Who spotted the announcement on John Welsfords website that he is beginning a design and build project with a specific voyage in mind? I followed the Sundowner...
I'm getting down to a little design work for the first time in ages. http://intheboatshed.net/2008/10/11/intheboatshednet-skiff-progress/ What do you say...
Seem like someone is always looking for a small cruising boat. And while I was playing around with a design for the AIT race, I came up with this. I was...
I have been thinking about a rowboat for a while. Your design looks like it would be a good around boat. I could see rowing it for exercise, or taking it out...
... I think they are harder to design then they look to be. The proof is in the using. I started to make a 15' rowing skiff of ply panels wrapped around one...
... Thanks Peter, it certainly is a ubiquitous form. But it can produce good numbers. And is a no brainer for ply construction. That is probably why there are...

I added 2 files showing how I like to check the the lower side panels in a multi chine design. I used to do this by hand. Nice to do it with the computer now....
I'd say that there isn't an enormous amount of room for variation. If the boat's going to be flat-bottomed, 4ft across the beam and have a design displacement...
