First, think for a second. Really? Then, consider that yellow is legal too.
I dont know where the fear of expense comes from today. An iphone or ipad easily has the compute power, sensors, and I/O to do the job, and simple...
Pretty! Windward Passage was fast for the same reason all fast boats are fast: it was as light as it could be. Otherwise, it and other Gurneys,...
I am also a software developer, in my case from the 1970s. I find that starting with the user's point of view first is far better than trying to...
I can imagine it is the first crossing in 16 foot boat, but only if one is very, very precise about measurement. There have been many about that...
Regarding the sailplan: I suggest you google "batwing sail"
Good comments all. Diesel engines: lots of data to suggest its very easy and cost efficient. Just notice that virtually 100% of shipping uses...
The problem is you have all that buoyancy so deep. When the boat heels a bit, that buoyancy is right where you do not want it -- to "windward" if...
OK, I think I get it: While skins could be made thinner with a thicker core, the minimum skin thickness quickly becomes dominated by other...
Many good points so far, thank you all. Kvsgkvng, the math seems to tell me the stress reduces with thickness, in fact as a factor of 1/2d where...
The cost to triple the core thickness is something, but for certain, material prices are a tiny percentage of a total boat. True, the core...
What is the limit for core thickness? It seems that making a core 2x or 10x thicker than typical only improves stiffness and strength while...
Before getting too twisted over Sizzors having too light scantlings, weighs too little, or has too little righting moment compared to beach cats...
Good question, I'll ask someone who knows. All of my comments are from what I have been told by people who wanted my business, and was...
For a one-off build, I got far, far cheaper quotes for foam-fiberglass than any other material, even from shops that are famous for wood...
My opinions based on my experience: Overhangs matter very little to motion, its primarily a sense of style. Its not really light or heavy...
BMcF, do you have a link to those videos? From first hand experience, SES is substantially less comfortable than catamarans: in non-glass-smooth...
Dude, it is impossible. Take a high school physics class. Put down the crack pipe. I would rather encourage you, but at your level of...
The thing that often seems to happen with designs like the Diesel Ducks is that a lot can be done quickly, it seems, when its developable...
I am surprised that the red boat in the first post looks so very, very far from a reasonable aerodynamic configuration (hard to imagine more aero...
