Platt Montfort is a designer of some substantial reputation. Certainly if one is interested in the question of building ultralight boats then he must be...
... I don't mean to pile on poor T., but the question he asks above is one that no one who understands the basic elements of logical thought would ever ask....
... I thought it was much more interesting to get in one of my boats out on the Bay, then let it go sideways to the waves. Actually, it was quite comfortable....
BLQ wrote about the example of fish shape. I ca not find the post now. For me this example is best suited for forms that are under the water, such as foils,...
... Lew was speculating that that's what you meant. I never made such a claim, which is why I found your statement puzzling and I didn't know what you are...
... I did hear about someone who had a bad trip on LSD....Oh, wait, that was something entirely different. ... OK, guys, we are starting to degenerate back...
It's as simple as this... if you are going to lift this speculative boat from the bow and stern, you will be doing it by the structural integrity of the keel...
This comes down to the scientific method using experiments with observation with controls. Do we follow the scientific method when making our claims, or do we...
The lattice? How else can I explain it without drawing pictures? Picture a series of ribs made of 1/8" ply, spaced 3" apart, 3" wide, interspaced with a series...
I used to lift the 21 foot boat by the ends, but it had a light stiff cored hull, and the keel was only about 400 pounds. Total weight about 1500 pounds. Did...
We already know that two people can witness the same event, and provide two different desciptions. Lets not say the opinions that differ from ours are yarns....
I considered these designs and building materials. To give an indication of the difference between wood and this construction, my one sheet boat weighs in at...
Yes on most points. Fish have figured out that you don't want to run on the surface, so mostly the don't. Porpoises, OTOH porpoise, which as it turns out is a...
... Oh, so that's where it comes from. I didn't say it, you assumed. The idea as I have it drawn up has the whole hull built up as a cantilever structure, much...
... Lew was speculating that, if you pick it up by the ends, the keel would do most of the "bridging." Lew could be wrong. Lew overlooked that, for example,...
Michael: Back when I was in college, I was taught that in order for a study to be called "scientific", it has to meet two criteria: it has to deal with...
Lew: Don't be so down on yourself. The boat will be decked over, there won't be gunnels, rather the deck will cause the whole hull to act largely like a box...
My mother would say " The proof is in the pudding " I can wait. In the meantime I will be sailing. Michael ... to be called "scientific", it has to meet two...
Lew: Yep, you got it. As long as I don't run into anything, like a reef or sharp rock, 1/8" ply is more than enough to keep the water out. But should I run...
... Having defined "science" pretty well, can we now proceed to define "egregious overgeneralization?" Note: An example is often illustrative, but does not ...
... Lew will try to get over it. Lew knows that you will not think him sarcastic. ... Interesting. Re box girders, see also my remarks on I-beams. An I-beam...
... OMFG. ... History is just one damn thing after another. - Winston Churchill ... __________________________________________________ Do You Yahoo!? Tired of...
Here are some further comments. I like Lew's approach of just looking at a box. ... BobLQ writes: Hmmm ... smells like an awful lot of wood to me, Lew. 96 m^2...
... Tens are overrated. Harrumph. Given a skin at ~~1200 lbs, I still question the 3000-5000 lbs all up displacement. OK, I question the 3000 end. Consider...
BobLQ: I would prefer to use foam for the very reason you mention. My question is, which foam? Foam requirements: closed cell (waterproof) somewhat plastic...
... I discounted it by (140/40)^2 = 12.25 I thought about discounting it by the cube but decided that the area of the box, which was what you used in the ...
