I have a new Sprit sail from Really Simple Sails, Mike Storer. It was reasonably priced, the quality is impeccable and it pulls well! Now that...
Wow, CarlosK2, good sources and explanations. You seem to have some experience and knowledge in this field that I miss - still. But it is...
Carlos II, thanks for the videos and the comments. My hangliders were from the old style, triangular. Glide ratio 4 to 1, one had to run long and...
Hello Boatmic, Thank you for your comment, which provides some practical insights. However, I must clarify that my goal isn't to improve an...
Here is my hypothesis: Please take a look at the Goose by Michael Storer from minute 4:00 in the following video ([MEDIA]) before considering...
Sorry, Carlos II. There was just another answer from XChat GPT 4.0. I asked Chat GPT 4.0 the question I have about flat-bottomed boats. Here is...
Hi CT429 – having a rough day? I'm not a particular fan of Bolger, but saying he wasn't a good sailor, had no significant training, and that some...
Carlos II, they show the typical rocker curve. For flat-bottomed boats, this curve is approximately the same as the sheer line curve, which Phil...
I agree, the classic flat-bottomed boats were quite safe as they were used professionally.
Sorry, there was a typo. The boats are 6,5 m long. I corrected that. Another way to explain the prominently raised stern of the early flat-bottom...
"The boat you showed is a one-design class with a sail area of 10 square meters. It was chosen after a 'wild' period of designs with the same sail...
Here are 3 examples of the distribution of rocker of classic flat bottomed boats. Source: American small sailing craft. Garvey, sharpie skiff, New...
Back home in Munich, I read all the new responses and immersed myself in: "This might amuse:...
Oops, I did not see your answer, Michel. Of course, the rocker curve of the Sharpies does not originate from a NACA profile - how could it? But...
A rough example, not to scale or build: [ATTACH]
Waiting for material for new sprits for the new sail, this time from really simple sails (well made!), I started another discussion. See: Naca...
Yes, PhilSweet, the displacement of a boat, its buoyancy, represents its potential energy, which manifests through the addition of motion with...
ops, I am of course referring to the flat bottom curve *viewed from the side". I guess they call them "rocker" in American - who knows why. It's...
[ATTACH] Agreed, the pressure distribution suggests that such a profile of the bottom indeed offers little reason for a flow around the hull from...
This is the pressure distribution along a Naca 0012 profile flowing from the “front and one from the rear” resp. 0 and 180 degree / 10 an 170...
