Well, this is the design brief. I want to build a hull in the computer that will have enough reserve buoyancy that even with the weight of the...
Thanks very much for the considered response. I think you're mostly right, but I started this thread as a thought experiment because I thought...
Dude, go troll somewhere else. There are two kinds of people: those who are part of the problem, and those who are part of the solution. You're...
I'm surprised that you're surprised, as we seem to be in agreement. I don't disagree with anything you just wrote. However, to build such a...
As this is my thread, I must insist you read the posts here with more care. Sail boats, dinghies especially, need wide hulls for righting moment...
I'm 6'5" and will be rowing oars with a sliding seat. The oar handles get pushed down to slide just over one's extended legs and knees. I've...
I'm not seeing it. Will keep trying.
It could even be like Formula 1's Kinetic Energy Recovery Systems (KERS). Charging a little battery, and then used as a docking engine when the...
While I'm not smart enough to put into design applied mathematics, I'm grateful for your effort, AK. It's rewarding that you're getting what I'm...
Beats me. At first thought, there's no reason these principles wouldn't work for a shallow draft powerboat, or sail. There'd have to be serious...
I question your physics. The oars accelerate the hull. I don't think much differently whether the boat is dry or has 20 gallons inside. Once the...
Now, finally, we're talking. This is the kind of response I was looking for. I'd love to know some more resources on how you got these numbers....
I'm going to quote you on my thread. Thanks for that. I'd like to know more about how to get the numbers you gave. Could you reply there? Many...
No offense, but I find this kind of response frustrating. I'm designing my own boat, and while light, it won't be a shell. And if the bilge has...
Thanks science, but again, I don't want to put additional energy into the oars. I'm looking for a solution elegant enough to use the existing...
There simply isn't a really good solution for ocean rowers. I have a system in mind, but it's relatively simple and as no one has done it, there...
River Runner, you're in the wrong thread, no offense. This thread is a serious course of education on boat design. It gets sophisticated, and is...
I was also hoping to get a real pro's comments as my grasp on hydraulics / hydrodynamics is at a layman's level. Suppose you design a bilge that...
A powered scupper gate might be another solution. Strong enough to prevent water from entering when following waves put it under water, fast...
My concept is inertia only, and with practice, the timing could be achieved. One quibble with your comments: the 'drop in forward momentum' would...
