Mentor Pilot recaps MH370 after ten years. This is his first published video on the subject. [MEDIA]
My main concern is reliability in that offshore environment. Yes, you need more battery capacity for sure. If you wake up after a long haul, where...
Just calculate the membrane tension needed for a 5% camber, 2 meter deep, 1 meter cord fabric supporting 2.5 tons of side force. What sort of...
It's complicated - but the momentum doesn't care one whit. It's all buried in how you achieve it with mechanicals. cross posted with baeckmo - I...
Shouldn't there be some area correction for the surface piercing props? I think I used an arbitrary 40% for fixed surface props intended to run...
That is certainly an option that we know exists. I'd prefer a higher voltage solution. There exist a decent number of inboard e-motors for...
I don't know what inducing it either, I just know how stuff responds. The finer bow responds with a greater pitch angle to whatever is pitching it...
You're going to have some significant warping based on what you wrote. The plug needs to be super strong. Remove the foam and strip with 1 inch...
Um, no, it's the other way around. The very fine entrance has a tiny waterplane and lowers the KM(l) value compared to a bow with a greater...
You need to post a detailed sketch with dimensions. Show the area on deck that it gets attached to, and the attachment method. You need to specify...
I only mentioned it because of the picture of Jake Free's trimaran that portacruise linked to. It looks like the same idea. Mine had a sideways...
Higher efficiencies than what? Slow speed boats have low prop efficiencies on paper because of the higher relative slip values of their props....
If you want want some examples that are easy to understand and visualize, try Ruel Parker's Sharpie Handbook. For a bit more advanced examples,...
Okay, so on the shore side of things, you need the power company to hang a new 200 amp meter service. You need the breaker box and a home run out...
You need to decide first off that the point is to design precisely one boat to meet some set of requirements. All performance metrics must be...
What load? You need to be very specific. The relative performance is very sensitive to weight. Catamarans always have a lot more wetted surface...
When it's floating, it matches the center of gravity. That's what you get to decide on.

She got no hips! Add two or three feet of waterline beam around station 3. The reason few boats have water ballast is because it is so bloody...
Short answer, you can't cartop a three person boat (other than a pure canoe, and that isnt easy) unless your car dates to the 50s. I'd be looking...
