Some more gen ref video - 110,000 ton containership steering system. [MEDIA]
The former chief of the Port of Baltimore who oversaw the salvage of the grounded containership a couple of years ago said something that...
Are the beams old? That may help a little here. You need to find out what species and where harvested, and if possible, how old. After resawing...
Please tell us the specs on the prop on the old boat (and tranny ratio), and the prop that was repitched (and the new boat's tranny ratio). And a...
Oak is good for beams but a poor choice for deck planks. It moves too much for deck exposure and will blow out pretty much any fastening system....
This video has a decent list of links for general background on the ships, propulsion, steering, and port operations. Sal Mercogliano's What's...
Yes, use bigger pieces first like tops suggests. USCG used to require that, probably still does.
Is the smoke from an attempted emergency reverse air start? Doesn't look like it had enough air to pull it off. If going 8 knots, that's too fast...

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...
