it bugs me that the personnel are so exposed in a ge style hovercraft, coanda effect craft maybe a double shell protecting the props i think you can change pressure under the craft for steering instead of pressurizing the entire belly i think only only the lip of high pressure can hold up the craft like a homes foundation, load on the outer walls

never, they're loud as fuck, very fuel inefficient, the entire point of them is amphibiousness which is irrel for a ferry, and it turns out waves exist and will btfo you hovercraft 9 months out of the year

/n/ will unironically defend shattering the windows of 30,000 houses every day to get oligarchs from london to new york in 3 hours flat but a little comfy hovercraft noise that doesn't hurt anyone except some walruses is too much

Probably not the best place to ask but seeing you cruise ship autists here
I've been curious, if you had waves of about 4 meters or so, how much would a cruise ship rise or pitch? I've heard you don't even feel the movement on modern ships, but I've been wondering if the ship actually moves the same amount up and down and if there's way to calculate the movement

>>2066469 Each hull behaves different during sailing. Modern hulls are generally safer but a big factor is freeboard height which acts like a solid sail against strong winds.The hull motion is calculated on computer models during the planning. Also cell type balconies increase the surface contact impacting rolling. Of course, stabiliser fins are helpful in adverse conditions but increase the ship's resistance to waves. Officers do a lot work at passage planning making sure passengers are affected the least possible.

I want self piloting hybrid yachts, where they have a motor but also use sails that are electronically controlled for through pneumatic wind gauges. Something to make solo sailing possible for a person out of the box.
