Why did hydrofoils never take off?

Eemm anon are you retarded?
Hydrofoils arent made for take offs.
They skim above the water and thats it.

>loud af
>slow af
If we never invented planes or buses they'd be alright

>>2044074 (OP)
because soviets were too good at making them so america had to discredit them as being commie shit not worth pursuing
also they are taking off again

>68km/h
whyyyyy

One issue is draft, a lot of places need dredging to accommodate them. For public transport the higher speeds are actually probably a negative because you'll only have the biggest of brainlets operating them.

Not enough lift, not enough thrust.

>>2044074 (OP)

>>2044167
I think it's more related to operation constraints, the depth you need when not at speed, the safety/stability and the fact that load capacity is often more important than speed
It is cool though

I hate America right now and they did plenty of fucked up shit in the past
Fuck israel too and fuck these ghoulish degenerates that support those crimes against humanity unconditioinally
But especially in light of the Ukraine invasion by russia and the apologism that followed I am really tired of American diabolism

This was funny and I want you to know that I chuckled

Murrica.

is that the one that the IDF massacred and the US was like "no worries bro shit happens ha ha"

>>2045054
no, that was the USS Liberty, which wasn't even a hydrofoil

USS Plainview was decommissioned in 1978. Someone bought it in hopes of scrapping and selling the aluminum hull, but they gave up. For the past 40 years it's been a wreck on the Washington side of the Columbia River. And the Washington ecology department is looking to scrap it themselves to clean up the river.

That's a shame, she must have been fun. Noisy vibrating fun but fun nonetheless.

Boeing built some. Then sold the design to Kawasaki. Kawasaki supports existing boats and is considering restarting production for the local market (Japan).

To put it simply: you get the complexity and the maintenance of a plane with the brutal environment of the sea (plus salt).

I absolutely love hydrofoils but the material science just wasn't there at the time. Maybe in a couple of years...

Glad to see the joke wasn't lost on you anon.

>>2044099
Updoots all around! If I could give you some reddit gold I would.

>because soviets were too good at making them
lol
nothing good has ever come from russia

>>2044074 (OP)
They only really work in dense archipelagoes with a lot of islands. Where going by slowboat is too time consuming, but helicopters/planes are inefficient (and take-off/landing consumes too much time as well given the short distances).

Alexeevs, a hydrofoil designer took the next step and lifted the skis out of the water.

Hobbled by the same thing as the Concorde: fuel costs. You have to burn a lot of paleozoic plankton to get a ship going fast enough to fly. It's just hard to get enough passenger volume to make it profitable. They also require relatively calm water, so their routes are limited.

I remember watching those going to and from Victoria, BC on its way to Seattle in the late 70's/early 80's. It would clear the Inner Harbour and Odgen Point breakwater like a normal ship. Then when it was off Brotchie Ledge you could hear the engines rev up and as it gained speed quickly, it rose up out of the water and was gone! Impressive and fast. Very smooth even in the roughest conditions.

>The Island Jetfoil made waves on the Seattle–Victoria route during the summer of 1980. Designed for passenger comfort at speeds over 45 knots (83 km/h). For context, today’s Spirit of British Columbia with BC Ferries cruises steadily at about 20.6 knots, while Hullo’s vessels travel at a swift 38 knots.

I think any niche hydrofoils wouldve filled have been taken over by those high speed catamarans which are about 85% as quick with about a tenth the complexity/operating costs/dredging requirements and other hurdles anons have listed ITT
All that said, if money and practicality were of no cosequence, for me its the Mountbatten class

I always liked this pic of Princess Margaret. That doggie in the foreground is going to get a surprise.
