Help with getting my monohull onto its hydrafoil

[Greig]

Hey guys, I just got a jeanneau 44i and I'm having trouble getting it up on its hydrafoil like the Americas Cup yachts. I've had a spin cycle bike rigged up to the propshaft to give it a bit of a boost but I run out out of gas before getting it up there.
Any advise would be much appreciated as I'm training for selection for the next 1

Bolt an SRB onto each stern quarter. You'll get up & foiling & then some! A JATO package would probably do the trick too.


SRB = Solid Rocket Booster as in from the Space Shuttle

You are obviously lacking in the sail department, I am not sure where you get those fancy articulating solid wings though....

From reading your post...the only thing I could suggest is getting in a bit more shape...your principle sounds right. It's just that you are running out of steam before she gets on plane..

I agree with Uncivilized. In the late 70's my cousin was crew chief on the Miss Budweiser rocket car that they attempted to break the speed od sound with. After several unsuccessful runs at daybreak at Edwards Airforce Base over the course of a few months they strapped a Sidewinder missile, sans warhead I assume, to the top and the driver who was a stuntman named Stan? Set it off when he reached like 550 mph. They hit mach I going one way, but to get the record you have to turn around and go the other way the same day, and they couldn't do it. The payload of a 44 foot monhull is considerable, and the friction of water is a lot more than air, so I think something closer to a V-2 or a Saturn rocket is in order. Also mach I is lower at lower temperatures, and is why they launched the rocket car at dawn on the dry lake bed. So I think to get up on a plane a polar location is in order, sort of like WC Fields yacht " The Gigantic" in " The Great Radio Broadcast of 1938". I want to watch.

The foiling cruising trimaran I saw in Sausallto in 1969 had no rocket assist. It was a plywood amateur built and got up on ladder foils in a breeze. It was sailed from San Francisco bay to New Zealand and back. It is a common misconception that only carbon fiber wing sail boats are able to foil. And remember that Alexander Graham Bell built the first foiler in 1870. Not the current high tech times.

You were foiled in your attempt to foil? So you were foiled then. Or did you want the other type of foiled?

[DrivinSteve]

I believe you can but an upgrade kit from ACME.
I suggest you send an email to wylie.e.coyote@ludicrous.net for the part #s.

Foiled again?
But suggestions of enormous power and other absolutely impracticable ideas shows lack of lateral thinking. Clearly the answer is a large bundle of helium or hydrogen, if short of money, balloons. Attached to the mast head. Simple eh? Foiling at 6 knots!! Or downwind at wind speed.

In the middle of the last century the USA supplied McMurdo Base in Antarctica using DC3's with JATO from Taieri Airport southern New Zealand. Got up quick!

Clearly an anchor problem. Need to upsize 50%, and add another 100M of chain.

More hamsters on treadmill. More caffeine. For you and hamsters.

What Foufou said... I remember reading a book years ago about some dude who foiled a plywood mono all around the South Pacific, back in the 50s from memory. Book had quite a few old black and white photo plates to prove it too. Quite an eye-opener for me, as I was playing with Windrider F16 Rave foil boat at the time (which would stand up tall and take off in around 10 knots of breeze) and also thought that high-tech tris were the only way to achieve this..
