1950´s sailing hydrofoil 3D model

Monitor 3D model,
 youtube rendering movie

A couple of days ago I wrote about the famouws Monitor of the Baker company.
15 years ago I researched the Monitor using the internet and was pleasently surprised by the information that was still available.
This I wrote about on my website wind-water.nl on the Monitor pages.

Today I put together some old renderings )from 1999and 2001 of both the original and the intended Monitor model in a youtube movie.

Although the Baker company had a US military contract for the Monitor it still was too expensive to build the intended dual wingsail version, with a more elaborate hydrofoil setup
Imagine what it would have been a wingsail hydrofoil in the 1950`s almost imaginable. The speeds they are said to have reached are now 35kn´s what would they have been with the wings...

If you wonder how height control is realized with ladder foils. Its relatively simple the decrease of submerged foil area with increased ride height is the main factor.
In Monitor things were made a little more subtle with the mechanical computer controlling pitch through the rearstay force and the roll through the stays, very clever stuff by mister Baker and particularly Niel Lien.

Sailing hydrofoil without hull

Le bateaux volant, the flying boat

The Swiss Mirabaud team, of Thomas Jundt, has been developing an 18ft hydrofoiling skiff form quite some time now.
I have been looking in my personal "archive" and the earliest pictures which I could find you see below. I remember how exited I was as at last someone was trying to T-foil something else than a multihull or a moth.

 
I am not going to present a timeline but a very interesting next phase was Mirabaud trying their hull less version. Obviously that has some drawbacks, as they needed to be towed to speed and any mistake would lead to another tow, some images below and there is an interesting youtube movie also.

Now they re-instated some kind of hull, small and consequently light, and the inevitable wingsail has emerged, quite a sophistcated craft they have produced.
Here is their website.

Here a nice youtube movie of them foiling.

and below some pictures.

1950's sailing hydrofoil Monitor

Monitor

Baker MFG. Co.

One of the earlier succesfull sailing hydrofoils was Monitor built bij Baker mfg. co.
Imagine in the 1950's what exhiliration this must have given.
Some very interesting webpages on Monitor are found on the website wind-water.nl

The ladder type hydrofoil has inherent stability as the lift decrease with ride height. But they had e cleverly designed mechanical computer which used input forces from the stay's to control the angle of the rear foils.
Sailing speeds in excess of 30 knots were reached which is amazing for the fifties, as it took other craft more than 30 years to once more reach those speeds.

When you are still interested have a browse arond the Monitor pages of wind-water.nl

The wingmasted version is a rendering of the originally intended  boat, for which they had too little funds! That would have been a true revolution!
The times when we stil believed anything was possible.
