Default HydroFoil Shapes

Hello


This is my first Post here in this forum, in fact is my first time here, but i am already enjoying it. I want to know if someone have some schemes of a Hydrofoil shape. I dont know if you understand want do i want because of my bad english[:-] (i´m portuguese).
In other words i need the basic shape of an Hydrofoil, for aplying in a boat that i´m building.


Best Regards

The easiest and most stable foil configuration to create is the "V" foil.

The PT-50, the RHS-140, or the RHS-160 are good examples.

Here are some images of a PT-50 out of the water.
Notice how the propellers are under the rear foil and the rudders are on top.
Also that the foils increase in wing area as they move away from the center line.

Here are some short thread on advanced inverted "T" foils.

And my current progress at two weeks into a build.

Good luck with your project.[8D]

Greetings


Woowww...Your boat is outstanding[X(][X(]. Very realistic


Thanks for your help, now i know how to make the shape of my hydrofoil. At first i was tempted to use a "flat bottom" airfoil shape, just like an airplane. But now i don´t need that.

Nice work Umi!

Do you have the plans of the Sparviero?
I do, if you need details, I can scan it and mail you, just let me know.

Hi Pompebled,

I am just working from the diagram/line drawings that I posted in the thread.
I am not sure how much more detail your set has but it would be nice to see them.
Other than that, I am working from photographs.

I actually just cut the tip of the bow off this morning and reshaped it, it was too round and was bugging me.

Umi
